Vintage Portuguese silver cannetille jewelry set

This gorgeous parure includes necklace, bracelet and screw back earrings. Each substantial silver piece features stunning and intricate floral cannetille work. The earrings are a single flower, attached to a screw-back finding (like clip-ons, they don't go through a piercing hole). The bracelet has 6 flowers attached with oblong jump rings. It secures with an old spring ring clasp. The necklace features one larger flower and four smaller flowers on each side. All are fixed station style on the oblong rings that make up the lower half of the chain. The upper half of the chain is made of smaller round links. There are hallmarks on each piece, and makers marks on the necklace and bracelet. The hallmark bears an eagle's head facing left above the number 833 both contained in an elongated hexagon. This mark was used from 1938 to 1984 by the control office of Porto, Portugal verifying the purity of the silver. The maker's mark is harder to ascertain; I think I see a vine and the letter G but it's hard to make out even with my loupe. The set is in amazing condition. I am happy to provide more photos or answer any questions.
