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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1403844535. Listed at 19 retailers as of October 29, 2026, with prices from HK$11,055 to HK$23,197, a HK$12,142 spread on the same certified stone. MOH London lists it at HK$23,197. 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.
