How do you fix a crack in decorative glass? - crack do coordtrans 2.3

We have a hummingbird blue glass as a gift and now has a jump. Is there a way to repair the crack visible without bulky label? The crack is in and is difficult to achieve. You can use the outside of the seal, but the crack is on the inside, and seems to have spread. We want to repair it because it is a gift. Thank you.
