About this 1.57ct natural cushion diamond

This 1.57ct natural cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1156743353. Listed at 17 retailers as of October 29, 2026, with prices from HK$79,469 to HK$134,584, a HK$55,115 spread on the same certified stone. MOH London lists it at HK$134,584. 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.
