What does ec mean on a ring?

The "EC" engraving on a ring typically stands for "Eternity Collection" or "Eternity Band," indicating that the ring features a continuous line of gemstones or diamonds around its band, symbolizing everlasting love. In some contexts, it may also refer to a specific designer or collection name. If you're unsure, it's best to consult with the jeweler or retailer for precise meaning.
