How to recognize it
Trigonite can be identified by its dark brown to black color and submetallic luster. It has a hardness of 3.5 to 4 on the Mohs scale, which is relatively soft, and a moderate density. The mineral does not have a distinct streak. Due to its rarity and lack of distinguishing features, it is often difficult to differentiate from other dark, lead-bearing arsenates without chemical analysis.
Indicative prices
Trigonite is not commonly traded as a gemstone or jewelry material, and its market presence is limited. As a collector's specimen, trigonite can vary in price depending on origin, rarity, and aesthetic appeal. Indicative prices for well-formed specimens may range from EUR 50 to EUR 200 or more, but this varies by source and quality.
