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 SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551490082. Listed at 14 retailers as of October 28, 2026, with prices from HK$31,533 to HK$71,641, a HK$40,108 spread on the same certified stone. Queensmith lists it at HK$71,641. 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.
