About this 0.65ct natural radiant diamond

This 0.65ct natural radiant sits in the half to three-quarter carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 780654921. Listed at 15 retailers as of November 5, 2026, with prices from £290 to £1,203, a £913 spread on the same certified stone. NZ Jewellers lists it at £1,203. 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.
