La cyanotrichite (non confirmée), également appelée lettsomite , est un minéral hydraté composé de cuivre, d'aluminium et de sulfate, de formule chimique Cu₄Al₂[(OH)₁₂|SO₄]·2H₂O. Ce minéral se caractérise par ses agrégats cristallins aciculaires radiaux, à l'aspect velouté, constitués de fibres extrêmement fines. Il cristallise dans le système monoclinique, donnant naissance à des amas cristallins aciculaires translucides d'un bleu vif ou à des revêtements druses. Sa dureté Mohs est de 2 et sa densité varie entre 2,74 et 2,95.
