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 2547180782. Listed at 8 retailers as of October 30, 2026, with a relatively tight 13% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
