Hidden gems

This chest holds many secrets;
secrets which have never been told.
It is not to be opened until it is time.
Time for what?
Nobody knows.

The right person, moment or place perhaps?
Perhaps
For the intersection of the trio is rare.
Rare as an apple in an orchard,
entangled in a sea of vines,
vines which prevent it from being found
until the grapes are picked.
