All these questions, and I don't have to give any blood. What a Deal... I absolutely enjoy the Gem Select emails every month. This one today was special. I always say, I'll know it when I see it. This stone today was the One. Odd and Intriguing. Thank You So Much for all that you do.

I was looking for a site with every type of gem I could want for setting in luxury blades and assumed I would need to look outside the US, but GemSelect made it easy to get everything I wanted without leaving the house! Wide enough selection that I do not feel the need to look elsewhere and pricing the same.

I love the quality, presentation and the price of the stones. I love the identification card - report they send with each stone.

Opal is a very varied family of gemstones and Hyalite Opals are possibly the most unusual.

More a gemstone for the collector than the jewelry market, Hyalite Opals can be found in Namibia, Madagascar, the USA and most recently, Mexico.

The name Hyalite means water-like and, as the name suggests, they are generally colorless and clear.

However some rare examples can be found in vivid greens and yellows with a spectacular color change and fluorescing phenomena. Tiny amounts of uranium within the gemstone cause dramatic color changes when viewed under daylight or in incandescent lighting.

In addition, the Hyalite gemstone can display fluorescence or luminescence in daylight conditions which is very unusual.

Hyalite Opals contain minute amounts of radioactivity which surely contributes to their amazing color behavior but does not pose any health dangers.
