About this 1ct natural radiant diamond

This 1ct 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 7551618263. Listed at 16 retailers as of November 4, 2026, with prices from $3,165 to $8,329, a $5,164 spread on the same certified stone. NZ Jewellers lists it at $8,329. 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.
