The intricate Rhodium plated brooch is made with Connemara Marble detail. This stone has a wide range of green color tones and designs making each piece of jewelry unique and different. The Tara Brooch is named after the Hill of Tara and dates back to 700 AD. All of Solvar's Connemara Marble is authentic and directly from the Joyce family mine in Connemara, Ireland. Connemara Marble is also only found in Ireland and dates back over 900 million years. This brooch would look beautiful on a coat or Celtic wrap.
