Madreperla Mother-of-pearl is an organic gemstone that comes from the inside of some mollusk shells. Mother-of-pearl is made from nacre, which is mainly calcium carbonate. Like pearls, mother-of-pearl exhibits a pearly luster and an attractive iridescence. Mother-of-pearl tends to be the same color as the pearls produced by the mollusk and their color varies. Mother-of-pearl gemstones may be white, yellow, blue-green, bronze, pink, red, brown, black or banded. Mother-of-pearl gemstones can be natural (occurring without human intervention) or cultured, and may come from saltwater or freshwater. Sometimes mother-of-pearl is called "Cachalong opal" and abalone shell mother-of-pearl is sometimes called "sea opal". Such trade names are due to the play of color seen in both mother-of-pearl and opal.

The opals I ordered are absolutely beautiful, very fiery and well-cut. The pictures online didn’t do them justice. Shipping did take longer than expected (I chose the standard option), but the gemstones I received were definitely worth the wait.
I have purchased gems from Gem Select twice a year, for more than a few years.Gem select is the best place to buy gems. The selection and presentation are genuine. What you see is what you get, keeping in mind the carat weight, and measurements they have listed. Never have I been disappointed with any gem I have received from them. Nan
GemSelect has a great selection of smaller cabochons. Many other retailers do not. Plus, the photo of the stone is the one you are purchasing. Shipping from Thailand is nearly as fast as from within the US. Stones are tightly and neatly packaged.
