About this 1.01ct natural radiant diamond

This 1.01ct natural radiant sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2245009587. Listed at 23 retailers as of October 28, 2026, with prices from €1,329 to €3,859, a €2,530 spread on the same certified stone. Queensmith lists it at €3,859. 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.
