About this 0.53ct natural round diamond

This 0.53ct natural round sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by IGI 810626368. Listed at 10 retailers as of November 2, 2026, with a relatively tight 23% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
