Characteristics of GGG crystal：

GGG (Gd₃Ga₅O₁₂) is a synthetic cubic crystalline gemstone material with the following characteristics:

1. Optical performance: refractive index 1.97 (close to 2.42 of diamond), dispersion value 0.045, showing a strong fire color effect

2. Hardness: Mohs hardness 6.5-7, suitable for daily wear jewelry production

3. Density: 7.09g/cm³, with heavy texture

4. Color: The system is colorless and transparent, and a variety of tones can be obtained by doping

Advantages of GGG crystals：

1. Brightness: Better than cubic zirconia (CZ), closer to the optical effect of diamond

2. Stability: High temperature resistance (up to 1200℃), not easy to oxidize and discolor

3. Machinability: 57-58 facets can be cut perfectly to show the best optical effect

4. Cost performance: The cost is only 1/10-1/20 of the same quality diamond

Jewelry field:
