About this 0.81ct natural cushion diamond

This 0.81ct natural cushion sits in the just-under-one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561496538. Listed at 6 retailers as of November 1, 2026, with prices from HK$5,430 to HK$8,395, a HK$2,966 spread on the same certified stone. Diamonds Direct lists it at HK$8,395. 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.
