Custom designed 8mm black lava stone beads with dark blue lace agate beads that encircle the necklace. Perfect for men, women and children. Lightweight and perfect for any occasion. The necklace is closed off with a silver lobster clasp. These come in a standard size of 18". I can also make them in 14", 16", and 20". Just let me know what size you need when you purchase it and I'll make it for you. I do make custom necklaces as well - so if you have an idea of something you'd like and can't find it - let me know and I might be able to make it for you. Thank you for looking
