Oh how I love a good pair of mismatched earrings! These are made with REAL shells (not castings, the shells are actually inside the metal), and REAL sea glass found on a beach in Portugal by me. Electroformed in pure copper. The earring on the left weighs just 7 grams, the one on the right weighs 10 grams. A US quarter weighs 6 grams, so these are really not heavy! About 3 1/4 inches long.
