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 have been ordering from GemSelect for at least 6 years. Every single order was perfect - every item was as advertized, in perfect condition and arrived well within the specified time frame. I have recommended them to several friends.

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
