About this 0.89ct natural asscher diamond

This 0.89ct natural asscher sits in the just-under-one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7543946289. Listed at 5 retailers as of November 5, 2026, with prices from £371 to £483, a £112 spread on the same certified stone. Blue Nile lists it at £483. 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.
