About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded E 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 6552041471. Listed at 13 retailers as of November 4, 2026, with prices from HK$6,230 to HK$15,425, a HK$9,195 spread on the same certified stone. Flawless Fine Jewelry lists it at HK$15,425. 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.
