Obscura - Obsidian Nugget BraceletLikened from the phrase "camera obscura", this bracelet also features a dimension of darkness with a single inclusion of light that projects great beauty, in this case, on anyone who wears it. It features brilliant silver plated nuggets nestled among polished Obsidian tumbled stones. All of these components are then strung on our Embraceling memory wire which has a measured diameter of 2. 25" and accommodates most wrists from 6. 5 7. 5 inches.
