About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7496080636. Listed at 12 retailers as of November 4, 2026, with prices from HK$4,945 to HK$12,372, a HK$7,427 spread on the same certified stone. MOH London lists it at HK$12,372. 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.
