This sterling silver round Trinity ring is made from Connemara marble, a unique stone that dates back over 900 million years and is known as “Ireland’s gemstone”. Our Connemara marble is authentic, coming from the Joyce family mine in Connemara, County Galway. This eye-catching ring features the meaningful Trinity Knot that symbolises eternal life and endless love, and is surrounded by Celtic knot-work. This marble Trinity Knot ring has been hallmarked in Dublin Castle. Due to the unique patterns and colours of the marble, each ring may vary from the ones in our images.
