About this 0.81ct natural cushion diamond

This 0.81ct 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 2151576608. Listed at 8 retailers as of October 30, 2026, with prices from HK$15,330 to HK$20,320, a HK$4,990 spread on the same certified stone. Jared lists it at HK$20,320. 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.
