About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552558774. Listed at 13 retailers as of October 26, 2026, with prices from €4,223 to €7,725, a €3,502 spread on the same certified stone. Wholesale Diamonds Direct lists it at €7,725. 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.
