tall tree with glossy leaves and purple berries

Hello,

These are the leaves of a tall (~50 ft) tree growing in my neighborhood near Alexandria VA. Does anyone know what it is?

shiny leaves, ~5-10 cm long
green oblong berries gradually turning purple

Thanks for any clues!

 

Might be black gum, Nyssa sylvatica.

 

Very likely black gum!

 

Third vote. Handsome ornamental, perhaps the best shade tree for red fall color.

 

Thanks alot!
