Nickel

The modern gift symbol for the 21st wedding anniversary is nickel. This metal is a symbol of strength and endurance, which is why it can be used to represent the couple’s relationship. In addition, this metal has the ability to withstand corrosion, making it an excellent choice for a gift.

Nickel is also a popular choice because it’s available in many forms, including a wide variety of artwork and other forms of decoration. You can find anything from jewellery to sculptures made out of nickel all over the internet or at local stores.

Gifts for this anniversary could include anything from a decorative sculpture to a beautiful bracelet or necklace that features this metal prominently in its design.
