About this 0.5ct natural radiant diamond

This 0.5ct natural radiant sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552826035. Listed at 15 retailers as of October 29, 2026, with prices from €430 to €1,461, a €1,031 spread on the same certified stone. NZ Jewellers lists it at €1,461. 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.
