Adaptable jewelry using toys building bricks as base for the modularity. Allows to change the jewel color without limit. Clasps are done with these bricks, and so are completely integrated in the jewel. The degree of interchangeability of pieces is high : allows to reuse bricks from one jewel to an other. When you reuse a brick covered with a beautiful diamond, it is the same as you could reuse your solitaire in a lot of jewels! This concept is as well for high fashion jewelry than for luxurious or ready-to-wear jewelry.
