This necklace has five irregularly-shaped agate drops, some of which have the "iridescence" seen in fire agates (though the pics do not show it very well). The sterling caps on the agates have intricately engraved floral designs on them, and the sterling chain is 18 inches long, with a jump-ring clasp. As a comparison, the longest agate in the middle measures 1-7/8 x 3/8 inches. I will lightly polish the sterling before shipping Really a lovely agate necklace!
