About this 0.8ct natural cushion diamond

This 0.8ct natural cushion sits in the just-under-one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1225829500. Listed at 10 retailers as of October 31, 2026, with prices from HK$8,105 to HK$13,962, a HK$5,857 spread on the same certified stone. 77 Diamonds lists it at HK$13,962. 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.
