almas

Almas is the Arabic word for diamond, descended from Greek adamas — unconquerable, invincible — which the Greeks applied first to a legendary indestructible alloy and later to the hardest known mineral. Greek adamas, from a- (not) plus damazein (to tame or subdue), passed into Arabic through Syriac intermediaries during the early Islamic centuries, acquiring the definite article al- and settling into Arabic as almās, the standard term for diamond. From Arabic the word spread into Persian, where almas still means diamond, and into Turkish, where the form is elmas.

The same Greek adamas traveled a parallel route westward through Latin adamantem, producing English adamant, French diamant, Spanish diamante, Italian diamante, and English diamond. The two branches — diamond through Latin and almas through Arabic — diverged from the same Greek root and carried different portions of its original meaning. The Latin branch kept the sense of absolute hardness, hardening into an adjective for unyielding conviction. The Arabic branch kept the mineral.

Greek mineralogists identified unconquerability as the diamond's essential property, and medieval lapidaries built entire therapeutic systems around it. A diamond in the inventory of a 14th-century Arab physician served simultaneously as a precious stone, a pharmaceutical ingredient, and a talisman against poison. The Persian poet Hafez, writing in 14th-century Shiraz, used almas in ghazals as a standard metaphor for clarity and brilliance — the hardest and most transparent substance, contrasted with the softness of what gives way.

Almas is today the name of a premium Russian beluga caviar brand, packed in 24-karat gold tins and marketed as the world's most expensive caviar. The naming was deliberate: almas (diamond in Arabic and Persian) for a product priced beyond other luxuries. The ancient Arabic mineralogical term, descended from a Greek metaphor for indestructibility, is now also a branding decision on a tin of fish eggs.
