The first step in understanding jewelry is to understand the language of jewelry, which is the term for gems. When buying or appreciating beautiful jewelry, not only can you better understand the characteristics of gems, but also let you make the best choice when buying.

When discussing gemstones, we usually separate diamonds from other gemstones. The gemstones other than diamonds are called Color Stones, mainly because diamonds have a set of strict and strict identification and grading standards, which are different from other gemstones. Different, so both the jewelry industry and gemology circles use this as a division.

Refractive Index

The refractive index of a gemstone is calculated from the relative velocity ratio of the light beam entering the interior of the gemstone from the air. The calculation method is that the speed of light in the air divided by the speed of light in the gemstone is therefractive index”. If a gemstone is bent at one angle, it is called “single refraction”, and if it is bent at two angles, it is called “birefringence”. The difference between the two refractive index values ​​is called “birefringence”.

Toughness

It refers to the degree to which a gemstone can withstand impact and breaks. One point to be clarified is that toughness and hardness are two distinct characteristics in gemology. Whether a gemstone is fragile depends on its toughness and hardness. It is irrelevant. Dus, whether a gemstone is easily damaged or broken when it is hit by an external force or dropped is mainly determined by its toughness rather than its hardness. The classification of toughness is divided into five grades, from good to bad in order: Exceptional, Very Good, Goed, Fair, Poor. Nephrite jade has the highest toughness among all gems. Because of its interlocking structure, it can withstand considerable impact without breaking. The diamond with the highest hardness ranks behind this gem.
