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 standard cut grade stated by the retailer rather than the lab and certified by GIA 15889065. Listed at 5 retailers as of October 29, 2026, with prices from €2,142 to €4,106, a €1,964 spread on the same certified stone. MOH London lists it at €4,106. 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.
