Diamond Qualities & Grading Essentials
Understanding the 4Cs of Diamonds
Cut: Brilliance, Proportions & Light Return
Cut determines how light interacts with the diamond — a well-cut diamond will dazzle and draw the eye.
Colour: D-to-Z Grading Spectrum
Colour grading indicates how colourless (or not) a diamond is — the closer to colourless, the more pristine and luminous the diamond.
Clarity: Inclusions & Blemish Types
Clarity reflects internal and surface characteristics — diamonds with fewer inclusions appear clearer and more brilliant.
Carat Weight: Size, Value & Presence
Carat affects size and presence; a larger carat weight often signals rarity and higher value, but good proportions and cut remain essential.
Additional Diamond Attributes
Diamond Fluorescence
Often subtle, fluorescence can influence appearance under certain lights — an attribute worth considering depending on where and when the piece will be worn.
Diamond Proportions, Depth & Table %
Proper proportions affect brilliance and light performance — ensuring your diamond looks balanced and alive under light.
Light Performance & Scintillation
The interplay of cut, proportions, and clarity influences how brilliantly a diamond sparkles and how its flashes of light perform in real life.
