Glyptic ("Engraved object" in ancient Greek)
Practiced since antiquities, glyptic is the art of engraving, intaglio (intaglio) or in relief (cameo), on fine stone.
Jet
Since ancient times, jet was known and exploited in England: balls, pendants and amulets are found in ancient burial mounds. The Romans exported English jet to Rome, where it was worked into jewelry. In the 18th century, “jet pastenotriers” made mourning jewelry, rosaries, crosses, and French craftsmanship was very active. In the late 19th and early 20th centuries, several tons of jet were produced annually. Very popular during the Victorian era, it became its symbol.
