About this 1.51ct natural cushion diamond

This 1.51ct 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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2225482847. Listed at 22 retailers as of November 1, 2026, with prices from HK$41,977 to HK$78,172, a HK$36,195 spread on the same certified stone. MOH London lists it at HK$78,172. 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.
