Brooch identification - Can you help??

A vintage brooch that I am having a difficult time identifying this vintage jewellery piece. It is lovely with a sugar coating effect in a pale blue and green on to a gold-tone metal within a flower petal shape. This unusual flower brooch I have kept in my own collection as so unusual.

The mark is an upturned horseshoe but the copyright sign is worn and I can not read it. The blue and green brooch also has 7 36 on one side of the back of it.
Can anyone recognize this mark and identify this very pretty flower brooch which I have kept in my own collection, please reply to this post?
Updated July 2014 - still haven't been able to find this jewellery mark but still live in hope!

Up-Update 2019 February - still not able to identify this brooch signature.
