THE STORY: These earrings were bought in Barcelona, Spain. The seller, a multi-generational collector, told me that he got them from Frida Kahlo's niece (her sister's daughter) and that they originally belonged to Frida. I have no way of verifying this information. 
In their own right, besides the supposed provenance, the earrings are very pretty and wearable.
