This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 660411238. Listed at 18 retailers as of October 30, 2026, with prices from £2,497 to £4,901, a £2,404 spread on the same certified stone. NZ Jewellers lists it at £4,901. 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.
