Summary
Jade has been widely utilized in the ancient cultures throughout the human history.
Geologically, jade refers to two different kinds of minerals – ‘jadeite’ and
‘nephrite’, which have different composition, appearance, and properties. Both
‘jadeite’ and ‘nephrite’ are valued for their beauty, mystique, and romance all over
the world.
Although jade has been highly regarded in the jewellery industry, its mineralogy,
geological occurrence, and formation are not fully understood. As a consequence,
a number of other green-coloured minerals have been marketed under the name
‘jade’ but are neither a ‘jadeite’ nor ‘nephrite’.
This presentation will discuss the geological origin of ‘jadeite’ and ‘nephrite’.
General knowledge on how to identify and evaluate jade will be covered as well.
Hand specimens of ‘jadeite’ and ‘nephrite’ will be provided for appreciation.
Prior booking is not required; this talk is free of charge for all society members
and non-members.
CPD certificates will be available for those working towards chartership (free for
society members, $20 for non-members).
