This unusual blue gemstone is angelite from Peru. This natural blue color has been described as lilac blue; I would call it periwinkle blue. If you have every seen lilacs in this shade you will recognize it immediately. The pale but well saturated blue beads are 10mm. The angelite is accented with 13mm sterling silver beads. The necklace has a sterling silver clasp and it measures 29" long. This is such a gorgeous blue. Very unusual.
