jewelry
Sure, sure, it is made by a jeweler but the last [e] in this case flees the scene like a jewel thief. However, if you prefer British spelling, remember to double the [l]: "jeweller," "jewellery."
judgment
Traditionally, the word has been spelled judgment in all forms of the English language. However, the spelling judgement (with e added) largely replaced judgment in the United Kingdom in a non-legal context. In the context of the law, however, judgment is preferred. This spelling change contrasts with other similar spelling changes made in American English, which were rejected in the UK. In the US at least, judgment is still preferred and judgement is considered incorrect by many American style guides.
