About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two 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 1445764456. Listed at 22 retailers as of October 30, 2026, with prices from £7,597 to £14,288, a £6,690 spread on the same certified stone. NZ Jewellers lists it at £14,288. 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.
