About this 0.9ct natural asscher diamond

This 0.9ct natural asscher sits in the just-under-one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 653411018. Listed at 12 retailers as of October 30, 2026, with prices from £649 to £2,208, a £1,558 spread on the same certified stone. NZ Jewellers lists it at £2,208. 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.
