About Us

Geminex background in colored stones goes back to 1950’s. David started faceting in 1957 and became enamored with cutting opals in the early 1960’s. This interest has continued to blossom with time. 

Over the years we have endeavored to have the best in color and cutting. In 1986 we started manufacturing stud earrings and basic pendants. In the 1990’s we started to design special pendants for individual stones. After a few years we advanced into one-of-a-kind designer pendants especially featuring free form and regular shaped opals.

We hope you enjoy these pendants as much as we enjoy making them.
