For the alteration I made two plans at first. One is the scratch, the other one is the chain. I chose to do the chain one in the end since it matches others’ design more.
I tried it on a piece of fabric first to see the effect. I put one ring together with three chains, it turns out to be too complex. So I changed the design into one ring with two chains on each side, decorated by some jewels around it. I use different color of chains and jewels due to the color of clothes.
