Gemstone Treatments
Gemstone treatment refers to any process applied to enhance the appearance, durability, or color of a gemstone. These treatments can vary widely depending on the type of gemstone and the desired outcome. Treatments are widely accepted within the jewelry industry. Today, most gems are treated to improve appearance.
Common gemstone treatments include:
-
Heat Treatment: One of the most widely used treatments, heat treatment involves heating a gemstone to high temperatures to enhance its color and clarity. This process can remove or reduce unwanted colors, improve clarity by dissolving internal inclusions, and enhance the overall appearance of the gemstone. Heat treatment is commonly used for gemstones such as sapphires, rubies, and citrine.
-
Irradiation: Irradiation involves exposing a gemstone to radiation to alter its color. This treatment can produce a wide range of colors, including blue, green, and pink, in gemstones such as diamonds, topaz, and quartz. Irradiated gemstones are typically stable and safe to wear, but disclosure of treatment is required in the jewelry industry.
-
Fracture Filling: Fracture filling is a treatment used to improve the clarity of gemstones by filling surface-reaching fractures or cavities with a glass-like substance. This process can enhance the gemstone's appearance by reducing the visibility of inclusions and improving its overall clarity. Fracture-filled gemstones are often treated with caution and should be disclosed to consumers.
-
Surface Coating: Surface coating involves applying a thin layer of color or luster-enhancing material to the surface of a gemstone. This treatment can enhance the gemstone's color, add a reflective coating, or create unique visual effects. Surface-coated gemstones should be disclosed to consumers, as the coating may wear off over time.
-
Dyeing: Dyeing is a treatment used to alter or enhance the color of a gemstone by immersing it in colored solutions or dyes. This process can produce a wide range of colors and effects in gemstones such as pearls, jade, and coral. Dyed gemstones should be disclosed to consumers, as the color may fade or change over time.
