The Fancy Fox has dated this piece to the Georgian era.
1790.

The saucer measures 13.3cm (5 1/4") wide and 3cm (1 1/8") high. The tea bowl measures 8.3cm (3 1/4") wide and 5.3cm (2 1/16") high. The coffee cup is 9cm (3 1/2") rim to handle, 6.3cm (2 5/8") rim tot rim and 6.3cm (2 5/8") high.

Condition is very good; there is a very fine hairline across the lower terminal of the coffee cup and a fleabite inside the foot rim of the bowl. There is also a nick to the saucer foot rim but it appears under glaze. No other issues and surface wear is very light, just a tiny bit of wear to the gilt on the rims in a couple of places.
