No, if the gravity seems high, it's probably not finished, it's probably stuck.
That's why you should know your yeast's attenuation, and if you have a ton of unfermentables (from the recipe), so you can guestimate your expected FG. If it hasn't moved in at least three days, and it's in the expected FG, and it's been at least 10 days to 2 weeks, it's safe to bottle.
I'd never bottle before 3 weeks regardless of what the FG was, though. I think it makes clearer beer if I wait a bit.
