GIA Certified Diamonds

What is GIA?

GIA stands for Gemological Institute of America, which is a non-profit organisation that is widely regarded as the world's foremost authority on diamonds, coloured stones, and pearls. Founded in 1931, GIA is a leader in gemological research, education, and certification, with a mission to ensure public trust in gems and jewellery.

Understanding the 4 Cs

The "4 Cs" of a diamond refer to its carat weight, cut, colour, and clarity. These are the four characteristics that the GIA (Gemological Institute of America) uses to evaluate and grade diamonds.

Carat Weight: This refers to the weight of the diamond, measured in carats. One carat is equivalent to 0.2 grams, and the weight of a diamond can greatly affect its value.

Cut: This refers to the diamond's proportions, symmetry, and polish, which all influence its ability to reflect light and sparkle. A well-cut diamond will have maximum brilliance, fire, and scintillation.

Colour: This refers to the presence or absence of colour in a diamond. The GIA grades diamonds on a scale from D (colourless) to Z (light yellow or brown). The less colour a diamond has the higher its value.

Clarity: This refers to the presence or absence of internal (inclusions) or external (blemishes) imperfections. The GIA grades diamonds on a scale from Flawless (no inclusions or blemishes visible under 10x magnification) to Included 3.
