Production of GIORRE jewelry: Each GIORRE product has been designed and manufactured in Poland. An extremely talented artist known as Rose Sanders (graduate of the Academy of Fine Arts in Krakow) is responsible for the design of our products. We use only the highest quality semi-finished 925 sterling silver components made by Polish manufacturer SILVEXCRAFT. GIORRE product protection: GIORRE products are covered (depending on the chosen option) with layer of bright rhodium, black rhodium, 18K rose gold or 24K lub 18K yellow gold. Galvanic process which silver jewelry is subjected to protects against oxidation (blackening and yellowing).
