Beauty in blue, the word Kyanite comes from the Greek words “Kyanos” and “Kuanos”, which means deep blue, reflecting the ocean’s depth. The glacial radiance and watery hues of Kyanite are discovered across the globe, primarily in Switzerland, Kenya, Brazil, Russia, India, and even in the USA. The essence of the blue ocean and the sky comes in various varieties, but the most prominent and desirable ones are orange, blue, green, and black crystals.
