Natural Rare Beautiful Black QUARTZ Crystal Cluster.
Natural Rare Beautiful Black QUARTZ Crystal Cluster.
• The black quartz crystal is the same mineral as smokey quartz and morion quartz, and only differs from the common quartz mineral due to its aluminum content.
▪︎ Aluminum is the root cause of its light-absorbing characteristic, which causes a translucent-gray to jet-black coloration.
• Pure quartz maintains a SiO₂ chemical structure and is translucent.
• The union of aluminum to the black quartz crystal changes the chemical structure to (AlO₄)⁴⁻ and creates a molecular structure that absorbs light.
