Persian Turquoise: The Timeless Gemstone

Turquoise, with its unique blue-green hues and rich history, has captivated people for centuries, especially in turquoise pendant jewelry. Cherished by various cultures including the Aztecs, Egyptians, and Native Americans, its stunning colour comes from copper in its composition, making each piece truly one-of-a-kind in different colours. The name ‘turquoise’ is derived from the French term for ‘Turkish stone,’ as early imports to Europe came through Turkey. To preserve its vibrant color, it is advisable to store turquoise jewelry away from direct sunlight, as prolonged exposure can lead to fading.

Value and Color Range

The most valuable turquoise stones are bright blue with no spots or streaks, with even color saturation. Turquoise's blue-green color ranges from sky blue to greenish-blue to pale green or greenish-grey, adding to its diverse appeal.

Historical Significance

Turquoise was one of the first gemstones ever mined and was prized for its intense color. Turquoise is relatively soft, registering 5-6 on the Mohs scale, which makes it more prone to scratches and requires careful handling.

Color Changes Over Time

Over time, Turquoise can change color due to its porous nature, absorbing oils and other substances, which adds to its dynamic and evolving character.

Origin of the Name

The name ‘turquoise’ is derived from the French term for ‘Turkish stone,’ as early imports to Europe came through Turkey. The term itself originates from "pierre tourques," which translates to "Turkish stone," reflecting its historical trade routes.

Unique Characteristics

Unlike diamonds, Turquoise is appreciated for its natural state and unique matrix patterns, adding to its charm and individuality. Generally, bluer turquoise stones are considered more valuable due to higher copper content, which contributes to their striking and vivid appearance. Turquoise is opaque, as opposed to translucent, unlike many other gems, which further distinguishes it in the world of gemstones. For instance, copper turquoise jewelry combines the allure of turquoise with the vibrance of copper, creating unique and stylish pieces.

Mining History and Cultural Importance

Turquoise has been mined for over a millennium, with notable historical regions such as Iran, particularly Nishapur. Its cultural significance and timeless beauty make it a prized gemstone in the gemstone world, perfect for adding history and spirituality to any collection.
