An engagement ring is a piece of jewelry traditionally given during a marriage proposal. It symbolizes a promise of commitment and love between two people. Typically, these rings feature a prominent gemstone, often a diamond, set in precious metal like gold or platinum. The design can vary widely, reflecting personal tastes and styles. In many cultures, the engagement ring is worn on the fourth finger of the left hand, known as the ring finger. This practice is based on the belief that a vein in this finger, called the vena amoris, runs directly to the heart, symbolizing love and connection.
