Turquoise, with its mesmerizing hues ranging from sky blue to deep green, has been cherished for millennia. It’s not only a stone of beauty but also a symbol of protection, healing, and wisdom. Whether you’re a collector, a jewelry enthusiast, or someone looking for the perfect turquoise piece, this guide will help you navigate the intricate process of choosing the right turquoise gemstone.
1. Understanding the Value of Turquoise
Before diving into the selection process, it’s important to understand what makes turquoise valuable. Several factors contribute to its value:
- Color: The most prized turquoise color is a vibrant, robin’s egg blue, often referred to as “Persian blue.” However, turquoise also comes in shades of green and even yellow-green. The color you choose will largely depend on your personal preference.
- Matrix: The matrix is the host rock that turquoise is found in, often visible as veins or patterns within the stone. Some prefer a clean, matrix-free turquoise, while others appreciate the intricate patterns that a matrix provides. The spiderweb pattern is particularly sought after.
- Origin: Turquoise from certain regions is considered more valuable. For instance, Persian turquoise is highly regarded for its pure blue color, while American turquoise from mines in Arizona and Nevada is known for its variety of colors and unique matrices.
- Treatment: Natural turquoise, which has not been treated in any way, is the most valuable. However, many turquoise stones are stabilized (treated to enhance durability) or dyed to improve color. It’s crucial to know whether the turquoise you’re purchasing has undergone any treatment, as this will affect both its value and care requirements.
2. Assessing Turquoise Durability
Turquoise is a relatively soft gemstone, with a Mohs hardness rating of 5 to 6. This means it can be easily scratched or damaged if not handled properly. When choosing turquoise for everyday wear, such as in rings or bracelets, consider the following:
- Natural vs. Stabilized: Natural turquoise is more susceptible to damage, while stabilized turquoise has been treated to improve its hardness and resistance to wear. If you plan to wear your turquoise frequently, stabilized stones might be a better option.
- Setting: The setting of your turquoise jewelry can also impact its durability. Bezel settings, which encase the stone, offer more protection than prong settings, which leave the stone more exposed.
3. Selecting the Right Size and Shape
Turquoise is available in a variety of sizes and shapes, each offering a different aesthetic. The choice of size and shape will depend on your personal style and the type of jewelry you’re purchasing.
- Cabochon: The most common cut for turquoise is the cabochon, a smooth, rounded shape that highlights the stone’s color and matrix. Cabochons are perfect for rings, pendants, and earrings.
- Carat Weight: Turquoise is typically sold by the carat, but unlike diamonds, the carat weight doesn’t significantly affect its value. Instead, focus on finding a stone that fits the design and scale of the jewelry piece you have in mind.
- Custom Shapes: For a more unique piece, consider custom shapes or cuts, such as teardrop, oval, or freeform. These can add a distinctive flair to your jewelry.
4. Ensuring Authenticity
With the popularity of turquoise, there are unfortunately many imitations and treated stones on the market. Here are some tips to ensure you’re purchasing genuine turquoise:
- Buy from Reputable Sources: Purchase from well-known jewelers or dealers who specialize in gemstones. They should provide information about the stone’s origin, treatment, and authenticity.
- Request Certification: Ask for a certificate of authenticity, especially for high-value turquoise. This certificate should detail the stone’s origin, any treatments it has undergone, and its overall quality.
- Physical Examination: Genuine turquoise will have a waxy, smooth feel and a weighty presence. If the stone feels too light or too glassy, it may be an imitation or treated stone.
5. Caring for Your Turquoise
Once you’ve chosen your turquoise gemstone, proper care is essential to maintain its beauty and longevity:
- Avoid Chemicals: Turquoise is porous and can be damaged by exposure to chemicals, including cosmetics, perfumes, and household cleaners. Always remove turquoise jewelry before applying any products.
- Clean Gently: Use a soft, damp cloth to clean your turquoise. Avoid using ultrasonic cleaners or harsh cleaning solutions, as they can damage the stone.
- Store Properly: Store turquoise separately from other gemstones to prevent scratches. A soft pouch or a lined jewelry box is ideal.
6. The Spiritual and Cultural Significance of Turquoise
Turquoise isn’t just a beautiful stone; it also carries deep spiritual and cultural significance:
- Healing Properties: Many believe that turquoise has healing properties, promoting mental clarity, emotional balance, and physical well-being.
- Cultural Symbolism: In many cultures, turquoise is seen as a protective stone, warding off evil and bringing good fortune. Native American cultures, in particular, have a rich history of using turquoise in ceremonial and everyday items.
Choosing the right turquoise gemstone is a deeply personal process that combines aesthetic preference with an understanding of the stone’s qualities and value. Whether you’re drawn to its vibrant color, unique patterns, or cultural significance, choosing the right turquoise gemstone is an experience that can result in a cherished piece for a lifetime. By following the tips in this guide, you can confidently focus on choosing the right turquoise gemstone that resonates with you and stands the test of time.
