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 6237699378. Listed at 18 retailers as of November 5, 2026, with prices from $3,736 to $7,623, a $3,887 spread on the same certified stone. NZ Jewellers lists it at $7,623. 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.
