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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1499444874. Listed at 2 retailers as of October 29, 2026, with prices from HK$8,996 to HK$13,412, a HK$4,416 spread on the same certified stone. MOH London lists it at HK$13,412. 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.
