Turquoise is a captivating and versatile gemstone known for its vibrant hues. It primarily comes in shades of blue and green, ranging from sky blue to greenish-blue, often with a matrix of brown or black veining. Understanding the diverse colors of turquoise can enhance your appreciation of this beautiful stone and guide you in selecting the perfect piece for your needs.
What Shades of Blue Does Turquoise Come In?
Turquoise is most renowned for its sky blue shade, often referred to as "robin’s egg blue." This color is highly prized, especially in Persian turquoise, and is considered the most valuable. The blue hue results from the presence of copper in the mineral composition. Here are some common blue shades of turquoise:
- Light Blue: A softer, pastel-like hue that is gentle and calming.
- Medium Blue: The classic, vibrant blue often associated with high-quality turquoise.
- Deep Blue: A rich, intense shade that is less common and highly sought after.
What Shades of Green Can Turquoise Be?
Green turquoise is equally enchanting, though less common than blue. The green color emerges from the presence of iron, which replaces some of the copper in the mineral. Here are typical green shades of turquoise:
- Mint Green: A light, fresh green that is subtle and elegant.
- Apple Green: A brighter, more vivid green that stands out.
- Olive Green: A deeper, earthier shade that is unique and intriguing.
How Does the Matrix Affect Turquoise Color?
The matrix in turquoise refers to the veining or web-like patterns that occur naturally within the stone. These patterns can significantly influence the overall appearance of turquoise. The matrix can be:
- Brown: Often seen in turquoise from the American Southwest, adding an earthy contrast.
- Black: Provides a striking backdrop that highlights the stone’s color.
- Golden: Less common, offering a warm, unique look.
What Factors Influence Turquoise Color?
Several factors affect the color and quality of turquoise:
- Origin: Different regions produce turquoise with distinct colors. For example, Iranian turquoise is famous for its bright blue, while American turquoise often features a greenish hue.
- Mineral Composition: The presence of elements like copper and iron determines whether turquoise is blue or green.
- Treatment: Some turquoise is treated to enhance color and durability, which can alter its natural appearance.
