This is a great Southwestern Mexican Sterling Pendant that is a design by I. De la Serna. It has a mark on the Back that looks like this Silversmith's Trademark and is marked Sterling on the heavy loop. It has a Silver chain that is not marked. The Turquoise Stones are very close in color having a very close aqua shade.This is a rather large round ( over 2” in diameter ) pendant. It has a Big Round Stone that measures 3/4" in length and is 3/8" and has (4) tear drop shaped Turquoise Stones around the Pendent with (4) more smaller tear drop stones around the Pendent and alternate with the other ones in placement. It is a very attractive and beautiful piece of Jewelry and would be a very attractive accessory to wear.
