This is another rare and stunning , closed mine turquoise that you will definitely want to add to your collection. The Battle Mountain Blue Gem Mine in Nevada produced a very hard, and beautifully rich color turquoise from 1934 until its closing. The stone is a striking blue to slight blue-green shade with deep brown, irregular matrix. This is a truly impressive pendant by Navajo artist Lucy Jake. Hallmarked "LJ" and ".925" on the back. She has done an amazing job with the sterling silver bezel of twisted rope, silver drops and cut out work. THE 18" STERLING SILVER CHAIN IS INCLUDED! Pendant and bezel measures 1 & 3/8" by 3/4". The 3/8" bail has a 7mm opening. The couple of white spots near the top of the stone are reflections from the camera flash.
