About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2185980971. Listed at 26 retailers as of October 31, 2026, with prices from HK$41,174 to HK$80,988, a HK$39,813 spread on the same certified stone. MOH London lists it at HK$80,988. 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.
