Two adjoined cone shapes make up this finely wrought bead, likely one of many on a stunning necklace. Its lavish detail attests to the craftsmanship of artisans in the Fatimid dynasty (909–1171). Taking their name from Fatima, daughter of the Prophet Muhammad, the Fatimids consolidated power through North Africa and as far east as the Levant and Hijaz. Ruling from the capital city of Cairo, they maintained important trade relations within Africa as well as with empires around the Indian Ocean and Mediterranean Sea. The nearby Byzantine Empire (ca. 330–1453) was a particularly important trading partner. Not surprisingly, some Fatimid jewellery has very distinct links to Byzantine objects (see AKM594).
Many objects in the Aga Khan Museum Collection display the art of filigree, in which fine threads of gold wire are manipulated to form scrolling patterns (see AKM495, AKM496, AKM497). This bead demonstrates a particular style of filigree known as “rope and grain filigree,”  which combined twisted fine wire known as “rope” along with beaded granulation to create a complex and almost sculptural ornament. A handful of comparable beads exist in public and private collections today, including similar biconical beads in the Metropolitan Museum of Art, New York, the Khalili Collection, London and the Al Sabah Collection in Kuwait. 
This openwork filigree is referred to as mushhabbak (latticework) in 12th-century trousseau lists from the Cairo Geniza,  a trove of medieval documents found in the Ben Ezra Synagogue in Fustat or Old Cairo, Egypt. The Cairo Geniza provides a great deal of important information about jewellery production during the Fatimid period, indicating prices, terminology, and production details about the goldsmithing and jewellery industry, much of which was staffed by Jewish craftsmen.
The Fatimids obtained gold from a number of sources, including nearby mines in Nubia (modern day Sudan) as well as the Kingdom of Ghana. In other cases, craftsmen melted down and repurposed metal from older jewellery, a probable fate for many Fatimid pieces which no longer exist today. The infamous looting of the treasury of Fatimid caliph al-Mustansir (1036–94) around 1070 resulted in an invaluable loss of many riches from this period.
While filigree remained an important element of Fatimid jewellery, the use of granulation eventually felt to the wayside, something that scholar Marc Rosenberg has referred to as “the battle of granulation and filigree” in which the latter eventually prevailed.4 This analysis suggests that this bead is among the earliest of Fatimid jewel types.
