From the Nocturne Collection. The Sirenum II is a lighter take on the Sirenum choker. With a thin curb chain, it allows the labradorite stone to take center stage and float beautifully as the focal point of this design. Labradorite is truly a Canadian stone. Discovered in Labrador the Inuits once called labradorite a "fire stone". According to Inuit legend, a warrior saw the Northern Lights trapped in the rocks and struck them with his spear to free some of the lights. This stone is known for its grounding properties. It protects and cleanses the aura while connecting us with earth energies. Due to the nature of natural stones colour may vary slightly.
