The "penannular" (in the form of a ring but with a small part of the circumference missing) brooch became popular in the Celtic world at least as far back as 600 AD. Made from bronze, iron, silver, and gold, penannular brooches remained popular all the way through the Viking era.
Our Wrought Iron Penannular Brooch is simple, affordable, and historically accurate. Because they are hand-forged, each one is unique. Very cool! The 3" diameter makes it a very versatile size. An excellent choice for fastening your great kilt, ancient kilt, earasaid, or fly plaid.
Be aware wrought iron will rust if not properly cared for. Your brooch will arrive packed in protective coating of oil. This keeps them from rusting in storage and transit. Just wipe it clean with a paper towel before first use. Keep it dry and you'll be good to go. You may want to coat it once in a while with a good rust-inhibiting oil (such as products typically used to clean and protect guns).
