Abstract Sterling Silver Bangle Bracelet

Vintage sterling silver bangle bracelet is marked Sterling and features an abstract image of a crab or a bug or a scorpion? The opening measures about 2 1/4 inches by about 2 1/2 inches wide and the inside circumference is about 6 3/4 inches.  I have a 6 inch wrist but I could not get my hand through the opening, so this bracelet is for a petite person.  The top of the bracelet with the animal has a width of about 1 1/8 inches, and the weight of the bracelet is 18 grams.  It is in great vintage condition.
