About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551518103. Listed at 14 retailers as of October 28, 2026, with prices from HK$16,671 to HK$45,339, a HK$28,667 spread on the same certified stone. Queensmith lists it at HK$45,339. 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.
