About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6522428214. Listed at 26 retailers as of November 4, 2026, with prices from £4,972 to £11,175, a £6,203 spread on the same certified stone. NZ Jewellers lists it at £11,175. 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.
