This specimen features radiating needle-like millerite crystals from the world-class 1990s find at Thompson, Northern Manitoba, a discovery that has not been replicated since. The millerite aggregates form interlocking balls of radiating crystals, with exposed cross-sections along the edges that highlight this unique growth habit. The greenish-metallic tufts of millerite, a nickel sulfide, display a rich, velvety lustre with an iridescent tarnish. These specimens have become increasingly rare on the market and are considered classic Canadian material.
