The bowl of the cup is most probably Indian, from Cambay on the west coast, which was a major port in the 17th Century and the centre of the Indian hardstone industry, which still thrives there today. 11cm wide over handle.
The later mounts are probably English and mid 18th Century, as teacups with a single handle did not appear until the 1740s.
It is very similar to many of the hardstone bowls which appear in the 1690 Devonshire Schedule, but is not specifically itemised in the inventory which recorded a huge bequest from Elizabeth, Countess of Devonshire (1619-1689), to her daughter Anne, Countess of Exeter (1649-1703).
