Buying or selling diamonds effectively requires a strong understanding of the "4Cs" (Cut, Color, Clarity, and Carat), a reliable lab grading report, and choosing the right platform for the transaction. Key Diamond Evaluation Factors (The 4Cs)
Before buying or selling, you must understand the four primary metrics that determine a diamond's value:
: Graded on a scale from D (colorless) to Z (light yellow). Higher grades (colorless) are significantly more valuable.
: Determines how a diamond interacts with light. An "Excellent" cut grade can add up to a 30% premium to the value.
: Measures internal and external flaws (inclusions and blemishes). Diamonds in the VS1-VS2 range often provide the best balance of visual quality and price. Essential Documentation Natural Diamonds | Diamond Stone – GIA C
: Refers to the stone's weight, not necessarily its physical size. Larger stones are rarer and command higher prices.
