About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded G 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 2231993494. Listed at 14 retailers as of November 2, 2026, with prices from HK$13,637 to HK$31,354, a HK$17,716 spread on the same certified stone. MOH London lists it at HK$31,354. 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.
