No, we don't usually express "like" in this way. If you say "I favor this necklace", it would mean that you like this necklace better than some other necklace. But in this situation we usually say "I prefer this necklace" instead. I hope this helps.

to favour = to prefer

i guess you can like peachy said.. but i guess most poeple would say something is their favorite.. rather than favour... "this is my favorite necklace."

to favor -as I know- is to prefer you can never express "like" using favor for example :He likes his second daughter .doesn't have the same meaning with :He favors his second daughter.

I agree. "Favo(u)r" used in this way is preferential.
