Drawing Bracelet

Shape Bracelet

I had this idea to design a bracelet with form and colour. But first the has to be a drawing to bring my idea to life. That is when i draw a bracelet with two shapes, circle and square. But i do not know what material to use. I was thinking of making square shape with brass and circle with silver, to have a colour contrast. A bracelet has to have a pendant, My design pendant  is a square shape, inside the will be a circle.
