About this 1.26ct natural radiant diamond

This 1.26ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded J 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 6482419850. Listed at 23 retailers as of November 5, 2026, with prices from £2,358 to £5,213, a £2,855 spread on the same certified stone. NZ Jewellers lists it at £5,213. 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.
