Pio Siotto
Italian gem engraver

Pio Siotto (Rome, 3 May 1824 - ?) was an Italian artist active as a cameo engraver (gem engraver).
He studied architecture, figure, ornate and modeling in clay at the Academy of St. Luke in Rome, and his teacher in modeling was Pietro Tenerani. He initially apprenticed with Bartolomeo Rinaldi: but soon set up his own studio. He was prolific. Pio engraved portraits or scenes, in profile and perspective, large and small, on medallions, pins, rings, bracelets bearing engraved stones from him. His onyx (soft) cameos were engraved steel tip, while his cameos on shells and semi-precious hard stones (pietre dure), were engraved with a diamond-dust lathe.
For a noble Polish noblewoman, he engraved a series of medallions representing the Kings of Poland. This collection, in shell cameos, was begun in 1860, and completed in 1870. He completed a medallion depicting the Lacoon of the Vatican Palace.
