About this 0.78ct natural cushion diamond

This 0.78ct 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 7562282648. Listed at 7 retailers as of November 6, 2026, with prices from HK$5,737 to HK$8,222, a HK$2,485 spread on the same certified stone. Steven Stone lists it at HK$8,222. 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.
