Genuine Emeralds from earth
Many people expect a specific answer from this question, however, the process of developing an emerald in nature is not well known, since it depends on many variables to have this data accurately.
Some experts estimate that it may take up to 100,000 years to fully develop an emerald, however, other scientists wonder if it really takes so long.
Scientists claim that laboratory-made crystals can grow in a year, then they assume that it is possible for emeralds to grow on a real time scale, only if they meet the perfect conditions.
| Chemical Formula | Be3Al2SiO6 |
| Colour | Green |
| Hardness | 7.5 – 8 |
| Crystal System | Hexagonal |
| Refractive Index | 1.57 – 1.58 |
| SG | 2.6 – 2.8 |
| Transparency | Transparent to translucent |
| Double Refraction | 0.006 |
| Luster | Vitreous |
| Cleavage | 3,1 – basal |
| Mineral Class | Beryl (Emerald) |
Despite these scientific assumptions, there is no doubt that some emeralds are very old. Some deposits date back only twenty million years ago, while others date back two billion years ago. The only thing known is that the emerald is a very old and beautiful Rock.
