16mm Australian white pearl is a very precious and rare pearl, which belongs to the white butterfly shell and is one of the largest pearl shells in the world. Compared with other types of pearls, the diameter of Australian white pearls is larger, generally above 10mm, and the top grade can reach 20 mm. Although the diameter is larger, it will not give people a heavy feeling because of the thick pearl layer and extraordinary texture. The white body color of Australian white pearls is often silver, which makes them more unique and beautiful.
