What is Sterling Silver?

The official designation of “Sterling” to a piece of Silver indicates that it contains at least 92.5% of pure Silver. The remaining 7.5% comprises of other metal alloys, most commonly copper. Although it may seem that “pure” Silver would be most desirable, that’s not actually the case. Metal alloys with a Silver content of more than 92.5% are too pliable to be used without suffering from dents and damage.

Why does Sterling Silver Tarnish?

Sterling Silver will tarnish. This is not a defect but the result of a natural chemical process that occurs when Sterling Silver is exposed to materials containing sulphur and acids (such as those found in sweat and skin oils). Anything, from medication, perfume or the ph balance of a person’s skin, can affect the extent of tarnishing to a piece of jewellery. Humid environments will also accelerate tarnishing. It is important to clean and care for your jewellery regularly to prevent any tarnish or discolouration from occurring.

Why Does New Zealand Mint Rodium Plate?

New Zealand Mint have produced & sold high quality jewellery for over 40yrs. We wish to maintain our reputation as suppliers of superior quality product and hence adding value by providing silver jewellery with rhodium plating. Because rhodium is a “noble metal” & inert, it withstands corrosion under nearly all environmental conditions.

Rhodium is very hard, durable, near scratch resistant, and will preserve silver jewellery pieces beyond their normal life span plus it has the advantage of being hypoallergenic.
