About this 1.25ct natural round diamond

This 1.25ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 5232753757. Listed at 9 retailers as of November 3, 2026, with a relatively tight 19% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
