About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter 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 2547920500. Listed at 11 retailers as of November 4, 2026, with prices from HK$4,781 to HK$10,322, a HK$5,541 spread on the same certified stone. MOH London lists it at HK$10,322. 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.
