Silversmith,
Anderson Koinva
has provided us with some hand-made, sterling silver neck rings as shown below. The silver is flexible enough to “mold” around the neck and sturdy enough to handle the weight of most pendants. End to end it measures approximately 14 inches with the back open (there is no clasp) and about 1/8 of an inch wide. A very dramatic way to display any pendant as a choker!
NOTE: This pendant is no longer available for sale.
