This rare and wonderful perpetual calendar charm is fashioned in 15k yellow gold and sterling silver. A perfect example of the Victorian proclivity for ornament - even when it comes to the most functional of objects - this elaborate pendant is designed to be a keeper of time, in perpetuity. One side is studded with two tiny faceted garnets and indicates the calendar month and day, the number of hours of daylight, and the time of the sunrise and sunset. The reverse is set with a turquoise cabochon and engraved with the days of the week, along with their planetary symbols (Sunday, Sun; Monday, Moon; Tuesday, Mars; Wednesday, Mercury; Thursday, Jupiter; Friday, both Venus and Earth; Saturday, Saturn). The silver medallion at the center is engraved with the pertinent days, dates, months, and hours. Each gold disc rotates independently for ultra precise calendar-keeping. Hangs from a new 18" 14k yellow gold chain.
