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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5211667563. Listed at 5 retailers as of November 1, 2026, with prices from £923 to £1,679, a £755 spread on the same certified stone. 77 Diamonds lists it at £1,679. 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.
