Franco link design is based on the curb pattern used by Italian manufacturers. Place two to four curb necklaces flat against each Other and interweave the 'v' shaped links and you will create a Franco link chain. Caring For Your Gold Jewelry To keep gold shining and scratch-free, avoid contact with chlorine and other harsh chemicals. Do not wear jewelry during rough work and be sure to store it in a fabric jewelry box or pouch. To clean gold jewelry, use warm water, a mild soap, and a soft-bristled brush, if needed.
