About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded H 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 6495045073. Listed at 9 retailers as of November 1, 2026, with prices from HK$4,504 to HK$11,280, a HK$6,776 spread on the same certified stone. MOH London lists it at HK$11,280. 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.
