About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6312770209. Listed at 19 retailers as of November 4, 2026, with prices from HK$11,012 to HK$23,988, a HK$12,976 spread on the same certified stone. MOH London lists it at HK$23,988. 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.
