About this 1.55ct natural cushion diamond

This 1.55ct natural cushion sits in the one-and-a-half to two carat band, graded J 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 7563411565. Listed at 6 retailers as of October 31, 2026, with prices from HK$22,075 to HK$43,864, a HK$21,789 spread on the same certified stone. MOH London lists it at HK$43,864. 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.
