Egyptian Rock Crystal Heart Scarab. Late Period, 664-342 B.C. Carved in the round with ribbed loop to the underside, carapace and leg detailing. Cf. Ben-Tor, D., The Scarab: A Reflection of Ancient Egypt, Tel Aviv, 1993, pp. 76-77, nos. 1-15, for examples of this type of scarab. 8.72 grams, 25 mm (1 in.). From a London and Home Counties collection, 1920-1940. Naturalistic scarabs carved in the round are characteristic of the Late Period and were crafted from various stones, including lapis lazuli, feldspar, carnelian, and rock crystal, as exemplified here. These scarabs were attached to the wrappings of a mummy, positioned over areas of the body such as the chest, neck, and hands.
