Cleaning Your Jewellery


I always tell people, you would not buy a new car and then never clean it for a whole year. However, with our busy lifestyles, jewellery gets dirty and we do not even notice it. At Knappett Jewellers, customers may drop by our store and have their jewellery cleaned at no charge. We have an ultrasonic cleaner on the main floor. Chains and rings may be cleaned while you wait.

If you have a special occasion to attend, you might want to have your rings refinished and polished to look like new. White gold rings would be rhodium plated and having them cleaned will bring back the beauty they had when they were first purchased.

What is Rhodium Plating?

Rhodium is one of the metals belonging to the platinum group. There are six different metals in the platinum group. Ruthenium, platinum, osmium, iridium, rhodium, and palladium. Rhodium lends itself to electroplating, which makes it perfect for coating the rings. So, in summary, we are actually coating you rings with platinum. This gives a very white, bright shine which will last for several weeks, making them look amazing for your special occasion.
