Adamant

Since diamond is now used exclusively for the hardest gem, adamant has mostly poetic or figurative use. As an increasingly archaic word, it - and its adjectival form adamantine - is especially often seen in fantasy fiction. For instance, in Tolkien's Lord of the Rings, Galadriel's ring Nenya is also named the "Ring of Adamant".

Adam Adamant Lives was a BBC television series in the 1960s.

The Adamant Music School[?] is a piano school located in the village of Adamant, Vermont[?] just north of Montpelier. The Adamant Press[?] is also located in the village.

The Adamant was an iron barque (sailing ship) that brought immigrants to New Zealand in the late 19th century.
