The "Awa" series is a beautifully organic series inspired by the shape of air bubbles rising in water. The fineness of the texture creates a shine which makes this series very special. The Awa ring is made up of four "awa" of different sizes, with one of them turned upside down to reveal a different texture. The ring is free-size, and the free-size feature has been carefully considered in the design. Although the ring can be adjusted, please let us know your preferred US ring size. Material: 23K Gold Vermeil (23K Gold Plated Britannia Silver 958) This piece is crafted in Britannia Silver 958, a high purity silver which retains its bright color (unlike sterling silver which tarnishes easily). We also provide a small zip lock bag in which we recommend to store your piece/s to keep them away from the air. This will help to keep them bright for a long time. We usually have this piece in stock, however as we make each piece one-by-one, occasionally we are out of stock. If you would like to know the stock status, please contact me. Alternatively, if an order is placed and we are out of stock, we will contact you. Our Britannia Silver 958 handmade production process takes approximately one week.
