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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3425030573. Listed at 5 retailers as of November 2, 2026, with prices from HK$8,895 to HK$19,509, a HK$10,613 spread on the same certified stone. MOH London lists it at HK$19,509. 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.
