Beautiful crystal necklace with silver accents on a 20” adjustable black cord! The crystals include amethyst, agate, tigers eye, lapis lazuli, and goldstone. They can hold essential oils, an anointing oil, or anything else you can fit in there! They do come with a pipette. Please note that the screw is where it attaches to the necklace - while it is not likely for it to fall off while you wear it, I would suggest occasionally tightening it! I haven’t had any issues, but better safe than sorry!
