I bought this beautiful necklace at a local market and have been very intrigued to find out more about it. I have searched the internet extensively.Can anyone tell me if it is by Reveriano Castillo. Does anyone know who the other mark on the back of the necklace is for as it remains a mystery. I would be very grateful if anyone can add any knowledge about the necklace. I have included 3 images below.
Thanks
