About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded J 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 1458362282. Listed at 20 retailers as of October 29, 2026, with prices from HK$17,465 to HK$38,124, a HK$20,659 spread on the same certified stone. MOH London lists it at HK$38,124. 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.
