Unakite Pendant Necklace. According to Geology.com, Unakite is named after the Unaka mountain range of Western North Carolina and Eastern Tennessee, where it was first discovered and described. The marbled greens and pink of this Unakite pendant are surrounded by silver on a magnetic bail so you can wear the necklace with, or without, the 1.75 inch round pendant. The 21 inch long necklace is made with coin shaped, translucent crystals that have a prismatic effect, and tiny sterling silver beads.
