Turquoise is one of the oldest known gemstones in the world, cherished for its rich history, vibrant color, and natural beauty. Whether you're an avid collector or simply looking for a unique accessory, finding the perfect piece of authentic turquoise jewelry requires a discerning eye and some knowledge about what makes turquoise so special. Here’s a guide to help you navigate the world of turquoise jewelry and ensure that you select a piece that’s both beautiful and genuine.
Understanding Turquoise
Turquoise is a blue-to-green mineral formed by the interaction of copper and aluminum in the earth's crust. The distinctive colors are created by the varying presence of copper (blue) and iron (green), which makes each turquoise stone unique. The quality of turquoise can differ significantly based on its color, texture, and matrix (the host rock in which it is found). Turquoise is often classified by its color (from light blue to deep, rich blue) and the presence of matrix, which can appear as veins or spots of brown, black, or gray within the stone
Color
The color of turquoise is the most significant factor influencing its value. High-quality turquoise tends to have a rich, vibrant color with minimal mottling or matrix. The most prized turquoise colors are deep, pure blues with a smooth, even texture. However, turquoise that leans toward a greenish hue can also be highly valued, especially if it has a rare, desirable shade.
- High-Quality Blue: Turquoise that is a rich, vibrant blue with no discoloration or inclusions is the most sought after. This is often found in famous turquoise mines like the Sleeping Beauty mine in Arizona or the Kingman mine.
- Greenish Turquoise: When turquoise has a greenish tint, it’s often due to the presence of iron in the stone, which can make it just as desirable, depending on the hue and rarity.
- Spiderweb Matrix: Some turquoise stones have a spiderweb matrix (thin veins of host rock), which creates a distinctive look that many find appealing.
Authenticity and Source of the Turquoise
Given the popularity of turquoise, there are many imitations and treated stones on the market. When purchasing turquoise jewelry, it’s essential to know whether the stone is authentic and where it comes from.
- Natural vs. Stabilized Turquoise: Natural turquoise is unaltered, while stabilized turquoise has been treated to enhance its durability and color. While stabilized turquoise is still real, it is generally less valuable than untreated, natural turquoise.
- The Mining Source: Authentic turquoise often comes with details about the mine or region it was sourced from. Notable sources include the United States (Arizona, Nevada, and New Mexico), Iran, and Tibet. Each region produces turquoise with unique characteristics, and some mines (like the Sleeping Beauty mine) are famous for their high-quality blue stones.
Check for Authenticity
Turquoise is a popular gemstone, and unfortunately, there are many imitations and treated stones on the market. When buying turquoise jewelry, make sure you're purchasing authentic turquoise by:
- Asking about the Source: Reputable jewelers should be able to tell you the origin of the turquoise used in their pieces. Many Native American artisans or designers who specialize in turquoise are known for using high-quality, genuine stones.
- Verifying Certification: Some high-quality turquoise jewelry comes with a certificate of authenticity. This is particularly important if you're buying a rare or valuable piece.
- Examining the Stone: Real turquoise typically has a smooth, cool touch and can have natural imperfections, unlike synthetic imitations, which tend to be uniform and perfect in appearance.
Maintenance and Care
While turquoise is a durable gemstone, it does require some care to keep it looking its best:
- Avoid Harsh Chemicals: Turquoise can be sensitive to heat, acids, and harsh chemicals, so avoid exposing your jewelry to perfumes, lotions, and cleaning products.
- Clean Carefully: Clean turquoise jewelry with a soft cloth or a dampened microfiber cloth. Avoid using abrasive materials or harsh cleaning agents, as they can scratch or damage the stone’s surface.
- Store Safely: To avoid scratching, store your turquoise jewelry in a soft-lined jewelry box or pouch. When not wearing it, keep your pieces separate from other jewelry items.
The perfect piece of turquoise jewelry is one that speaks to your personal style, enhances your wardrobe, and holds sentimental or aesthetic value. Whether you're drawn to a piece for its vibrant color, intricate design, or cultural significance, understanding the various types of turquoise, its quality, and how it fits into your overall style will help you make the best choice. By paying attention to authenticity, durability, and design, you’ll find a piece of turquoise jewelry that will be a beautiful and cherished addition to your collection for years to come.
