Freeform crochet jewelry - brooches and brooch / necklace

I have finished some crochet brooches. All of them made of mercerized cotton yarn with thin hook #1 in freeform technique.

Sometimes I have idea how it may look sometimes I just crochet and don't know how it turn out. So these small crochet jewelries is really unique and one-of-a-kind and impossible to make a copy. The secure brooch pin is on the back of brooch. The first brooch includes crochet cord to wear like necklace-pendant.
