Gems of Pala Mine Trip

The GIA school puts on several mining trips per year and I decided to embark on this particular not wanting to miss out on a once in a lifetime experience. We visited to Stewart Lithia mine located in Pala, California presently owned by a long time miner Blue Sheppard. This mine is known as the largest mine largest pegmatite operation in US history. Absolutely an industrial giant! A pegmatite is a coarsely crystalline granite or igneous rock with crystals from centimeters to several meters in length. Truly an amazing occurrence of nature that continues to fascinate me the more I learn about gemstones at GIA and experience the rock world outside of the jewelry store environment.

Gem quality natural pink tourmaline is fives times as rare as gem quality diamonds and more than time times as valuable as gold in it’s natural form. Tourmaline produces exquisite gemstones that are beautiful in saturation, vibrant in color and a tone that is luscious.
In the 1890’s most of the Stewart Lithia tourmaline mined was exported to China of rate Chi’ing Dynasty Imperial Court of the Empress T’su Hsi, who financially supported all of San Diego County tourmaline mining for 30 years. Pink Tourmaline was believed to be a sacred gem of the Bodhisattva Kwan Yin, is the embodiment of great compassion. He has vowed to free all sentient beings from suffering.

Blue purchased the museum 30 plus years ago and has operated it ever since. He has mined all over the world and has found incredible amounts of gem quality tourmaline, quartz, feldspar and other varieties. Many of the gemstones and specimens from this mine are in museums like GIA, Smithsonian & Los Angeles National History Museum. So if you are ever in one of those places do keep an eye out for a specimen from Gems of Pala.

As I put my hard hat on and grabbed a flash light the excitement of going into a mine and seeing were gemstones and specimens are dug was fascinating to me. I could see myself with a hammer and chisel standing on a ladder searching, digging and eagerly anticipating the next find. Especially, if you are like Blue and find pockets of gem quality stones that profit millions of dollars with that one find! Who knew mother nature could be so generous….

The temperature in Pala, CA was 87% and with pants and a long shirt was rather smoldering, yet the anticipation weight heavier. Entering the mine, I could feel the cool damp dark rock. We traveled down the mine about 400 meters, which, took approximately 20 minutes. Blue took us into the Honeymoon Sweet, which is a room that produced a wealth of gem quality tourmaline for him. As you view the photos from below the rock inside the mine is of all colors, the sparkle at times is stunning and to see them protruding from the rock, exposed specimens, what a delight for me. A world of fascination and as I continue to learn about different aspect of the jewelry trade my love grows deeper everyday.

Thank you for reading and your interest in my experience is appreciate. Please read next weeks blog, which will be a personal interview of Blue’s life as a miner and the extraordinary experiences he has had.

Please see below several photos from the inside of the mine.

Diamonds formation, from rock to beauty.....

Diamonds form under extreme temperature and pressure. Then, through cataclysmic eruption they are brought to the earth’s surface.  It’s truly amazing they survive a process so violent and explosive. There are two types of source rock that can form a diamond: igneous rock - molten lava that is formed into a solid state becoming a rock, and metamorphic rock - pre-existing rocks that have been altered by heat as well as pressure. If the temperature and pressure vary just slightly, or the diamonds take too long to be brought to the earth’s surface, graphite is formed, not diamonds. This is why large diamonds rarely survive in one piece.  Precise conditions need to be in place, and the volatility of impact is enormous. The diamonds are brought to the earth’s surface by either kimberlite or lampoite, and sometimes, a geological process called emplacement delivers them to the earth’s surface.

After arriving on the surface of the earth, diamonds can live millions of years in rivers, streams and ocean tides before being found my a miner. They might wait hundreds of millions of years before arriving at the surface. The diamonds that exist today were most likely on the earth’s surface 20 million to 2.5 billion years ago. Now those numbers I find astonishing.

Diamonds have the highest hardness on the Moh’s scale (an industry wide geological scale), and can be contaminated by very few types of impurities. Some of the diamonds are gems with non-gem qualities. They can be used as sandpaper surface, or as tools for cutting, grinding and drilling for many different industries inside and outside of the jewelry industry.

Today, diamonds are more available and affordable than at other times in history. Yet, while they are abundantly available, diamonds with high clarity and color grading are still very rare, and of course, those stones are very valuable.

