Diamonds need caring to keep them looking at their brilliant best. They should be cleaned at least once a month to keep away the “dullness” that can be caused by skin oils, soap, cosmetics and even cooking grease. The only substance that does not stick to a diamond is water. A clean diamond will reflect better light.When jewellery is worn next to the skin, it will become covered and clogged in oily debris mainly composed of dead skin. Dust and grit become lodged in this. Wearing rings while washing up can also allow a greasy film to coat the backs of stones, and the inside of settings.
The main purpose of cleaning diamond rings is to remove all this greasy debris, and allow light to enter and leave the diamonds, restoring their sparkle.

There are several ways of keeping diamond jewellery clean.

Detergent Bath

The detergent bath is performed with a small bowl of warm suds using any mild liquid detergent. Immerse jewellery pieces in the suds and brush gently with a toothbrush. Rinse under warm running water and pat dry with a soft, lint-free cloth.

Jewellery Cleaner

The quick dip method uses one of the liquid jewellery care products available. Follow the instructions on the kit.

Ultrasonic Cleaners

Jewellery manufacturers and workshops use ultrasonic cleaning tanks. In these, the actual cleaning is performed by the cleaning solution, usually a mixture of ammonia and detergent, the ultrasonics merely provide the agitation to speed up the process. Small domestic ultrasonic cleaners are now available, and many jewellery stores sell them as gift items.
