About this 1.5ct natural cushion diamond

This 1.5ct 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 2387861420. Listed at 18 retailers as of November 4, 2026, with prices from HK$21,467 to HK$48,683, a HK$27,216 spread on the same certified stone. MOH London lists it at HK$48,683. 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.