The world of mining is challenging, from finding a source that will be profitable, to dealing with ecological, environment or political conditions, it is an expensive undertaking. One is looking at hundreds of millions, if not billions, as an investment to embark on the process, hoping for a profit. It requires intense exploration, years of planning and construction, and on top of it all, potentially profitable diamond sources are very rare. Yet, there are mines that produce gem quality diamonds which have been in operation for decades.

Until the eighteenth century, India was the world’s only major diamond source. Today’s diamond sources are Canada, the US, Brazil, Venezuela, Guyana, Russia, India, China, Indonesia, Australia, Guinea, Sierra Leone, Ghana, Dominican Republic of the Congo, Tanzania, Angola, Namibia, Botswana, Lesotho and South Africa. Namibia is perhaps the largest marine diamond deposit in the world.

Please see below, the amazing diamonds we offer at Provident Jewelry. We provide a selection like no other from very petite, to 20 carat rings, and all of them have their own unique character as well as beauty. I hope that if you did not know much about diamonds, this article helped you appreciate what it takes for a diamond to be available to you, and trust me, I only shared a portion of the process. It’s remarkable what our mother earth creates for us, and what a privilege it is that we have the opportunity to appreciate this beauty.

Thank you for reading and as always sparkle on…..

Amber the organic gem

Amber is tree resin that has hardened over time. To be called amber, it needs to be at least 1 million years old. Anything less in maturity is known as copal. Amber artifacts have been found back as far as 10,000 BC by archeologists and used ornamentally since that time. In German, amber is referred to as the “burn stone”, or bernstein.

Interestingly enough, the most sauté after-color is red. The majority of the time we see amber in yellow to  golden orange, and transparent in appearance.  Amber comes primarily from the Baltic Sea region of Europe and near the Baltic shores of Denmark. It is very light weight helping it to float in salt water.  Weather, as well as erosion, releases the amber, and it ends up on the beaches. Then people gather and bring it to market. 

When treated with heat and oil to improve its appearance and marketability, the side effect can be circular marks, which the trade refers to as sun spangles. Sun spangles often have an attractive look, making the amber piece a little more unique. Heat treatment clarifies the gem, otherwise it would remain cloudy and not as visually attractive. 

Amber is a lovely gem that can be big and bold without a heft to the piece, making it easy to wear. See below several pieces of Amber earrings and a necklace from our collection at Provident Jewelry.

I hope you are able to walk away with at least one fact about amber you did not know prior to reading this week’s blog post, and thank you for taking the time. I wish you a good week and until next time, sparkle on!

Phenomenal Gems - The Feldspar Family

Phenomenal Gems - Labradorite Feldspar & Moonstone Labradorite Feldspar

Feldspar is most widespread mineral on the earth's crust and has some of the most diverse gemstones. I have designed jewelry using Labradorite Feldspar for years, not knowing that this gemstone was part of a large group of related species with several different varieties. The feldspar group has many members. Some are suitable for jewelry, while others are not because of either their lack in durability or availability. Members of this family vary slightly in chemical composition and sometimes crystal structure. The gemstones vary widely in appearance and it is the chemical elements that make up the appearance. Interestingly enough, some of this family has a phenomenal appearance while others do much the same way as some people in a family stand out more than others. 

Moonstone has been very popular for decades. In the 1960’s during the “flower child” movement ,it was popular for it’s exquisite beauty. In the 1990’s ,the New Age movement turned to it for it’s natural beauty while the luxury jewelry industry started designing with it in the early 2000’s. I personally became aware of the gemstone then, and have loved it ever since. Several designers, whose work I admire,  such as those from Saks to Nieman’s, who have used Moonstone in their collections. It’s a stone that catches your eye because the vivid adularescence, which is noticeably appealing. Anything sparkly interested me, which most of you know by now.

The moonstone is a variety of Orthoclase while Labradorite is it’s variety as well as species. Top quality moonstone is found in Sri Lanka while commercial grade, which is primarily most of the gemstones you and I will see, is mined from Myanmar and India. Most often you will see moonstone in as a cabochon gemstone. It is so plentiful there are calibrated sizes, meaning standard jewelry size stones available a the wholesale level.  Another labradorite variety is Sunstone that is mined in Oregon and is not treated. Some buyers search out as well as it being a gemstone from the USA.  

