Large Monogram pendant, SE/ES or SF/FS, 14K

Stunning large Monogram pendant converted from a brooch. It has the most beautiful font spelling either ES/ES or maybe it's an F as in FS/SF. The S is high-shine rose gold and the E or F is a textured finish of buttery yellow gold. I am quite confident that this is a one-of-a-kind piece, and that we’ll never see another.
