About this 1.53ct natural round diamond

This 1.53ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI 613373467. Listed at 13 retailers as of November 2, 2026, with a relatively tight 17% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
