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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2151581034. Listed at 10 retailers as of November 1, 2026, with prices from HK$11,950 to HK$20,412, a HK$8,462 spread on the same certified stone. 77 Diamonds lists it at HK$20,412. 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.
