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.

GemSelect is the best in every catagory that I have found yet. I hope to continue to place more orders to receive great gems !
Many beautiful gems on the site. Love that you are actually shipped the gem that is shown in the photos. Also cool that they give a write up of each gem detailing hardness, characteristics, and best uses for mounting. Great site! Looking forward to seeing these gems in person.
