Crystals need to be looked after properly. Please make sure your crystal is cleansed and charged regularly. To do this, leave your crystal directly in the sun, to absorb sun energy whenever you can.
Although all our chains are sterling silver, gold-filled and gold plated; some of our pendants are set in sterling silver and some pendants are metal (silver plated/ gold plated copper). The silver and gold plating on our pendants will wear easily, if worn in the water - particularly the ocean.
Saltwater also tarnishes sterling silver, leaving behind black/dark marks.
For our pendants that are set in sterling silver, it will say so in the product description.
To prolong the life of your jewellery, please take care of both the crystal and the metal.
