Knowledge of type allows gemmologists to better evaluate if a diamond might be treated or synthetic, and whether it should be sent to a laboratory for testing.
Read MoreThis article discusses the history and ongoing development of GIA's colour grading system, and explains how its laboratory applies it.
Read MoreHigh-quality CVD-grown diamonds, comparable in colour and clarity to natural diamonds, can be identified using a combination of gemmological and spectroscopic properties.
Read MoreHistorically, global rough diamond production has fluctuated greatly due to a myriad of causes, many of which are explored in this article.
Read MoreThe GIA diamond cut grading system described here includes the components of brightness, fire, scintillation, polish and symmetry, as well as weight and durability concerns, into a single overall grade for cut quality for standard round brilliants.
Read MoreA simplified form of X-ray topography can fingerprint faceted diamonds to aid in their recovery from loss or theft.
Read MoreThe 1990s witnessed important developments in the commercial viability of gem-quality synthetic diamonds.
