Physical properties
Hardness: Ruby (Mohs 9) and Fuchsite (Mohs 2-3); Color: Deep burgundy-red to magenta inclusions in a metallic or dark green matrix; Luster: Vitreous to pearly; Crystal structure: Hexagonal/Trigonal (Ruby) and Monoclinic (Fuchsite).
Formation & geological history
Formed through regional metamorphism of aluminum-rich rocks. Most specimens of this deep color profile originate from Southern India or Russia.
Uses & applications
Used primarily for jewelry (beads, pendants), lapidary art, and metaphysical collecting.
Geological facts
This specific piece is a 'composite' or 'reconstructed' specimen where natural ruby fragments are bound together with a metallic-flecked resin (bronze-colored veins) to create a durable jewelry bead.
Field identification & locations
Identify by looking for the contrast between the hard red corundum crystals and the softer surrounding matrix. This specific bead features stabilized resin to hold the fractured ruby pieces together.
