Turquoise, with its captivating hues ranging from serene blues to vibrant greens, has fascinated cultures for centuries. Its unique blend of color and pattern makes it a highly sought-after gemstone in the world of jewelry and decorative arts. However, before indulging in the allure of turquoise, it’s essential to understand its various types, quality factors, buying considerations, and proper care techniques. In this comprehensive guide, we’ll delve into everything you need to know to make an informed decision when purchasing turquoise.
Types of Turquoise
Natural Turquoise
Natural turquoise is a product of geological processes occurring over millions of years. It forms when water containing copper and aluminum percolates through rocks, resulting in the deposition of turquoise within crevices. The presence of matrix, or veins, is a hallmark of natural turquoise, showcasing its authenticity and natural beauty. This matrix enhances the stone’s character and uniqueness, adding value to each piece. Due to its rarity and natural formation, authentic natural turquoise commands higher prices in the market.
Treated Turquoise
To enhance its durability and color, turquoise often undergoes various treatments. Stabilization involves impregnating the stone with a clear resin to strengthen its structure and prevent discoloration. Enhancement techniques such as dyeing or waxing are used to improve the stone’s color and luster. While treated turquoise may be more affordable than natural specimens, it’s essential to consider the long-term effects of these treatments on the stone’s value and durability.
Reconstituted Turquoise
Reconstituted turquoise is crafted from pulverized turquoise material mixed with binders to form a solid composite. This process creates a more affordable alternative to natural turquoise, albeit with lower intrinsic value. While reconstituted turquoise may resemble its natural counterpart, it lacks the authenticity and rarity associated with natural specimens.
Imitation Turquoise
Imitation turquoise, often made from materials like plastic or dyed howlite, mimics the appearance of genuine turquoise. However, discerning buyers can identify imitation turquoise by examining its texture, color consistency, and lack of natural matrix. Educating oneself on these distinguishing features is crucial to avoid inadvertently purchasing imitation turquoise.
Quality Factors
Color
The color of turquoise ranges from sky blue to deep green, with variations influenced by factors such as copper and iron content. High-quality turquoise exhibits a vibrant, evenly distributed color, free from discoloration or fading. Intense blues and greens are highly prized among collectors and enthusiasts, reflecting the stone’s natural beauty and rarity.
Matrix
Matrix, or veining, refers to the intricate patterns formed by mineral deposits within turquoise. While some prefer turquoise with minimal matrix for a clean, uniform appearance, others appreciate the character and depth provided by prominent matrix. The presence of matrix adds to the stone’s uniqueness and can significantly impact its value.
Clarity
Inclusions, or natural imperfections within the stone, affect its clarity and overall appearance. While some inclusions may be desirable, such as pyrite flecks known as “fool’s gold,” excessive inclusions can detract from the stone’s beauty and value. Evaluating turquoise for clarity involves examining the presence and visibility of inclusions under magnification.
Cut and Polish
The cut and polish of turquoise influence its brilliance, shine, and overall aesthetic appeal. Well-executed cuts enhance the stone’s natural color and allow light to interact with its surface, resulting in a captivating glow. Additionally, expert polishing accentuates the stone’s smooth texture and lustrous finish, elevating its visual appeal.
Buying Considerations
Price and Value
Turquoise prices vary depending on factors such as type, quality, and size. Natural turquoise commands higher prices due to its rarity and authenticity, while treated and reconstituted turquoise offer more affordable alternatives. Buyers should exercise caution when encountering unusually low prices, as they may indicate imitation or low-quality turquoise.
Seller Reputation
When purchasing turquoise, it’s crucial to buy from reputable sources with a track record of honesty and integrity. Established jewelers and dealers provide accurate information about the origin, treatment, and quality of their turquoise inventory. Researching seller reviews and certifications can help ensure a positive buying experience and authentic turquoise products.
Certification
For valuable turquoise pieces, obtaining certification from reputable gemological organizations adds credibility and authenticity. Certificates provide detailed information about the stone’s characteristics, including its origin, treatment history, and quality grade. Buyers seeking assurance of their turquoise’s authenticity and value should consider investing in certified pieces.
Caring for Turquoise
Turquoise is a relatively soft gemstone prone to damage from chemicals, cosmetics, and excessive heat. To preserve its beauty and integrity, follow these basic care instructions:
Avoid exposing turquoise to harsh chemicals, including household cleaners and perfumes, which can cause discoloration and damage.
Remove turquoise jewelry before swimming or bathing to prevent exposure to chlorine and other chemicals present in water.
Store turquoise away from direct sunlight and heat sources to prevent color fading and deterioration.
Clean turquoise gently with a soft, damp cloth to remove dirt and oils, taking care not to scrub or use abrasive cleaners.
Periodically inspect turquoise settings for signs of wear or damage, seeking professional repair if necessary to prevent loss or further damage.
By understanding the types, quality factors, buying considerations, and care techniques associated with turquoise, buyers can make informed decisions and appreciate the timeless beauty of this captivating gemstone. Whether adorning jewelry pieces or adorning decorative items, turquoise continues to enchant and inspire generations with its alluring colors and rich cultural significance.
