About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552178766. Listed at 11 retailers as of November 4, 2026, with prices from HK$14,123 to HK$32,558, a HK$18,435 spread on the same certified stone. MOH London lists it at HK$32,558. 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.
