Rough turquoise refers to the natural, uncut form of turquoise, a highly prized gemstone that has been used in jewelry and ornamental objects for centuries. Here are some key features of rough turquoise:

1. Color: Turquoise is known for its distinctive blue to green-blue color, often with a matrix of darker veins or inclusions. The color can vary depending on the presence of copper or iron compounds.
2. Formation: Turquoise is a hydrated phosphate mineral and is typically formed in arid regions where water interacts with copper and aluminum minerals. It often occurs in veins or nodules in host rocks.
3. Hardness: Turquoise has a moderate hardness of 5 to 6 on the Mohs scale, making it relatively soft compared to some other gemstones.
4. Matrix: The matrix in turquoise refers to the host rock or other minerals present in the stone. Black, brown, or golden-colored matrix patterns are common in turquoise, and they can add to the stone’s unique appearance.
5. Transparency: Turquoise is usually opaque, though some higher-grade specimens may exhibit translucency.
6. Locations: Turquoise is found in various locations around the world. Some well-known sources include the United States (especially Arizona and New Mexico), Iran, Afghanistan, China, and Mexico.
7. Uses: Rough turquoise is often cut and shaped into cabochons, beads, or carved into various forms for use in jewelry. It has been historically used in Native American jewelry, as well as in other cultural and contemporary designs.
8. Stabilization: Turquoise is often treated to enhance its stability and color. Stabilization involves impregnating the stone with a clear resin to strengthen it and prevent color change.

When purchasing rough turquoise or turquoise jewelry, it’s important to consider factors such as the color, matrix patterns, and the presence of any treatments. Authenticity and ethical sourcing are also crucial considerations when acquiring turquoise specimens.
