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 SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5232904208. Listed at 4 retailers as of November 1, 2026, with prices from HK$7,922 to HK$11,937, a HK$4,014 spread on the same certified stone. MOH London lists it at HK$11,937. 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.
