The 4Cs of Diamonds
At KOAY, every diamond embodies timeless elegance. Guided by the revered 4Cs, we uphold the highest standards of craftsmanship to unveil a brilliance that is pure and everlasting.
Cut
The cut reveals the diamond’s inner light and timeless beauty. With perfect proportions and polish, every facet captures and reflects brilliance in its purest form.
At KOAY, we select only the finest cuts, where true beauty meets perfection.
Color
A diamond’s true beauty lies in the absence of color. Perfectly colorless stones are rare and most prized, while faint yellow or light brown tones appear in lower grades.
At KOAY, we select only diamonds from grades D to J for their pure, refined radiance.
Clarity
Clarity measures a diamond’s purity and rarity by identifying the minute inclusions visible under 10x magnification and evaluating how they affect the stone’s reflection and refraction of light.
At KOAY, our clarity scale includes eleven grades, ranging from Flawless to Included.
Carat Weight
Carat is the standard measure of a diamond’s weight, with one carat equal to 200 milligrams. While carat does not measure size, it can be used to estimate a diamond’s apparent dimensions. Still, two diamonds may share the same weight yet appear entirely different in shape and presence.
