Malachite is a striking green gemstone prized for its rich colour and distinctive banded patterns. A copper carbonate mineral, it has been used in jewellery and ornamentation for thousands of years, symbolising transformation, protection, and healing.

With its deep, swirling shades of green, Malachite is believed to absorb negative energy and promote emotional balance. Each stone is unique, with natural patterns that make every piece of Malachite jewellery one-of-a-kind.

Whether set in silver or gold, Malachite adds a bold and earthy elegance to any collection, perfect for those drawn to its powerful presence and timeless natural beauty.
