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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1182022177. Listed at 14 retailers as of November 4, 2026, with prices from HK$6,027 to HK$13,188, a HK$7,161 spread on the same certified stone. MOH London lists it at HK$13,188. 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.
