i found 3 of the most popular spellings,
jewelry = 51,000,000 (google matches)
jewellery = 26,500,000
jewellry = 107,000
I have got the baby of them, though 108,000 is fair.
Funnily enough, google doesnt prompt for the usual "did you mean ****" when searching for any of these, which is normally the case for typos. Maybe these spellings are accepted for the same term.
Time will tell if I have a worthy org though
