About this 1.3ct natural round diamond

This 1.3ct 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 6555978872. Listed at 16 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.
