This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2171943911. Listed at 23 retailers as of October 30, 2026, with prices from £3,657 to £7,830, a £4,173 spread on the same certified stone. NZ Jewellers lists it at £7,830. 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.
