About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded H 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 2377518025. Listed at 22 retailers as of November 1, 2026, with prices from HK$58,681 to HK$103,432, a HK$44,751 spread on the same certified stone. MOH London lists it at HK$103,432. 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.
