3 Carat Marquise Cut D Color Lab Grown Diamonds

D is the highest color grade, completely colorless. At 3 carats, D is especially valuable in a marquise because both pointed tips can concentrate color at lower grades. D ensures absolute colorlessness from tip to tip across this dramatic, elongated shape.

More important than for round brilliants. The marquise's pointed tips concentrate color, and at 3 carats, this effect is amplified. D eliminates all concern about tip-color concentration. However, the brilliant faceting helps mask color, so E-G grades also perform well.

A 3 carat D marquise lab diamond looks best in solitaire settings with V-prongs at each point, bezel settings, and halo designs. At 3 carats, the stone has significant presence, so a simpler setting lets the diamond take center stage. With D color (colorless), only detectable by trained gemologists with master stones. The two pointed ends need v-prongs for protection, and symmetry between the two halves is essential.
