Bluestone is a manmade stone. It's a combination of natural minerals - cobalt, silica, and borax. The cobalt is what gives these earrings their blue tone. Even though it's manmade, Bluestone still carries beneficial energetic properties. It helps to boost your intuition and open up your Third Eye to receive guidance via your inner vision.
The setting is .925 sterling silver.
