About this 1.3ct natural cushion diamond

This 1.3ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded J 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 6505604016. Listed at 15 retailers as of October 31, 2026, with prices from HK$19,988 to HK$43,563, a HK$23,574 spread on the same certified stone. MOH London lists it at HK$43,563. 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.
