The chemical composition which was given by Tschermak in 1884 for this dravite approximately corresponds to the formula NaMg 3 (Al,Mg) 6 B 3 Si 6 O 27 (OH), which is in good agreement (except for the OH content) with the endmember formula of dravite as known today. Dravite varieties include the deep green chromium dravite and the vanadium dravite.

Opal is a mineraloid, with the next chemical formula SiO 2 *nH 2 O. We can see from the formula that opal has water in its composition. Opal contains up to 20% water trapped in its silica structure. When it is subjected to heat or constantly exposed to the sunlight, opal can dry out, leading to tiny fracture formation.Localities for Andean Opal Hide.
