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 colourfull cube (all sides ca. 16 mm) all covered with unrepeatable DolceVita patterns is placed between a square frame with wavy sides.
Single model made - size 19-20 (59-60)
