About this 1.7ct natural cushion diamond

This 1.7ct 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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2557573001. Listed at 17 retailers as of November 1, 2026, with prices from HK$39,266 to HK$77,132, a HK$37,865 spread on the same certified stone. MOH London lists it at HK$77,132. 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.
