Gem classification

There are three types of classification for coloured gemstones.

Spinel is a type 2 gem; type 2 gemstones usually have inclusions. If spinel is free of inclusion to the naked eye, the price is higher than visible inclusions.

Our grading standards:

AAA+ Loupe clean

AAA Eye clean (no inclusions visible to the naked eye)

AA Slight inclusions

A Moderate inclusions

B Severe inclusions
