Rare Natural Pen Shell Pearls with White Pearl Center and 18k Gold.

1.875” long,

Pen pearls are organic gems that develop within the bivalve mollusk Pinnidae, often found off the Gulf Coast of Florida. Commonly known as a Pen Shell, it was named for its shape with one broad end finishing in a pointed tip similar to a quill pen. Each uniquely formed pearl within retains a range of lustrous black and brown tones reminiscent of its host. Because most are non-nacreous, their developing structure sometimes causes crazing and cracking. These salt water pearls are a rare natural occurrence and never cultured.
