About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded G 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 1528811405. Listed at 12 retailers as of November 2, 2026, with prices from HK$8,605 to HK$20,265, a HK$11,660 spread on the same certified stone. MOH London lists it at HK$20,265. 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.
