About this 0.81ct natural cushion diamond

This 0.81ct natural cushion 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 2556109769. Listed at 10 retailers as of November 6, 2026, with prices from HK$4,663 to HK$11,496, a HK$6,833 spread on the same certified stone. MOH London lists it at HK$11,496. 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.
