Listing is for one necklace Chose from the following stones: obsidian (black) / rose quartz (pink) / clear quartz (transparent)/ amethyst (light purple) Made to order Each is unique and no two are the same Completely adjustable chain – not sure if you may have an allergy to the chain? Feel free to contact me for more options. The image shows obsidian: Obsidian helps to protect very sensitive souls. It is the stone of the soft hearted and gentle. You can use obsidian to help block negativity of any kind and it symbolises self control and resilience. Black stones/crystals in general have protective energies as black is the absence of light, and therefore can be used to create invisibility. The crushed tourmaline surrounding the crystal has been coated with a hypo-allergenic solution. Please be aware that due to the tourmaline being crushed, it may feel a tiny bit rough on skin. There may be traces of clear quartz particles as often they grow with the tourmaline. Keep away from water and chemicals to reduce wear and damage to the chain and natural stones. – It will come delicately gift packaged complete with a recycled Bambi Jewellery card.
