There is a group of rings that I haven't find a name for yet - so I still call them NoName Rings :)
Silver, square inside form of the ring creates kind of a frame for an object which is stuck between two of it's arms. Here is one of them.
Here a ball covered with black acrylic background with brass&copper elements, framed in irregular, wavy silver ring and finished with champagne crystals on the sides.
Other colour versions available on order.
