About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded G 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 2231678376. Listed at 8 retailers as of November 2, 2026, with prices from €1,778 to €3,811, a €2,033 spread on the same certified stone. NZ Jewellers lists it at €3,811. 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.
