About this 5.18ct natural emerald diamond

This 5.18ct natural emerald sits in the over five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6234356753. Listed at 7 retailers as of October 28, 2026, with prices from $115,060 to $208,832, a $93,772 spread on the same certified stone. MOH London lists it at $208,832.
