Jumbo Grey 17 mm

​🏛️ BEYOND EXTRAORDINARY: The 17.1mm "Monster" Round

​In the pearl trade, nature occasionally redefines the scale. This isn't just a larger gem; it’s a 1-in-10,000 biological miracle.

To reach 17.1mm, this oyster survived a Third Graft cycle—a feat with a success rate of under 10%. Maintaining mirror-like luster and a 90% clean surface over this massive surface area is nearly impossible.
