About this 1.2ct natural round diamond

This 1.2ct natural round sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6562100518. Listed at 25 retailers as of October 31, 2026, with a relatively tight 24% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
