About this 1.31ct natural round diamond

This 1.31ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6492761584. Listed at 14 retailers as of October 30, 2026, with a relatively tight 17% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
