Set in 18K gold, this diminutive "Gemme Nummarie" pendant is mounted with an ancient Roman coin . The pendant is designed with a bronze coin dating from the first half of the 4th century AD set within a smooth 18k bezel, the front depicting a draped right-facing bust of Constantine I with a rosette diadem, verso with two soldiers bearing standards, dedicated to the glory of the army. This crisply preserved ancient coin within its streamlined modern setting is diminutive but compelling Bulgari "gem coin".
