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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1239277090. Listed at 5 retailers as of October 28, 2026, with prices from HK$16,470 to HK$27,270, a HK$10,801 spread on the same certified stone. 77 Diamonds lists it at HK$27,270. 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.
