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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6341834366. Listed at 23 retailers as of November 1, 2026, with prices from HK$46,057 to HK$86,373, a HK$40,316 spread on the same certified stone. MOH London lists it at HK$86,373. 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.
