Blue and Pink Flash in Amethyst
One of my person favorite shows on tv is Antiques Roadshow on Public Broadcasting. I know professionally or personally a number of the people who do the appraising in jewelry and art. I was watching it the other day and there was a group of Amethyst jewelry, some of which had blue flashes. They indicated that this material came from Siberia and was only found in that part of the world, so when you see Amethyst with this color flash, it came from Siberia and was typically quite old (to quickly summarize what was said).
My understanding over the past 30 years is that Siberian Amethyst had a pink flash. The blue flash I have seen in the fine Pau D'Arco Amethyst we purchased in Brasil, and have seen it in Uraguian that we have purchased, as well as in a few gems from Georgia and Maine. The blue flash is not too common, but is a nice color which appears in some saturated Amethyst. It is not seen in all Amethyst but adds a nice glow to the gemstone. The term Siberian is outdated, as the pink flash, like the blue flash, can apparently be found in different deposits throughout the world and not just from what may have been the original deposit that gave a particular feature its name.
The mis-understanding about naming and location, even among Gemologists, is due to the fact that most Gemologists do not purchase rough and see similar types of gemstones being unearthed around the world. One is dependent on items brought in or seen. When one sees thousands of gemstones per year, one increases their knowledge rapidly and sees many gems that the public or even the trade may never see. There are many gemstones that we encounter and have in stock that most Gemologists could not sight ID or even guess what they are within 3 guesses because the material is unusual in size, color, clarity or just simple rarity. Even our finely saturated Aquamarine has stumped Gemologists in the past. Many may not realize that Zoisite (Tanzanite) may be found in green, teal, pink and yellow! There is always something to learn in the gemology field. Things change annually, and it is exciting to see what will be found that is rare and unique and this is what All That Glitters is all about. Check out our Amethyst colored Garnet that is new as well as our very fine Yellow Beryl Cat's Eyes - two fairly new gemstones to the market.
