Gemmology is the fascinating study of all types of gem materials –  natural, lab grown and imitation.  Gems come from every corner of the  planet and touch almost every culture in the world.  Gemmology Basics is for the student who is launching their career into the world of  jewellery fashion or gem trading, or; for the avid collector who wants to know more; or even for the person who works in a jewellery store who wants to be able to answer customer’s questions; for a budding  appraiser; and finally to the goldsmith who wants to know the physical properties of the gems they
are setting.
