About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6542448794. Listed at 21 retailers as of November 1, 2026, with prices from HK$24,806 to HK$54,775, a HK$29,969 spread on the same certified stone. MOH London lists it at HK$54,775. 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.
