About this 3.51ct natural radiant diamond

This 3.51ct natural radiant sits in the three to five carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1499914670. Listed at 3 retailers as of October 31, 2026, with a relatively tight 14% spread, which is unusual at this carat range and suggests competitive pricing across the listings. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
