Since 1869, Prestons have offered exceptional service presenting our customers with an array of both exquisite jewellery and timepieces. Today, our three showrooms all offer incomparable levels of service throughout your entire journey with us. This journey includes the care and maintenance of jewellery and watches – it is important to us that all of your precious items can be preserved and protected to allow you to pass them from generation to generation. Our team have created a few simple guidelines as to how best care for your jewellery below.

There are a few recommendations and guidelines that cover a vast selection of jewellery. Firstly, it is important that at night you try and remove most of your jewellery. Secondly, if you often visit the gym it may be advised that you remove your jewellery – even particularly hard gemstones, such as diamonds, can chip if hit with enough force or at a particular angle. Finally, we would advise that you try to refrain from applying lotions, creams or perfume directly onto your jewellery.

Gold & Platinum Jewellery

It is important for you to examine your gold and platinum jewellery regularly to ensure all settings, such as claws or clasps, are secure.

If your jewellery is white gold, you may also wish to consider having your jewellery re-rhodium plated. Rhodium is a silver-white metallic element that is used to coat white gold, giving it a bright white reflective appearance. This should be done every few years but can vary based on wear.

Diamond Jewellery

When cleaning your diamond jewellery we advise using a soft brush and a small amount of washing up liquid. Our stores would also recommend that you rinse or clean your items over a bowl or tray in case there are any stones or settings loose.

If you are caring for your diamond engagement ring or a setting that features claws, it is also important to check the claws for the safety and security of your stones. Our team would suggest that you have your claws re-tipped, approximately, every eight to ten years.

Precious, Semi-Precious and Coloured Stone Jewellery

Precious and semi-precious stones can be extremely sensitive due to their delicate nature. Many stones such as amethyst, emerald, kunzite, opal, pearl, peridot, tanzanite and tourmaline can be easily abraded as many jewellery cleaning solutions are too harsh for stones such as these.

If you would like your gemstone jewellery cleaned, we would advise you visit your local Prestons showroom who will be able clean your items in store and advise you on the best care options.


If worn often, pearls should be cleaned and restrung professionally every three to five years. Between cleanings, wipe pearls gently with a damp cloth but avoid cleaning – please visit us in-store for this.

Of course, if you are ever unsure, each of our showrooms would be happy to assist you and clean your items in store. If you would like further information regarding jewellery repair and engraving, please visit our dedicated ‘Jewellery Repair & Engraving’ page.
