What is Gemmology?

Gemmology is the study of gem materials from their origins through to their use in jewellery - this includes their formation (within the Earth, laboratory, factory or farm), mining or manufacture, treatments, cutting & polishing through to jewellery design. 

A gemmologist uses their knowledge of the individual characteristics of different gemstones to identify them & to determine whether they are natural, synthetic or treated.

There are around 200 gem species, each of which may have a number of different varieties.  For example, Beryl is a species of gemstone which includes the varieties emerald, aquamarine, heliodor, morganite and goshenite.  As you can see, this multiplies up to a large number of different natural gemstones!

Gemmologists also need to keep up to date with the latest treatments, synthetic & imitation stones as they appear on the market.

Gemmology is used in various fields & for a number of purposes, including

  • gemstone mining

  • lapidary (a highly skilled craftsperson who cuts & polishes coloured gemstones)

  • buying & selling gems

  • designing gem-set jewellery 

  • valuation & appraisal of jewellery
