Brass, silver and gold
Metals can naturally tarnish over time. You can delay this process by avoiding getting metal items wet. It’s a good idea to remove them before showering, exercise etc. and to avoid exposing them to chemicals such as perfumes, creams and chlorine when swimming. Take metal jewellery off at night, wipe with a clean, dry cloth and store in a box when not being worn. My gold pieces are gold-plated recycled silver. Plating may wear off over time and with use. Following the instructions above will delay this process.

Rope
Rope jewellery is made from 100% recycled cotton and can be gently washed with cold water by hand. Avoid getting any metal clasps wet.
