Keeping your jewellery looking at its best at all times needn't be a difficult or expensive task. Here's a few simple tips to follow to preserve your gemstone jewellery's lustre and brilliance.
TRY A JEWELLERY CLEANING CLOTH
More often than not a quick buff with a jewellery cleaning cloth will remove metal tarnishes and keep gemstones looking glossy.
CHECK THE HARDNESS AND PROPERTIES OF GEMSTONES IN YOUR JEWELLERY
A hard precious stone will benefit from a gentle brush with a warm solution whereas softer semi-precious stones may scratch with such treatment. Always ensure you use a gentle, soft bristled brush regardless of the jewellery. Gemstones are categorised by their hardness via the Mohs scale.
KEEP IT COOL
Or temperate to be more precise. Softer semi-precious stones may be vulnerable in excessively hot or cold conditions and also to steam or ultrasonic cleaning. If in doubt contact us.
EVERYTHING IN ITS PLACE
Store your jewellery in its original display box or in a jewellery box and keep it in a safe place.
AVOID EXPOSURE TO COSMETICS, PERFUMES OR CHEMICALS
Try to steer clear of such products when you are wearing your jewellery or have it on display. Some gemstones are sensitive to acidic properties in cleaning products, perfumes, sprays and more. For example, malachite will only need to be buffed with a clean cloth rather than using an ammonia-based soap solution like you may with a diamond. Metal may also become damaged or discoloured with exposure to chemicals such as chlorine and bleach.
PRACTICE MAKES PERFECT
Check your jewellery regularly for dirt or oil build up and clean accordingly.
