About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded I 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 2377724079. Listed at 23 retailers as of November 2, 2026, with prices from HK$52,040 to HK$97,733, a HK$45,693 spread on the same certified stone. MOH London lists it at HK$97,733. 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.
