About this 1.56ct natural radiant diamond

This 1.56ct natural radiant sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2457549291. Listed at 27 retailers as of November 4, 2026, with prices from £2,279 to £5,169, a £2,889 spread on the same certified stone. NZ Jewellers lists it at £5,169. 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.
