Chip inlay is a method where cavities in jewelry are filled with a mixture of crushed stone, typically turquoise and coral, and epoxy resin. The piece is then polished smooth after the resin has hardened.
Red coral (Corallium Rubrum) comes from certain areas, such as the Mediterranean, where the specific water temperature and conditions allow coral to thrive. Coral is a hardened tube or branch. Only about 10% of coral is considered jewelry quality. Coral comes in shades from blood-red to orange to pink to white.
Although coral has been used by Stone Age peoples as long as 30,000 years ago to decorate sepulchers (burial vaults), Native American artists have only used coral for the last 600 years.
Lone Mountain Turquoise
The Lone Mountain Turquoise Mine, near Tonopah, Nevada, was one of the leading producers of fine turquoise in Nevada. It was discovered by Lee Hand in 1920 and filed under the name of Blue Jay Mining Lode. At first it was called the Blue Jay Mine on Lone Mountain and later just Lone Mountain. It is presently closed.
As with most mines, it was at first a tunnel and shaft project but when Menless Winfield bought the mine it was made an open pit operation. The turquoise from this mine is mostly good to high-grade and usually in the form of nuggets although there is a quantity of vein material. A very interesting occurrence of turquoise found here is a condition where the turquoise was deposited in cavities or molds left when parts of fossil plants were dissolved out of a harder rock. The turquoise is graded into golden matrix, black matrix and spider web. At present, most of it is cut and polished or the nuggets drilled and polished at the mine, making this is a very collectible turquoise, and rarely available in rough form.
