Lovely vintage brooch made by Miracle.
 5 oval cabochons set in a silver coloured metal more than likely pewter which would be in keeping with their style. The cabochons are a beautiful example of glass imitating turquoise. 
A lovely piece.
 
Miracle jewellery is highly collectable. It was established in 1946 in Birmingham and became a leading British manufacturer of Celtic, Irish and Scottish style jewellery. They are still producing today but they are now based in Cornwall.
