Iridescent Gemstones

Iridescent Gemstones

Iridescent gemstones exhibit lustrous, rainbow-like colors that shimmer and change as they are tilted in the light, and are one of nature's most impressive creations. Iridescence is a highly-prized gemstone optical phenomenon resulting from the way that light either interacts or interferes with the structural anatomy of a gemstone. Iridescent gems make wonderful gifts that vary in price, from an affordable ammolite or labradorite cabochon to a priceless pearl.

I love GemSelect, personally. I browse their site almost daily to see all the new stones available. Their selection is pretty amazing. The quality isn't always the highest and the cut of the stones isn't always perfect. But for the price, and if you look hard enough, you can find a real gem, so to speak.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
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

Note: 1ct = 0.2g
