Dolomite, otherwise known as dolostone, comprises mineral dolomite formed through the post-depositional alteration of limestone and mud within magnesium-rich groundwater. The use of dolomite for countertops is becoming more widespread as people become aware of its visual aesthetic paired with great usability.Spectacular specimen measuring 7.5 x 5.9 cm, with groups of twinned rhombohedral dolomite crystals, with very well defined faces and edges.Many people are not able to get all of the vitamins and minerals that their bodies need from diet alone. A multivitamin can be a way to supplement your diet to ensure your body has what it needs to function at its optimum.
