About this 1.26ct natural round diamond

This 1.26ct 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 HRD 260000126192. Listed at 6 retailers as of October 25, 2026, with a relatively tight 11% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
