Precious coral is a species of coral that grows in rocky seabottoms, typically in dark environments either in the depths or in dark caverns. The coral skeleton is composed of hard calcium carbonate, colored by carotenoid pigments. Coral exhibits a range of warm reddish pink colors ranging from salmon pink to deep red; the word coral is also used to name such colors. Owing to its intense and permanent coloration and luster, precious coral skeletons have been harvested since antiquity for decorative use. Coral jewelry has been found in ancient Egyptian and prehistoric European burials. Most precious coral is harvested in the Mediterranean Sea, especially in Sardinia. Deposits are also found in the Pacific, in Japan, Taiwan and Australia.

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.
