Amethyst is our most popular purple mineral at touchstone. There are so many products to enjoy this gemstone mineral and not just made into jewelry. But, as Décor too! I Like to think of it as 'jewelry' for a room.
Origin: Most of the amethyst that we offer to our customers comes to us from Southern regions of Brazil, Bolivia or Uruguay where it is mined deep under ground. The Brazilian amethyst is known for its larger crystal forms. While the amethyst from Uruguay is known for its deeper, richer purple. From Bolivia comes the large clusters, better yet the Bolivian Bouquets that we carry.
Amethyst is formed in volcanic "vugs" that were formed from bubbling lava gases that when cooled left behind voids. Within these voids mineral rich solutions then washed/seeped through leaving behind layers of minerals that over millions of years then formed quartz along the walls of the empty spaces. Amethyst is a violet form of quartz, which is a silica, the most abundant mineral on earth. The colors of these mineral rich solutions contained iron and other transitional metals which when exposed to irradiation cause the violet color we see in amethyst. Amethyst comes in a variety of colors from lavender/lilac to shades of pink to deep purple.

Prasiolite is a yellow - green variety of quartz. It is a heat treated amethyst that turns from purple to green. It can be heated in a laboratory oven or it can also be found naturally in rock bearing amethyst next to younger lava flows. When quartz containing iron impurities is heated by lava and turns to purple. Then, at a later time that lava flow is covered by another younger lava flow that heats up the amethyst and turns it to natural prasiolite.
* "Green amethyst" is a misnomer (an incorrect name) that some people use for prasiolite. Amethyst, by definition, is a purple variety of quartz. That makes "green amethyst" an incorrect name, just as "yellow emerald" and "red emerald" are misnomers for "heliodor" and "red beryl," respectively.

Care of prasiolite and amethyst: Prasiolite and amethyst should be stored in darkness and not exposed to strong sunlight or some types of artificial light over long periods of time, as it can fade. Which makes sense when you think of how it was created.
Amethyst Stalactite Slices when cut crosswise used to make a piece of jewelry. Pictured right: On a geode you may see a what we call a "rose". When we see this on a polished geode it is a an added bonus!
New Item: "Portals" Were these portals cut from once large stalactites? Or were they crosscuts from geodes? Imagine the size that they must have started out as? Touchstone offers these vertical presentations of large amethyst slices on stands. They make for very attractive décor items. Notice that the centers are hollow with wonderful toothy crystals forming around the void.
What makes visiting TSG special:
Every year it never ceases to amaze me, that upon a new shipment it's like Christmas, seeing all of the wonderful products as they are unpacked from large crates. Be it tiny geodes on stands, tea candle holders, amethyst slices on stands that spin, accent tables, bonsai trees, bookends - its endless. touchstone is always seeking out the most unusual and fascinating to be newly discovered by you, the customer. Not to mention jewelry too! I implore you to keep visiting one of our three galleries located in Sedona, Santa Fe and Taos to be continually amazed and to find your own "treasure".
