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 SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2514947193. Listed at 5 retailers as of October 31, 2026, with prices from HK$3,256 to HK$5,084, a HK$1,828 spread on the same certified stone. Ritani lists it at HK$5,084. 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.
