About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded E 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 6522102034. Listed at 16 retailers as of November 6, 2026, with prices from HK$3,386 to HK$8,431, a HK$5,045 spread on the same certified stone. MOH London lists it at HK$8,431. 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.
