About this 0.81ct natural radiant diamond

This 0.81ct natural radiant sits in the just-under-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 7433488651. Listed at 17 retailers as of November 1, 2026, with prices from £1,075 to £2,990, a £1,915 spread on the same certified stone. NZ Jewellers lists it at £2,990. 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.
