Classic bead bracelet made of herll green prehnite with 8mm beads. Length of the prehnite bracelet 19cm, threaded on rubber.
The mineral prehnite was named after Colonel Hendrik von Prehn (1733 - 1785); spellings such as phrenite, prenhite, prenith or phrenite are therefore incorrect.
Trade names for prehnite are cape chrysolite and cape emerald, earlier common names are aedelite, chiltonite, coupholite and edelite.
