Hyalite Opal

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.

I was in the market for a replacement gemstone for a solitaire ring that I recently purchased. I was delighted to locate GemSelect as an option for the replacement gem. They have an impressive selection of gemstones! I ordered a citrine trillion cut gemstone. The pictures of the gemstones appear accurate in terms of color and size . The prices are appropriate for the quality of stones I've received. I will continue to shop with GemSelect and will recommend them to anyone in the market for gemstones.

Everything is great. If you could add one thing to your site, I would suggest pendant findings, especially for the larger sized stones.

I was looking for a tourmaline but although there were numerous beautiful stones to choose from, there was none that fit my need. Then I thought of some other beautiful stones I love and sunstone came to mind. I so thrilled when I was able to find the most gorgeous sunstone and with the exact specifications of my need. GemSelect makes it extremely easy to find the exact stone your looking for quickly and check out is just as easy to go through. I would (and have) definitely recommend GemSelect because of the large selection of stones, ease of use, and fast affordable shipping.

I have used other vendors also in the past including pandora, peoples, jtv and gemselect. Transparency is the key, please keep it up. I have seen Gem Select in the market for a long time and trust its products.

length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size
