Like many gemstones, turquoise comes in a variety of colors, from nearly white, through light blues, to deep sky or robin’s egg blue to earthy greens and yellow. Native Americans described it as ‘fallen sky stone’ and many domed roofs in Iran are sheathed in turquoise symbolizing ‘heaven on earth’. Bright sky blue with no inclusions, and consistent color is highly prized. Turquoise gets its name from a French translation of Pierre tourques meaning stone from Turkey. Turquoise is a cryptocrystalline mineral that very rarely forms in a crystal shape. It is formed over time by the percolating of acidic solutions of weathered minerals and metals like copper, aluminum, and phosphorus. It measures a 6 on the Mohs’ scale, therefore turquoise is a softer stone so is often shaped into cabochons, beads and extensively used in inlay.
Turquoise was one of the first stones to be mined, Turkey and Persia (now Iran) were traditional sources of European turquoise. These sources are now depleted and only mined seasonally by small family ventures. The larger deposits of commercial turquoise are found in the southwest of the US, primarily, Nevada, Arizona and New Mexico. Different colors and qualities are produced in each area, leading to distinct types of turquoise names, Kingman, Sleeping Beauty, or Bisbee. Arid regions are associated with turquoise deposits; mines exist in China, Afghanistan, Australia, Chile, and northern India.
Turquoise has long been associated with treatments applied to enhance the color and durability of the stone. In Egypt the desire for a more durable blue colored material lead to the development of faience, a glaze for pottery and a precursor to glass. Turquoise may be stabilized to enhance lower grade more fractured material and dyed to improve the color. Simple oiled or waxed treatments are considered acceptable since it has a very low impact on the stone. Reconstituted material, ground fine then added to resin and re-cut after hardening is the lowest grade. Synthetic Gilson turquoise from the 1970’s is even collectible!

Using Turquoise in your jewelry designs-
Depending on the color of turquoise chosen there are many stones that work well with the blue-green color stones. Native Americans mix turquoise with other opaque stones, like coral, malachite, onyx, sugilite, and lapis. The most common metal for mixing with turquoise is silver, both bright and oxidized. Bright blue stones would be striking wire wrapped on gold wire, or mixed with pyrite, golden pearls or amber. Olive green or heavily veined beads would lovely added to a darker brown stone like tiger’s eye.
