About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559455724. Listed at 11 retailers as of November 2, 2026, with prices from HK$28,671 to HK$60,246, a HK$31,575 spread on the same certified stone. MOH London lists it at HK$60,246. 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.
