About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551393833. Listed at 22 retailers as of November 6, 2026, with prices from HK$33,301 to HK$70,978, a HK$37,677 spread on the same certified stone. MOH London lists it at HK$70,978. 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.
