1 gemstone have a specific gravity range that includes 4.95. 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 |
|---|---|---|---|---|
| Hematite | 4.95 – 5.30 | 2.940 – 3.220 | Trigonal | 5.5–6.5 |
