This is a fun Sea Turtle pendant of Chinese Fluorite (with great color and purple stripes!). The back of the pendant is stamped 925 to show that it is sterling silver (it will tarnish, but just use a dab of silver/jewelry polish and it will gleam again!).
I have shown a picture of the bail, which is on one of the front flipper/feet of the turtle - this lets the pendant hang at an angle, making it look like the sea turtle is swimming.
The pendant has an overall length of 31 mm (1.2") and is 30 mm (1.1") wide at the widest point The pendant weighs 6 grams (0.2 ounces).
