About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6247005011. Listed at 16 retailers as of November 4, 2026, with prices from HK$16,051 to HK$37,953, a HK$21,902 spread on the same certified stone. MOH London lists it at HK$37,953. 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.
