About this 1.57ct natural radiant diamond

This 1.57ct 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 5563167964. Listed at 8 retailers as of November 3, 2026, with prices from £6,550 to £10,548, a £3,999 spread on the same certified stone. NZ Jewellers lists it at £10,548. 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.
