regret I've not looked in C.H. as Chris suggests - I hope he's correct and your piece is the age Chris mentions - and I always think those deep curved mitres are a sign of quality - they're not easy to produce.
Some suggestions for you for future possible aids to dating would be............ are there any seeds/stones in the glass...... what is the extent of wear under the foot - always good to post a picture of the underside of the foot anyway, as the number of radial cuts on the star can help to date. Unfortunately, such features have been copied on later pieces and need to be read in conjunction with others - so easy to get it wrong.
Sadly, cut designs such as this very often show some damage to the high parts of the bowl (the midriff and edges of the lid), and the peaks of relief diamonds will also be nicked - after all such items were intended for use.
Of course, if you've paid a lot for this one then you may have a high quality example without damage and with little wear to the foot.
Assume there isn't a spoon cut-out in the lid.
If you do get to read C.H., you'll see the problems caused by later copies, and the replicating of some early C19 features too, and don't over look the States Brilliant period (brilliant as in sparkle - they had a fondness for putting a cut on every square mm of the glass). From memory I think this was the early C20.
Big pain in the rear is that there isn't available a good book on British cut glass - so we have to make do with small snippets spread across a number of volumes.
Your pix are quite good, but you will find that contrast and detail will improve if you photograph against a uniformly dark background.
