About this 3.5ct natural round diamond

This 3.5ct natural round sits in the three to five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 6561206375. Listed at 6 retailers as of November 2, 2026, with a relatively tight 4% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
