Here's a slightly gothic piece. A 30" wrap-around necklace made of 3mm and 6mm natural black obsidian and 4mm natural silk stone built around a sterling silver replica of an antique rosary centerpiece depicting the Seven Sorrows of the Immaculate Heart. The back of the medal depicts the Sacred Heart. An extension chain adds 3" of adjustability. The matching bracelet is 6.5", but can extend to 8.25". All findings are stainless steel except for the clasps and extension chains, which are platinum-plated.
