• Radiant: a rectangular brilliant cut that combines the emerald outline with round-style faceting.
• D color: absolutely colorless, the top grade.
• VVS1 clarity: very very slight inclusions, near-impossible to find under 10x magnification.
• Lab-grown: chemically identical to natural diamonds, typically at least 90% less than a comparable natural cohort from 1 carat up.
