About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1236761950. Listed at 8 retailers as of October 27, 2026, with prices from $2,226 to $4,784, a $2,558 spread on the same certified stone. NZ Jewellers lists it at $4,784. 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.
