Presents the underlying physics and methodology of this analytical technique, which has become an essential tool in identifying treated and synthetic diamonds.
Read More
Explores the history, geology and current production of this unique source of large diamonds.

Characterises a suite of 40 natural brown to black diamonds from this deposit so that they can be distinguished from suspected treated black diamonds.
Read More
Summarises data collected on more than 15,000 natural blue/grey/violet diamonds examined by GIA during the last decade and examines the mechanisms that produce this colour range.

Explores an exceptional family of diamonds, referred to as “CLIPPIR” (Cullinan-like, Large, Inclusion-Poor, Pure, Irregular and Resorbed), that formed in a super-deep environment.
Read More
A simple chart of optical defects in diamond, including those that produce colouration and fluorescence colours.
Read More
How variations in UV lamp output can affect observed fluorescence colour and intensity.
Read More
The past decade saw some impressive discoveries of diamonds and coloured stones.
