This gorgeous bracelet was made by Lumina Jewelry.

Per the artist's description:
"Dramatic nuggets of soft green and black prehnite wrapped in fine silver and finished with a Thai Hill Tribe toggle.

The bracelet is 7 1/4 inches when worn (8 inches when stretched out flat). For sizing secrets, see http://www.1000markets.com/users/luminajewelry/blog_posts/3780. All Lumina handmade jewelry is shipped in a pretty gift box.

Bracelets, unlike earrings and necklaces, are made for the wearer's enjoyment as they are in view throughout the day with no need of a mirror.

Fine silver is very bright and extremely tarnish resistant compared to sterling silver. Fine silver is 99.9% silver, Thai hill tribe silver is at least 97% silver, and sterling silver is 92.5% silver." (via 1000 Markets)
