About this 0.8ct natural round diamond

This 0.8ct 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 1439297965. Listed at 14 retailers as of October 27, 2026, with prices from £654 to £2,319, a £1,665 spread on the same certified stone. NZ Jewellers lists it at £2,319. 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.
