Care Instructions: Semi precious gemstones need to be carefully looked after to ensure they look their best. Follow these steps to care for your Avrilea jewellery. Please keep away from water and any alcohol based products such as hairspray, perfume and lotions and avoid harsh chemicals which could damage your semi precious gemstones and tarnish the metal. We recommend cleaning gently with a dry, soft, non-abrasive cloth to carefully wipe away any dirt. Please do not use any cleaning products and never use ultrasonic or steam clean as this may alter the colour and appearance of the stone. We recommend storing your jewellery in a dark and dry place.
