Effy Jewelry on Instagram: "A stone this rare deserves extra-special care. Skip ultrasonic cleaners and steam, which can cause tanzanite to fracture. Instead, use a soft brush, gentle jewelry cleaner and a microfiber cloth — all included in Effy's jewelry cleaning kit — to keep its violet-blue hue glowing into the new year and beyond.
