About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6167896378. Listed at 8 retailers as of November 6, 2026, with prices from HK$7,109 to HK$11,554, a HK$4,445 spread on the same certified stone. GemTrove lists it at HK$11,554. 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.
