This is a beautiful pair of handmade Native American Indian Turquoise earrings.  They are made out of sterling silver.  The silver has dark patina from age.  The butterfly backings I think are possibly made of steel.  The earrings measures a bit over 3/8" tall.  They weigh without the backings a total of 2.4 grams.  Please see photos above for condition.  The earrings look beautiful when worn.  Thank you for looking!
