Key Features Celtic knot design Colour - pale green Pendant - approx. 3 cm x 1.6 cm 18\" Sterling silver link chain Lobster clasp fastening Presented in a beautiful gift box This stunning  pendant necklace features an iconic Celtic knot design with a lime green Highland Marble on its base. Scottish Marble has been prized by fishermen for centuries. On the Isle of Iona they would not leave port without their lucky green gems. It has been used by healers to help the body return to a time unhindered by the stresses and pollution of modern times. Highland Marble is mined by hand by Two Skies in the Scottish Highlands and the West coast islands. Over 800 million years ago, limestone was formed under the oceans of Scotland. As plant life of the time died and settled on the sea bed the life-sustaining chlorophyll from these plants, coupled with the metamorphosis of the limestone, resulted in what we now know as Scottish Marble. To own a piece of Scottish marble is to own a piece of Scotland itself!
