Master Series Triple Locking Stacker Ring
A full pound of stainless steel locked by a pin through three graduated rings makes this adornment a sight to behold. At an inch and a half wide with a dangling lock atop, this ring is certainly not intended for discretion.
While the rings are graduated in size (1.75, 1.875, and 2.0), the effective diameter is limited to the smallest rimg at 1.75. I suppose the individual rings could be worn, bit you have finer pieces in your collection for that purpose.
