Optima Ltd is developing the labradorite quarry located at Kamyany Brid vlg, Zhitomir region of Ukraine. Our products are blocks of labradorite Optima Black and Optima Bronze. Distinctive feature of the Optima Black and Optima Bronze is its fine-grained structure that is unusual for most known labradorites. This factor along with dark or bronze background makes our labradorite very applicable for many applications. A background of the Optima Black is dark with the crystals that sparkle blue and silver colors. A background of the Optima Bronze is more brownish with the crystals that sparkle bronze color and rarely blue color. A typical crystals's grain size is about 1-3 cm. Optima Black Optima Bronze Due to negligible level of iron in minerals the Optima Black and Optima Bronze labradorite never becomes rusty even in humid enviroment and its ornamentality remains permanently constant. Also, Volga Star has got low level of silica that makes this stone easy to polish and cut. We recommend to use the Optima Black and Optima Bronze as natural material for interior and exterior applications such as countertops, tiles, vanity tops, windowsills, stairs, tombstones etc. The Optima Black and Optima Bronze stone surface can be polished to a shine very easy. A resine is recommended in order to make surface "wet" but it is not needed for strengthening of tile or slab as our material is very stiff. We offer to you our main product - the blocks of Optima Black and Optima Bronze . We also may supply different products such as slabs, countertops, tiles, borders, pavings, cubes, tombstones etc. altoptima@yandex.ru http://altoptima.wixsite.com/optima-eng +38 098 469-5047 Skype: dimir2007
