I really like this ring from  Mabel Hassell, a very innovative way of using stones for a ring, reminds me of a mountain range viewed from above. 

"Inspired by the colours and cuts of gemstones, my current work focuses on highlighting gems by presenting them in a different perspective and in a non-precious manner. This approach allows me to create unorthodox pieces that emphasise the vibrant gemstones even more so than just setting them traditionally."
