blue onyx is one of the most dazzling semi-natural stones in the world. with an amazing backlight effect and a bright blue color, blue onyx is one of the most luxurious natural stones that could be found on the international market. the blue color is artificial and is caused by the dyed epoxy on the back of the white onyx slabs, but the amazing color is worth the modification.
like all onyxes, this material is fairly brittle and has natural cracks. but it can argued that the irregular lines of the cracks are a major contributor to the beauty of this onyx.
