The 7th Wedding Anniversary is celebrated with the gift of copper in the U.S.,  appropriately the goddess of Love, Aphrodite's metal. Here to the left is one of my designs; my popular 3D heart emblem signifying your union on a Zazzle coaster.  Here on the right, it's available on a shot glass, here on the bottom right, a nifty flask with a gorgeous medallion to commemorate the day, and here on the lower left, is my romantic vintage-like rendition of "Venus's" anniversary.
