The words “jewel”, “jewellery” and “jewellers” are commonly mispronounced. The “w” should be almost silent, i.e. “jooal”, “jooallery” and “jooalers”.
This was brought home by a story in Mid-Day.com and this picture (credit to Mid-Day):

The Marathi sign board uses the transliteration “jyuwelers”, which should really have been जूलर्स.

There is a good reason a “quote” is spelt differently from “Coat”.
Simple. They are pronounced differently.
“Quote” is pronounced “kwote” (क्वोट).
“Coat” is pronounced “koat” (कोट)
