Flowering Tube Onyx is a rare, decorative mineral material known for its autumn-colored banding, circular orbs, and intricate flower-like patterns formed within tube structures.
Key Characteristics
• True Composition: Despite the trade name "onyx" (which typically refers to silicon dioxide quartz), flowering tube onyx is actually a calcite-based stalactitic or cave-formation material.
• Origin: Primarily discovered and mined in Juab County, Utah (such as near Nephi) in the 1960s.
