Hardstone carvingHardstone carving, in art history and archaeology, is the artistic carving of semi-precious stones (and sometimes gemstones), such as jade, rock crystal (clear quartz), agate, onyx, jasper, serpentinite, or carnelian, and for objects made in this way. Normally the objects are small, and the category overlaps with both jewellery and sculpture. Hardstone carving is sometimes referred to by the Italian term pietre dure; however, pietra dura (with an "a") is the common term used for stone inlay work, which causes some confusion.
SardisSardis (ˈsɑrdɪs ) or Sardes (ˈsɑrdiːs ; Lydian: 𐤳𐤱𐤠𐤭𐤣, romanized: ; Sárdeis; Sparda) was an ancient city best known as the capital of the Lydian Empire. After the fall of the Lydian Empire, it became the capital of the Persian satrapy of Lydia and later a major center of Hellenistic and Byzantine culture. Now an active archaeological site, it is located in modern day Turkey, in Manisa Province near the town of Sart. Sardis was occupied for at least 3500 years.
AgateAgate (ˈæɡɪt) is the banded variety of chalcedony, which comes in a wide variety of colors. Agates are primarily formed within volcanic and metamorphic rocks. The ornamental use of agate was common in Ancient Greece, in assorted jewelry and in the seal stones of Greek warriors, while bead necklaces with pierced and polished agate date back to the 3rd millennium BCE in the Indus Valley civilisation.
