This is 2-way accessory (that can be used as either hair clip or brooch) made of real sunflower.
A whole sunflower, as small as 6-7cm, is specially preserved to keep its fresh color and then hardened three-dimensionally using special resin with high persistence of transparency, which means it rarely turns yellow but holds its clear water color semi-permanently.
The process of hardening such delicate petals of the flower requires a great deal of concentration and is so complicated that it cannot be achieved by machine.
I hope you enjoy the one-and-only, precious gift both from nature and handwork.
