About this 0.91ct natural radiant diamond

This 0.91ct natural radiant sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6203543404. Listed at 11 retailers as of October 31, 2026, with prices from €2,144 to €3,207, a €1,063 spread on the same certified stone. The Diamond Guys lists it at €3,207. 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.
