DIAMOND CUTTING PROCESS
Not to be confused with the shape of a diamond, cut refers to the arrangement of a diamond’s facets. Cut is the most important of the 4C’s and is the only “C” under man’s control.
Using an exacting mathematical formula, master cutters create ideal cut diamond for 100% light refraction.
All light beams should be refracted up to the viewer's eye as shown in the 'ideal' sketch in the diagram as opposed to 'shallow' and 'deep' cut allowing light beams to travel out of the stone.
The result: unparalleled beauty and grace, maximizing the coveted diamond characteristics of brilliance, scintillation and fire.
DIAMOND COLOR GRADING
Color is determined by viewing the body of the diamond from the side with the table down and proper lighting.
Pure colorless diamonds are classifies as "D" and the color scale ranges alphabetically from D-Z.
Diamonds range from colorless - the rarest and most valuable - to various degrees of yellow.
COLORLESS: D, E, F
NEAR COLORLESS: G, H, I, J
FAINT YELLOW: K, L, M
VERY LIGHT YELLOW: N, OP, QR
LIGHT YELLOW: ST, UV, WY, YZ
DIAMOND CLARITY GRADING
Clarity is the degree to which identifying characteristics known as inclusions are present in a diamond.
FLAWLESS; Internal Flawless No inclusions visible under 10x magnification
VVS, VVS1, VVS2: Very Very Slight Inclusion Inclusions are minute, extremely difficult to locate under 10x magnification
VS, VS1, VS2: Very Slight Inclusion Inclusions are minor, difficult to locate under 10x magnification

CARAT-WEIGHT
Carat weight is a standard unit of weight used for gemstones. A diamond s weight is the easiest of the 4C's to measure.
One carat is equal to 200 milligrams. Carat weight can be expressed as a decimal, fraction, or in "points." There are 100 points in a carat. A 50-point diamond is 1/2 a Carat.
