About this 1.51ct natural cushion diamond

This 1.51ct 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 6542741720. Listed at 17 retailers as of November 4, 2026, with prices from HK$37,886 to HK$74,233, a HK$36,347 spread on the same certified stone. MOH London lists it at HK$74,233. 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.
