A stunning carved egg-shaped from a rough ruby rock on a custom stand A "ruby rock" typically refers to a natural formation or specimen that contains ruby crystals. Ruby is a red variety of the mineral corundum, which is composed of aluminum oxide. Here are some key points about ruby rocks. Rubies are often found in association with other minerals in metamorphic rocks, such as marble and schist, or in basaltic rocks. The specific geological conditions during the formation of these rocks contribute to the development of ruby crystals. Ruby rocks, when in their natural state, can be fascinating to collectors and enthusiasts interested in minerals and gemstones. The allure of ruby lies not only in its vibrant color but also in its historical and cultural significance.
