Optical Calcite, also known as Iceland Spar, is a crystal of clarity—both in its physical form and energetic properties. It’s naturally double refractive, which means when you look through it, images appear doubled. This quality encourages you to look deeper, shift your perspective, and see what’s really there. Energetically, Optical Calcite is used to clear mental fog, support clear thinking, and bring focus during times of overwhelm or when your energy feels pulled in too many directions. It's often worked with during journaling, planning, or meditation—any practice that benefits from greater insight and direction. This piece is beautifully transparent, with rainbows that shimmer in the light. A powerful crystal to keep close when you’re seeking truth, focus, or energetic clarity.
