WHAT IS A GEMSTONE?

Rough materials are cut and polished. They are classified into differents Groups, Species and Varities. GEMSTONES are characterized in terms of:

REFRACCION INDEX, DISPERSION, SPECIFIC WEIGHT, HARDNESS, CLEAVAGE AND FRACTURE.

The value and beauty of a gemstone can be determined for these characteristics first.

The traditional distinction Precious, Semiprecious does not reflect modern values. A Red Beryl, ( rare gemstone ) or a Pink Tourmaline, for example, can be far more valuable than a poor quality Ruby.
