About this 1.01ct natural radiant diamond

This 1.01ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1439359863. Listed at 15 retailers as of November 5, 2026, with prices from $4,109 to $10,966, a $6,857 spread on the same certified stone. NZ Jewellers lists it at $10,966. 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.
