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 6432497417. Listed at 21 retailers as of October 31, 2026, with prices from HK$21,292 to HK$46,375, a HK$25,083 spread on the same certified stone. MOH London lists it at HK$46,375. 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.
