I have purchased 3 Roller Ball Necklaces recently. The first was a Night Thistle Queen Super Seven…I believe one of the main stones is Amethyst. The second one was a Princess with Turquoise & Black Onyx & Desert Lace. The last & most recent was a gold Smoky Quartz Nocturnal with Brass Accents. I love them all! I can’t pick my favorite! One of a kind gorgeous jewelry is my passion….if it’s yours don’t hesitate purchasing one. You won’t be disappointed!
