About this 1.52ct natural radiant diamond

This 1.52ct natural radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6435913291. Listed at 23 retailers as of November 5, 2026, with prices from £3,012 to £6,787, a £3,775 spread on the same certified stone. NZ Jewellers lists it at £6,787. 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.
