Each piece of jewelry was inspected before manufacturing for sale to assure that minerals are 100% natural mined from the earth. By FTC rules and regulations all treatments are disclosed if the natural mined Gemstone or Diamond has been enhanced in anyway. Precious metals have been tested and hallmark stamped to assure quality. This piece of jewelry was manufactured by myself a Certified G.I.A. Jeweler & Gemologist for Authenticity.
