Howlite Statement Necklace & Earrings Set

So I believe the white/marble looking stones of this necklace are Howlite. I don't know what the black stones/beads are. The necklace itself it adjustable by you choosing with loop to fasten between approximately 16-18.5" and the centerpiece is 4.5" long and 3.75" wide. The earrings are about 1 5/8" long. It's a very elaborate, fun piece. It all looks in unused condition. I inherited this from my mom's estate and this is what my research has found. thank you! Howlite is a highly emotional stone but it contributes a great deal to aiding in physical health. In terms of physical health, the bone-coloured stone can help to balance calcium levels in the body. With this stone, you can begin to strengthen your skeleton and teeth, as well as grow luscious and shiny hair. Howlite is a stone of patience and perspective, for those who feel they need to slow it down, absorb, and clear the constant stream of chatter from the mind, it's a crystal that marries you to a more mindful way of life.
