We use a combination of natural diamonds, precious gemstones and solid gold - they are durable and can be worn all day and in the shower, unless they contain a small Opal. Opals are a porous stone that can absorb water and become temporarily transparent until they are fully dry. Please be careful when doing physical activity to avoid any scratches to the piece or damage to the stones. Once or twice a month, place your ring in warm water with very little non-detergent eco soap and let soak for a 2-3 minutes. Gently brush with a baby tooth brush around and underneath the stone setting. Rinse in warm water and dab dry with a soft cloth. This will keep it always looking new.
