Overview
Ruby muscovite block mica from the Giridih–Koderma belt — the deposit that gives India its near-monopoly in high-grade natural muscovite. Blocks are graded on the V-1 to V-10 visual quality ladder and split into condenser films, gauge glasses and specialty electronic parts. Ruby No. 5 commands the premium of the US$ 5–80/kg block price band; USA and Vietnam lead current demand.
Supplied by Wedge Industries Limited with manufacturing and processing bases in India, UK, Spain and China, exporting to 45+ countries.
