This ring uses a set of simple pleats for its jewel. This technique, somewhat similar to Goran Konjevod’s, made me think of Art Deco style, hence the name. The ring is closed using a lock taken from Conveyor Belt Unit. Unfortunately, folded at such small size, the lock was not strong enough to withstand the stress of the ring being put on a finger, so this design remains just decoration rather than an actually wearable piece of jewelry. The lock can be replaced with a stronger one relatively easily, however.
