Snowflake Obsidian is a natural volcanic glass containing the mineral Cristobalite in the form of white "snowflake" crystal patterns. Snowflake Obsidian is calming and soothing. It teaches you to value mistakes as well as successes. A stone of purity, Snowflake Obsidian provides balance for body, mind and spirit. It helps you recognize and release “wrong thinking” and stressful mental patterns. Snowflake Obsidian is also a birthstone for those born in the sign of Virgo. This stunning bracelet is set with highly polished stones that I think display the best range of Snowflake Obsidian--everything from "light snow" to "blizzard". Small faceted black onyx are the perfect complement to the larger stones, and provide a slight reflective quality that really makes this bracelet a must-have. The setting is solid sterling silver--feels substantial on your wrist, but not heavy at all. The bracelet width is 1" and length is 81/4" with adjustable toggle closure.
