About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a top-tier cut grade and certified by GIA 7378126089. Listed at 3 retailers as of November 3, 2026, with a relatively tight 6% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
