About this 0.9ct natural round diamond

This 0.9ct natural round sits in the just-under-one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 2546912656. Listed at 23 retailers as of October 30, 2026, with prices from £533 to £2,225, a £1,692 spread on the same certified stone. NZ Jewellers lists it at £2,225. 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.
