Sphalerite is a vibrant, high-vibration crystal made primarily of zinc sulfide. It’s often found with striking metallic luster and colors ranging from deep reds and browns to yellow, orange, and black—sometimes even sparkling with tiny crystal faces. Its name comes from the Greek word sphaleros, meaning “deceptive,” because its appearance can mimic other minerals. While it’s primarily known as a major source of zinc in the industrial world.
