About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded D 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 6541734496. Listed at 17 retailers as of November 1, 2026, with prices from HK$24,303 to HK$53,736, a HK$29,433 spread on the same certified stone. MOH London lists it at HK$53,736. 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.
