About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded H 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 6545348944. Listed at 14 retailers as of October 29, 2026, with prices from HK$23,852 to HK$52,819, a HK$28,967 spread on the same certified stone. MOH London lists it at HK$52,819. 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.
