Squash Overlay Glass Snuff Bottle

I will have to do some repair on the top of this bottle because the cork has come off.
But it's a lovely vegetable of some type (I am just calling it a squash) with delicate carving of the leaves wrapping themselves around it.
It appears to have two overlays - one of cobalt blue and a second one that is a very dark green that appears almost black.
The glass stopper just completes it! You can see how they used a form inside the stopper.
