Heat Treatment To Gemstones - Black Stone To Green Zircon

Green Zircon Heat Treatment And Geuda Heat Treatment. Gemstone Heat Treatment** and *Geuda Heat Treatment* are processes used in the gem industry to enhance the color and clarity of gemstones. Here’s an explanation of both: Gemstone Heat Treatment** Heat treatment is a common process used in the gemstone industry to improve the color and clarity of certain gemstones. The heat treatment process involves exposing the gemstones to high temperatures in controlled environments, which can bring out more vibrant colors and remove certain inclusions or imperfections. Common Gemstones Treated with Heat:** **Sapphires**: Heat treatment is commonly used to enhance the color of sapphires, particularly blue sapphires. It can intensify their blue color or remove any secondary hues like green or brown. **Rubies**: Similar to sapphires, rubies can be heat-treated to improve their color and clarity. **Amethysts**: Heat treatment can turn lighter amethyst stones into deeper, more intense purple colors. **Topaz**: Often treated to enhance its blue hues, as well as to remove any brownish tones. **Tourmaline**: Heat can be used to enhance the color and eliminate any unwanted hues in tourmaline stones. How Heat Treatment Works:** **Temperature Range**: Gemstones are heated to temperatures between 400°C and 1800°C, depending on the type of stone and the desired result. **Duration and Method**: The time and method of heating can vary—some gemstones are heated in an oven, while others may be exposed to natural or synthetic heating methods. Ethical Considerations:** Heat treatment is widely accepted in the gem industry as a standard and non-deceptive practice. However, it is important for gem dealers to disclose any heat treatments to buyers so they can make informed decisions. --- Geuda Heat Treatment** *Geuda* refers to a type of *light-colored sapphire* or *sapphire rough* that has poor transparency and is often not very attractive in its natural form. Geuda stones are typically mined in Sri Lanka, and they are known for their milky or cloudy appearance, which makes them less valuable in their untreated state. Geuda Heat Treatment Process:** **Purpose**: The main goal of heating geuda stones is to improve their color and clarity. By subjecting the geuda stones to heat treatment, it is possible to enhance their blue color, reduce cloudiness, and improve overall transparency. **Transformation**: After heat treatment, geuda stones can often resemble higher-quality sapphires. The heat helps bring out a more vibrant, appealing blue color and improve their clarity, making them more marketable as sapphires. **Impact on Value**: Geuda stones that undergo heat treatment can sometimes be transformed into gemstones with similar appearance and value to higher-grade sapphires, which are sold at much higher prices than untreated geuda. *Why Geuda Treatment is Common:* Geuda sapphires have a relatively low market value in their untreated state. Heat treatment allows these stones to be "upgraded" and turned into more valuable gemstones, making them more desirable for both jewelry makers and collectors.
