3 Carat Heart Cut D Color Lab Grown Diamonds

D is the highest color grade, completely colorless. At 3 carats, D ensures the heart's distinctive silhouette sparkles with pure white light across both lobes and the pointed bottom. The larger face-up area makes D's purity especially impactful.

The heart's brilliant faceting provides good color masking. D is a premium choice for maximum colorless certification at this dramatic size. E-G grades look nearly identical in everyday wear. D matters most for buyers who want the absolute highest grade on their certificate.

Yes, Do Amore offers 3 carat D color heart cut lab grown diamonds, all grown, cut, and polished using renewable energy (solar and hydro power). Every lab diamond comes with certification from the GIA, IGI, or GCAL. Every purchase funds clean water access for one person in need. All rings include free lifetime maintenance covering inspections, polishing, cleaning, stone tightening, rhodium plating, and resizing.

The difference between D and E color is virtually impossible to detect with the naked eye in a heart cut, especially since brilliant-cut faceting masks subtle color differences. Once set in a ring, both grades appear equally white. E color offers savings compared to D with no visible compromise in a 3 carat stone.
