1 answer
Based on the given characteristics, it is likely that the specimen being tested is Olivine. Olivine typically has a faint green streak, a hardness of 6.5, cleavage into rectangular pieces with a rough surface, does not react to hydrochloric acid, and sinks in water. The other properties provided match up with those of Olivine as well. Therefore, it is reasonable to conclude that the specimen is indeed Olivine.
