This set of six hemi-spherical or domed buttons is made of gold that has then been decorated with cream, red, blue and green enamel with pairs of birds surrounded by foliage and with a lower blue enamel border.
The enamel work is typical of Jaipur enamelling of the late 19th century.
The reverse of each has a small gold loop to allow the button to be sewn to a jacket.
Possibly they were intended to have been attached to the front of a sherwani, a knee length coat commonly worn in India in the late 1800s. The sherwani was favoured by elite, educated Indian males.
The buttons are housed in a blue velvet box which might be original.
There are minor losses to the enamel as can be expected but essentially, each is in very fine condition.
