Kunzites were discovered for the first time in San Diego, California on or about 1902. In possessing a beautiful, rosy color with the added delight of great transparency, the gemstone quickly became a very desirable gemstone despite its short history. Commonly known as the "evening stone," this precious gemstone is nocturnal and should not be exposed to sunlight for a prolonged duration of time, less it should lose its luster. Otherwise, it is a very, durable gemstone that hits a 7 on the Mohs scale. Kunzites are known to induce relaxation, which isn't surprising given the jaw-dropping shimmer of the natural gemstone.
