GGG synthetic gemstones Gd₃Ga₅O₁₂ Gadolinium gallium garnet amber color Custom Jewelry
Gadolinium Gallium Garnet (GGG), with the chemical formula Gd3Ga5O12, is a synthetic gemstone characterized by its glassy to subadamantine luster and homogeneous nature. It exhibits a Mohs hardness ranging from 6.5 to 7.5 and a density of approximately 7.05 g/cm³. GGG is utilized as a diamond substitute due to its unique optical properties and color options, and it continues to be employed in certain high-end bespoke jewelry designs as an alternative gemstone.
GGG gemstones features
1. High melting point and thermal stability: The melting point of GGG crystal is about 1750°C, which has excellent thermal stability and is suitable for application in high temperature environment.
2. Excellent mechanical properties: high hardness (Mohs hardness about 7.5) and good mechanical strength, can withstand the mechanical stress in processing and use.
3. Chemical inertness: Good chemical stability for most acids, bases and solvents, suitable for corrosive environments.
4. Lattice matching: Its lattice constant is highly matched with a variety of functional materials (such as yttrium iron garnet YIG), which is an ideal substrate for high-quality epitaxial growth.
GGG gemstones application
GGG crystals (gadolinium gallium garnet) have unique advantages in the field of gemstone materials, because of their high refractive index (about 1.97), excellent optical transparency and rich color expression, and are often used as high-end imitation stones. The following are the main applications of GGG crystals in gemstone materials:
1. Imitation of natural gems: GGG crystals can perfectly simulate the gloss and fire color of natural gems such as diamonds and sapphires, and the cost is lower, suitable for making high-end fashion jewelry. Its high refractive index and dispersion properties give the gemstone a brilliant visual effect in light.
2. Colored gems: By doping different elements, GGG crystals can show a variety of colors (such as green, pink, blue, etc.) to meet the diverse needs of jewelry design. Its high color saturation is suitable for making personalized jewelry.
3. High durability jewelry: The hardness of GGG crystal (Mohs hardness of about 7.5) is close to natural garnet, strong wear resistance, suitable for making daily wear rings, earrings and pendants and other jewelry.
4. Customized design: GGG crystals are easy to cut and polish, enabling complex design requirements and providing unique customization options for high-end jewelry brands.
