Common Gemstone Treatments

In the gemstone industry, various treatments are applied to enhance the appearance, durability, or even change the color of gemstones. Understanding these treatments is crucial for gemstone enthusiasts, buyers, and professionals, as they can significantly affect the value, care, and understanding of a gemstone. Here are some of the most common treatments used:

Heat Treatment: One of the oldest and most common methods of gemstone enhancement, heat treatment is used to improve or change the color of gemstones. For instance, it can intensify the blue in sapphire, deepen red in ruby, or improve the clarity of diamonds. The effects are usually permanent, but high temperatures can sometimes weaken the structure of the stone.

Irradiation: This treatment involves exposing the gemstone to radiation to alter or enhance its color. Blue topaz, for instance, often undergoes irradiation to achieve its vibrant blue hue. The color change can be permanent, but some irradiated stones may fade over time when exposed to sunlight.

Oil and Resin Filling: Commonly used in emeralds, this treatment fills cracks or fractures in the stone with oil or resin, improving its clarity and overall appearance. These fillings can be affected by heat or chemicals, so treated stones require careful handling and cleaning.

Dyeing: Dyeing is often used to enhance or change the color of porous gemstones like jade, agate, or turquoise. The dye can penetrate the entire stone or just the surface, depending on the material and the process. Dyeing is not always stable, and the color may fade or change over time.

Diffusion Treatment: This treatment involves adding chemicals to the surface of the gemstone and then applying heat, allowing the added elements to penetrate the stone and change its color. Sapphire is commonly treated this way to achieve certain colors. The depth of color penetration varies, which can affect the stone’s appearance if it’s chipped or recut.

Laser Drilling and Fracture Filling: Used primarily in diamonds, laser drilling removes inclusions, and fracture filling hides cracks. The drilling creates tiny channels to the inclusion, which is then removed by chemicals. Fracture filling involves injecting a glass-like substance into cracks to improve clarity. These treatments are detectable under magnification and may affect the stone’s durability.

Bleaching: Bleaching lightens or removes color and is often used on materials like pearls and jade. The process involves chemicals and can be followed by dyeing to achieve the desired shade.

Coating: Applying films or coatings to the surface of gemstones can alter their color, luster, or iridescence. This treatment is more common in lesser-quality stones and can wear off with time or cleaning.

Implications of Gemstone Treatments

• Disclosure: Ethical practices require the disclosure of any treatments a gemstone has undergone, as they can affect its value and care requirements.
• Care and Maintenance: Treated gemstones may require special care to maintain their appearance and longevity. Exposure to heat, light, chemicals, and even ultrasonic cleaners can adversely affect treated stones.
• Valuation: Treated gemstones typically have a lower value compared to untreated ones of the same quality, as natural stones are rarer and more sought after.

Treatments are a significant aspect of the gemstone industry, enhancing the beauty and appeal of gemstones but also necessitating informed handling and valuation. Knowing about these common treatments helps buyers and enthusiasts make educated decisions and appreciate the craftsmanship involved in gemstone enhancement.
