Gemstones with SG 5.85
2 gemstones have a specific gravity range that includes 5.85. 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 |
| Cuprite | 5.85 – 6.15 | 2.849 – 2.849 | Cubic | 3.5–4 |
