This 20.28ct natural emerald sits in the over five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2231881234. Listed at 2 retailers as of October 28, 2026, with prices from HK$15,564,013 to HK$19,253,951, a HK$3,689,938 spread on the same certified stone. William & Sons Jewelers lists it at HK$19,253,951. 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.