There is a place on the Cambria Coastline in California that is called Moonstone Beach and after a heavy storm one can find moonstone gems on the beach amongst the rocks on the shore line. During the storm the water churns up gemstones, separating them from the earth's crust while the surface to the beaches shore line. This is a place on my bucket list! If it wasn't a 5.5 hour drive from San Diego I would venture there several times a week while here in California to see what I can find. 

Blind Pass Beach on Sanibel Island one can find sharks teeth on the beach on any given day. It's amazing what mother nature provides to us that is both beautiful and fascinating to explore.

Labradorite was found on the coast of Labrador ,Canada around 1770 ,by a missionary, hence the name Labradorite. This stone is used decoratively, often as carved into designs for a richly patterned look. Fine Labradorite Feldspar shimmers with a unique iridescent phenomenon that you can see below in some of the earrings shown. 

If you have not been aware of this gorgeous gemstone family, I hope you can appreciate and find a love for this stone as I have. Thank you for reading this week's blog and until next time sparkle on…..

Although to me, it’s a personal preference in color composition that makes you happy when selecting the perfect piece for you. At the end of the day it’s about finding what gemstone speaks to you, will make you happy when you put it on and is something that won’t sit in your jewelry box. Jewelry is meant to be worn and adorned…...

The road that is taking me on this journey....

The road that is taking me on this journey……

This week I would like to take the time to tell you exactly how this journey has been going thus far. When I originally arrived that Friday afternoon at the Gemological Institute of America, GIA, for my orientation in classroom #207, I was excited, anticipating a fabulous as well as relaxing shall we say, "VACATION" type summer-time in Southern California. Of course, I knew there would be work involved, but truthfully, I had not expected my days to be too rigorous. I have been in the jewelry and luxury industry for more than 20 years. I design jewelry and anyone who knows me, knows that I LOVE everything about jewelry.

I missed the class orientation. It was held the week before I arrived.  My schedule did not allow me to be at the school at that time. So I arranged with the administrations office for my orientation on the Friday before the Monday school start date. I walked in and met my instructor, Tim, who showed me my desk assignment. There was a stack of 3 ring binders, books, pamphlets and assorted instruments on the desk. I foolishly asked him what was all that the stuff on my desk and to my surprise, he told me it was my course curriculum.  Shock rushed through out my body. Then he informed me I had three chapters to study over the weekend before class on Monday. Alarm set in as I realized this program was going to be more serious than I had expected. In high school I rarely found the subjects interesting, and sometimes it was hard to grasp all the information coming my way. How was I going to weather this storm that was about to take place. The thought came over me, maybe this idea of getting my GG wasn't the best one I have had recently!!!

Well, here I was, hitting the books again. Being older, and I would like to think more well rounded, my approach to studying at this time was different than high school.  Age and experience of life have helped me. Today, I work to achieve improvement of one small milestone at a time. My expectations are more realistic. The last eight weeks have been challenging. I have had to work my catoocas off, but my time here so far has remarkably rewarding. When I was twenty I would have compared myself to others, today I have learned to compare myself to myself. When I have a little victory, I make a big deal about it-- for me. This has helped me to stay here, in this course and finish out what I set out to do. There were two times in the past several weeks that I thought, I can't do this. The work is too hard and I just don't have what it takes. Well, I have accepted that is not true. That thought is was an out and out lie. I DO have what it takes -- one stone at a time, one question on the test every Friday at a time.

Oh, and did I tell you that by the last week of September, I will have looked at, and graded, 1,860 stones.  When I heard that number I almost fell off my chair. Not only do I need to see that many stones, but each week there is a stone count that is required, with a test every Friday on the course work, cumulative up to the date of information given. The final kicker was when I was informed that this course work in an Ivy League college would take 2.5 years. We are doing it in less than six months. This GIA course is no joke. Boy, did I embark on some character building work, or what???

