I sometimes don't want to use an artifact of which I want to gift like in a few hours. If I got like 2 of them, and 1 is still sharable, there is no way to tell which is not yet gifted if the gift timer is running. And if I used one of them, it would be a waste if that was the one i wanted to gift.

Perhaps put a permanent icon to indicate the artifacts that has already been gifted, whether or not the share timer is still on. This will prevent using artifacts that has yet been shared.

i posted a share recently and noticed the same thing. it would be nice to know which item it is so it is not used or sold.
