I'm not exactly sure what this is, a bee, a butterfly, a moth?
 
Anywayyy, this gorgeous thing was originally a mid century stick pin, made in yellow and white gold, and set with cabochon cut rubies and single cut diamonds. We have converted into a sweet, wearable pendant, adding a recycled gold 5mm jump ring. 
 
Tested as 18ct yellow gold and white gold.
