Ammite is a term used in gems and minerals. Spelled with two M's and a silent E, the word is pronounced /ˈæm.aɪt/. The first syllable is pronounced as in "ham", the second syllable as in "might". The correct spelling of the word is important as it distinguishes it from similar-sounding words like "amid" or "amite". Ammites are typically fossilized ammonoids, a group of sea creatures related to the modern-day squid and octopus. Their spiral shells are highly valued by collectors.
