About this 0.78ct natural cushion diamond

This 0.78ct 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 6391477230. Listed at 4 retailers as of October 28, 2026, with prices from HK$11,808 to HK$24,840, a HK$13,033 spread on the same certified stone. MOH London lists it at HK$24,840. 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.
