About this 0.8ct natural cushion diamond

This 0.8ct natural cushion sits in the just-under-one-carat band, graded F 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 5231993659. Listed at 14 retailers as of November 1, 2026, with prices from HK$6,227 to HK$14,568, a HK$8,342 spread on the same certified stone. MOH London lists it at HK$14,568. 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.
