Turquoise, also known as Firoza, is a popular semi-precious gemstone known for its vibrant blue-green color. The name “turquoise” is derived from the French word “turquois,” meaning “Turkish,” as the stone was originally brought to Europe from Turkey.
Properties and Characteristics of Turquoise:
- Color: The most desirable turquoise exhibits a unique shade of blue, often with hints of green. The color can range from sky blue to a greenish-blue hue. The intensity of the color can vary, and deeper and more vivid shades are generally considered more valuable.
- Hardness: Turquoise has a relatively low hardness on the Mohs scale, ranging from 5 to 6. This means it can be scratched or damaged more easily compared to harder gemstones like diamonds or sapphires.
