1 gemstone have a specific gravity range that includes 5.65. Specific gravity measures density relative to water — a key diagnostic property for gem identification. Measured by hydrostatic weighing or heavy liquids.
| Gemstone | SG Range | RI Range | Crystal System | Hardness |
|---|---|---|---|---|
| Cubic Zirconia | 5.60 – 6.00 | 2.150 – 2.180 | Cubic | 8–8.5 |
