Sterling Silver Iolite Pendant

Sterling silver multi-stone Iolite pendant is unmarked as far as I can see and tests as sterling silver.  It measures just under 2 inches, including the bail, by a little over 1 inch wide and it weighs 10.6 grams.  The bail has a slight crinkle in it in the front as can be seen in the photos.  The flaw looks much worse in the photos and is barely visible in person.
