A similar pair of bracelets, unmarked, reportedly purchased at the former local Native American jewelry store here in Enid. The owner from whom I purchased these said she and her young daughter, now grown, had worn these as mother-daughter bracelets many years ago.
The child's size cuff bracelet only has one strand of twisted wire coiled around the wider band of silver while the small adult size cuff has a pair of twisted wire coils.
Child's size measures about 3mm in diameter, has an opening of about 3/4 inch, inside diameters of 1-1/2 inches X about 1 inch.
Inside measurement (not counting the opening) is about 3-3/4 inches
Weight is 4.91 grams.
Small adult size bracelet weighs 7.53 grams, is a bit over 4mm in diameter, has an opening of about 7/8 inch, inside diameters of about 1-15/16 inches X 1-3/8 inches and an inside measurement (not counting the opening) of about 5-1/8 inches.
