About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded I 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 6541632661. Listed at 14 retailers as of November 1, 2026, with prices from HK$22,495 to HK$48,654, a HK$26,159 spread on the same certified stone. MOH London lists it at HK$48,654. 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.
