"Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds" - GIA
We all love diamonds, we thought we would explain them a little further...
The CLARITY of a Diamond refers to its optical quality. Grading of Clarity is based on the size, number and position of any internal or external flaws or imperfections, using a standard Clarity Grading system.
The CUT or 'make' of a Diamond refers both to its Shape and its Facet Style. The Quality of the Cut essentially determines the Light Performance of a Diamond and can have the greatest effect on its value.
The COLOUR in Diamonds ranges from totally Colourless through a progression of tinted and lighter colours to fully saturated Fancy Colours. In Colour grading the Yellow or Cape Series is used as a basic standard.
The word CARAT comes from the ancient Greek name for the Carob Seed (Keration) which, due to its consistent size and weight, was once widely used as a counterweight for weighing Diamonds and Gemstones.
