About this 1.53ct natural cushion diamond

This 1.53ct 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 3425242560. Listed at 21 retailers as of October 31, 2026, with prices from HK$27,529 to HK$56,997, a HK$29,468 spread on the same certified stone. MOH London lists it at HK$56,997. 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.
