About this 0.8ct natural cushion diamond

This 0.8ct natural cushion sits in the just-under-one-carat band, graded I 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 1379667122. Listed at 21 retailers as of November 4, 2026, with prices from HK$6,474 to HK$14,084, a HK$7,611 spread on the same certified stone. MOH London lists it at HK$14,084. 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.
