Chrysocolla belongs to the silicate group. It contains copper and silicon. It is a hydrated copper silicate. Chrysocolla has a massive facies. Its usual colors are blue and blue-green. Its name comes from two Greek words meaning gold and glue.

SHATTUCKITE is a hydroxylated copper silicate that does not contain aluminum. Its chemical formula is Cu5(SiO2)4(OH)2).

Very close to PLANCHEITE, their crystals have such similar appearances that they are often confused. Its color varies from blue to green.

SHATTUCKITE has a hardness of 3.5/10 on the Mohs scale (PLANCHEITE 6/10 on the same scale). Its density is greater than 4 (1 for water) and its trace is blue on porcelain.
