Byzantine Empire, circa 600s.
Although it seems like a contemporary piece, this is actually an ancient high karat (approximately 23 Kt) gold and amethyst earring, circa 7th century CE. We converted it to a pendant by adding the bail.
Metal x-ray analysis reports: gold – 95.47 %, silver – 2.79%, copper – 1.78%.
The amethyst bead measures 12 x 10 mm (7/16 x 6/16 in.)
Total length with the bail is 50 mm (2 in.)
