Crystal System

Gemstones and minerals are classified into seven primary crystal systems based on their atomic structure.

Refractive Index

The refractive index (RI) of a material measure how much light is bent, or refracted, when entering the material from another medium.

Specific Gravity

The specific gravity (SG) of a substance is a measure of its density compared to water.
