PEARL.—References in OT are uncertain. In Job_28:10gâbîsh is in AV [Note: Authorized Version.] tr. [Note: translate or translation.] ‘pearls,’ but in RV [Note: Revised Version.] ‘crystal,’ while pĕînîm in same verse is in AV [Note: Authorized Version.] tr. [Note: translate or translation.] ‘rubies,’ hut in RVm [Note: Revised Version margin.] ‘pearls.’ In Est_1:6dar should perhaps he rendered ‘pearl’ or ‘mother-of-pearl.’ In NT pearls (Gr. margaritai) are mentioned in Mat_7:8; Mat_13:45 f., 1Ti_2:9, Rev_21:21. The last ref. must be to mother-of-pearl. Pearls are a pathological production of the mollusc Avicula. margaritifera.
