Definition and Description
Turquoise is a semi-precious gemstone known for its unique blue-green color. It’s made of hydrated copper and aluminum phosphates. These minerals form in dry areas where water meets copper salts and aluminum in rocks.
Origin of the Name
The name “turquoise” comes from the French “pierre turquoise,” meaning “Turkish stone.” This is because the gemstone was first brought to Europe through trade with Turkey.
Historical Background and Discovery
Turquoise has a long and interesting history, dating back over 5,000 years. Ancient cultures like the Egyptians, Persians, and Native American tribes valued it. They used it in jewelry, art, and for ceremonies.
This gemstone’s unique look and history have made it important in cultures around the world.
“Turquoise, with its captivating blue-green hue, has been adorning jewelry and artifacts for centuries. This striking stone has a rich history, rich symbolism, and a plethora of intriguing attributes.”
Turquoise is between a 5 and 6 on the Mohr’s Hardness Scale. This means it’s a bit soft but still durable. Many mines are in China, Iran, and the US Southwest (Arizona, New Mexico, California, and Nevada).
The No. 8 mine in Nevada was famous for its spiderweb turquoise. It’s now closed, making these stones very rare and valuable to collectors.
Physical Characteristics of Turquoise
Turquoise is known for its stunning turquoise appearance and turquoise color. These colors range from a soft blue to a bright green.

Another big worry is turquoise discoloration. This happens because turquoise can soak up oils and water, changing its color. It’s also normal for turquoise to turn green over time. This change is natural and doesn’t mean the stone is fake.
It can be tricky to tell real vs fake turquoise. Real turquoise usually has a blue or green color and feels soft. Knowing about these things can help you take better care of your turquoise.

| Green Turquoise | A natural color change that occurs over time as the stone absorbs oils and water, leading to oxidation and a shift towards a greener hue. |

| AAA Turquoise | The highest quality grade of turquoise, characterized by a consistent, even color and a lack of matrix or veining. |

Caring for Turquoise Gemstones
Maintaining the beauty of turquoise gemstones needs careful attention. They are soft and porous, so they need special care. Always remove turquoise jewelry before doing activities that might expose it to water, oils, or other harmful substances.
Chemicals, strong acids, and high heat can damage turquoise. So, be careful with them.
To clean turquoise jewelry, use a gentle method. Mix warm water with mild soap, then wipe it clean with a soft cloth. This keeps the stone safe and clean. Don’t soak turquoise jewelry in cleaning solutions, as it can harm both the silver and the stone.
HARPO, a well-known seller of American turquoise, says to store jewelry in a dry place. Air and humidity can tarnish the silver and change the color of the turquoise. Keep your turquoise jewelry in sealable bags in a cool, dark spot. This way, your jewelry will stay beautiful for a long time.
