Located near the Arctic Circle, Diavik is one of the world’s richest diamond deposits and a leader in sustainable mining.
Read MorePresents the underlying physics and methodology of this analytical technique, which has become an essential tool in identifying treated and synthetic diamonds.
Read MoreExplores the history, geology and current production of this unique source of large diamonds.
Read MoreCharacterises a suite of 40 natural brown to black diamonds from this deposit so that they can be distinguished from suspected treated black diamonds.
Read MoreSummarises 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.
Read MoreExplores 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 MoreA simple chart of optical defects in diamond, including those that produce colouration and fluorescence colours.
Read MoreHow variations in UV lamp output can affect observed fluorescence colour and intensity.
Read MoreThe past decade saw some impressive discoveries of diamonds and coloured stones.
Read MoreA new microlithography process developed to create high-resolution diffraction grating patterns on portions of certain facets can improve the dispersion of light and thus the amount of “fire” in a diamond.
