Spanning two centuries, between the 16th and 18th, gold and enamel rings of this nature are said to be of Italian or Eastern European nature. This fine specimen is housed at the Metropolitan Museum of Art in New York. Customary of the day, Jewish grooms would place the ring on their betrothed until the marriage ceremony, at which time, the ring would be kept with either the family as an heirloom or the Temple community for safe-keeping.
The gable roof portion of the ring opens to reveal an inscription. Translated, it says, "Good Luck."
As this is a museum piece, there is no price; it's not for sale. It is unknown if the ring is on loan or owned by the Met. Don't you just love this?!
