Most coral gemstones available today are varieties of corallium rubrum, a very specific pink to red colored species of the coral genus. Coral can take millions of years to form as the process is very slow. Fossil coral is a gemstone variety of coral that has been agatized. In the trade, Corallium rubrum is sometimes referred to as 'noble coral' and is considered to be the most desirable type of coral for jewelry. Noble coral also includes the popular 'angel skin coral', a pink to salmon colored coral. All coral as gemstones are rare and valuable.

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.