My fellow students are from all around the world.  Some of them are the most fascinating, lovely, kind in spirit people I could ask to meet. Angel, my study partner, car pool buddy and dear friend, makes me laugh so often that I remember not take myself too seriously. He truly is an angel and the smartest, most driven person that I am fortunate enough to know her at GIA. Elizabeth, a real Nicole Kidman look alike, could not be any more encouraging. She is as beautiful as she is kind and an extremely well rounded woman. Julie, a hippie girl from Berkley, is a third generation jeweler and as cool as they come. She’s an incredible sketcher and very spirited with a joy for life to that is infectious. David, second generation jeweler and race car driver is totally laid back. He really knows how to enjoy the moment. He’s a perfect example for me of someone wearing life like a loose garment. Then, we have Bruce, who surprises me more often than not, with something I do not expect. He reminds me of my brother, big heart, funnier than funny and appreciative of life. He is a veteran who has served three tours and for that alone he deserves applause as well as admiration in my book. And lastly, I can not finish without mentioning Faris.... A 6" 4 inch, smile to melt your heart, and our class president. If I was 20 years younger I would be trying to get in all sorts of trouble with him! A true gentleman and remarkable young man that his parents can be truly proud of the person they brought into this world. These people are some of the finest human beings that I have ever had the privilege of knowing. I learn from them and my admiration continues to grow the more I get to know them. M xo

Jade ~ The precious gem....

JADE

The precious gem known as the “stone of heaven” has been treasured by the Asian culture for thousands of years for its rich heritage. The trade name for the finest quality semitransparent jadeite with its even, and vivid color is called Imperial Jade. The modern gemologists use the word “Jade” which includes Jadeite & Nephrite. The gems are soft enough to carve, but tough enough to withstand a carvers constant pounding of his hammer on the gem. Jadeite is commercially available, but top-quality is rare. Jadeite also comes in an array of colors: lavender, red, orange, yellow, brown, white, black & gray. Green is the most valuable and most expensive, it can have a price tag of over $3 million dollars per carat. 

In China & Europe, during the Stone Age, workers shaped Jadeite into weapons, tools, ornaments & ritual objects. The carvings are believed to invoke the powers of heaven, earth, and mystic forces of life & death. The ancient relationship between this gemstone and humanity persists today among native societies in New Zealand & parts of North America. In China it became an artistic tradition that has prospered for more than 3,000 years.

The Chinese culture associate jade with clarity of mind and purity of spirit. Some of the ancient symbolic motifs still used in modern carvings are: the bat for happiness, butterfly for long life, dragon for power, prosperity & goodness, peach for immortality and the Bi, the flat circular disk with a hole in the center which is for heaven. In China there is a tradition that a girl's parents give her a Jadeite bangle to wish her a good and prosperous life, it is something the girl does not take off.  She will wear it into adulthood.

The Jade gemstone has never been a powerful or important stone for our culture in the United States, but I have seen some amazing carved pieces here.  Designers today are creating modern looks that are stylish with a chic contemporary feel. Below you will find several pieces that are my favorites of the Jade we we have to offer.

Tasteful & timeless turquoise......

Turquoise is valued for a combination of its ancient heritage and attractive color. Its finest color is an even, intense, medium blue, sometimes described as “robin egg” blue.  Although, some prefer a greenish blue as seen in some contemporary designer jewelry.  This color is anywhere from avocado to lime green turquoise. The source for top color is the Nishapur district in Iran, the country formerly known as Persia. That’s why you may have heard of “Persian turquoise” before. American & Mexican turquoise is light blue, or greenish blue to bluish green in color. While Egyptian turquoise is greenish blue to yellowish green. The bluer the shade the more copper it contains. 

The stone is often cut into cabochons, but you will see it in beaded jewelry as well as flat pieces of inlays often found in Native American jewelry. In the 1970's, this gem was extremely popular. The largest and most consistent market for this beautiful stone is the American Southwest. The Sleeping Beauty mine is in Globe, Arizona, which is the world's top turquoise producer. 

I found it interesting that in the Victorian era there was a surge in ornate turquoise jewelry designs. I have always associated it with the Native American culture. Fine estate pieces from the Art Deco period of the early twentieth century are often set in platinum combined with diamonds. Such vintage treasures occupy the high end of today’s turquoise market, and Provident Jewelry has a dynamite collection of turquoise time period pieces. Below are two pairs of earrings that are absolutely stunning.

Until next week, remember to sparkle on and thank you for reading!
