Spinning Ring

My friend and I have made the design of this to target high price customers as it will be expensive. Basically, we are making this ring for those who have a fidgeting problem and they like to do some kind of stuff when they are in tension. We are targeting mostly rich women as they are more interested in gold as compare to men. This ring has two parts. The outer side is made of gold, and it is purely made with 24 k gold, but the inner layer is based on white gold drum diamond on it. There are total 23 drums and each thick line of that drum contains a small diamond. To improve the efficiency, quality and durability of the ring, we will be adding 0.23% copper, so that we can stay in a very solid form and does not break easily. The complete drum can revolve on the ring. The cost of the ring will be as per the cost of diamond and gold. If there are more than 23 drums and each drum contains 1 or more than 1 diamond then it can be more expensive. It's like fidget spinner, but as people can’t take it everywhere this ring can be a good source for them
