About this 0.8ct natural cushion diamond

This 0.8ct natural cushion sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6435228957. Listed at 9 retailers as of October 30, 2026, with prices from HK$13,612 to HK$19,746, a HK$6,134 spread on the same certified stone. Yorxs lists it at HK$19,746. 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.
