Gemstones with SG 1.05
1 gemstone have a specific gravity range that includes 1.05. 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 |
|---|---|---|---|---|
| Amber | 1.05 – 1.09 | 1.539 – 1.545 | Amorphous | 2–2.5 |
