The richest deposits of labradorite with copious irriziruyuschego glowing Labrador were opened in Ukraine in 1835 in the town of Stone Ford (Zhytomyr region) The most advanced techniques to develop a career in the mining complex with the latest technology and equipment to produce blocks of VOLGA BLUE labradorite of the highest quality.Bright, shimmering and intense colors make VOLGA BLUE labradorite deposits Stone Ford truly one of the most beautiful stones in the world. The unique iridescence - blinking bright blue, green and purple tones, combined with a profusion of (one square meter of rock can count hundreds of "eyes" of Labrador), talk about the exclusivity of this material.
