Root Explanation

Demantoid is formed from 'dema' (from the Greek 'demas', meaning 'body') and 'toid' (from the Greek 'eidos', meaning 'form' or 'shape'). The word refers to a gemstone that resembles a diamond in form and appearance, hence the connection to body and shape.

Memory Tip

Think of 'body' ('dema') and 'form' ('toid') to remember that 'demantoid' refers to a gemstone that has the form of a diamond.
