This is a fine Victorian shell cameo. The chariot scene is well carved, with 2 horses, Neptune, and much carving all over the cameo. The shell is brown and white. The detail is excellent of the waves, horses and Neptune. In fact, the carving fills most of this large cameo. The frame is gold-plated, with a nice design. There is an early C clasp that works well, with a safety pin on a chain. The cameo measures 3" X 2 5/8". Weight is 25.1 grams. Condition is very good for age. The gold plated frame is darkening in many areas. Minor dirt in areas. With a 10X loupe I see some very minor edge dings, but no cracks, chips or other damage. I would date this fine large cameo at c1860's-80's.
