CUT

Number of facets, polish, culet size and other characteristics affect the brilliance, fire and scintillation of a diamond. Brilliance refers to the reflection of all white light from the surface and inside of a diamond. It refers to the brightness of a diamond in a lighted environment.

The number of facets affects the proportion of the diamond, which has an impact on its brightness. A diamond’s polish is the degree of smoothness of each facet. Polish affects the reflection of light upon each facet. If the culet is too large, light escapes from the diamond, making it less brilliant.

A diamond’s fire can be better observed in a darker environment. The flashes of colour observed are known as fire. Sparkles in the diamond are known as scintillation. Cut proportion affects the refraction and dispersion of a diamond’s fire and scintillation.

Cut is graded by GIA on a scale of poor to excellent.

CARAT WEIGHT

Carat weight is the unit of measurement for a diamond.
1.00ct = 100 pts
5.00 cts = 1 gm

Due to rarity, as the size of the diamond increases, the price per carat is higher
