About this 0.81ct natural cushion diamond

This 0.81ct natural cushion sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1425340919. Listed at 19 retailers as of October 28, 2026, with prices from HK$5,972 to HK$13,154, a HK$7,182 spread on the same certified stone. MOH London lists it at HK$13,154. 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.
