The centerpiece to this lovely necklace is a Nipomo Marchisite. The Nipomo stone is a natural silver color with white areas throughout. This stone is topped with a freshwater pearl. This pendant hangs from a classy Omega chain. The back of the pendant has also been textured and stamped with the hallmark and maker's mark.
Pendant measures 2-1/4-inches high (not including the bail at the top) and 7/8"-inch wide.
The Omega chain measures 18-inches, plus the hanging pendant.
I have two of these stone necklaces listed here (unless one gets sold). This one is wider.
