Micro-mosaic floral brooch with converter to wear as a pendant.
Brooch will measure 1 1/2" across.
The pin back will look similar to the last photo, and I will include a chain If you choose that option.
A pearl or peridot collar is an option--the flower can still be a brooch, with a different type of converter if you choose one of the collar options. The pearls are genuine seed pearls, the peridot is genuine stone. The magnetic clasp is where the flower sits.
