Jewellery care



All of Francisca Rendic Jewellery Designer products are handmade using sterling silver. All the jewellery is produced in Australia and made using Australian raw materials.


Remember to store your jewellery in a cool and dry place. Better results if stored your jewellery wrapping the jewellery separately in a moisture-free plastic bag.

The reaction with the chemicals in the environment and body oils causes silver to naturally oxidise. However, it is very easy to keep your silver clean and bright if you know how and use the correct care products.


Use just a polishing cloth, as gentle rubbing and buffing alone will remove mild tarnishing. Polishing cloths are ideal as they are usually impregnated with a polishing compound, last a long time and give an amazing shine.

Clean with soap and warm water and dry very well is another way to clean and remover the grease of the jewellery.

Avoid contact with perfume, hairspray, saltwater and cleaning products.

For oxidised sterling silver, which is intentionally darkened silver made by tarnishing it in a controlled way to increase detail and the appearance of depth in a design. 

Should be careful when cleaning oxidized jewellery though, as too much scrubbing and you will scrub the effect off!


For further polishing, a Customer Sales Service provides services such as cleaning and polishing, re-oxidising, removing scratches, ring re-sizing (depending on the ring design).

But most important of all, wear your 925 sterling silver jewellery. Don’t tuck it away for special occasions, it will not tarnish any less. Take care of it and it will last a lifetime to be passed down as an heirloom for generations to come.

Sterling silver

Francisca Rendic Jewellery Designer uses only sterling silver in her jewellery pieces. Sterling silver is an alloy of silver containing 92.5% by mass of silver and 7.5% by mass of other metals, usually copper.

The sterling silver standard has a minimum millesimal fineness of 925.

Fine silver is 99.9% pure, is generally too soft, therefore it may scratch or bend easily; therefore, the silver is usually alloyed with copper to give it strength while preserving the ductility and appearance of the precious metal.
