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 IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2554503029. Listed at 5 retailers as of November 4, 2026, with prices from HK$5,256 to HK$11,478, a HK$6,222 spread on the same certified stone. Flawless Fine Jewelry lists it at HK$11,478. 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.
