How to look after gemstones
Most gemstones require some basic levels of care to protect them from colour changes, breakages and long-term damage. Even a diamond can chip is struck with sufficient force and many types of coloured stones may fade if not cared for properly.
We would recommend the following simple precautions to take care of your gemstone jewellery:
- Protect your jewellery from hard knocks or abrasive materials, being careful to remove your jewellery when doing manual work
- Avoid exposing your jewellery to any sudden temperature changes, particularly in sunlight, saunas or swimming pools
- Be careful of any contact with chemicals and solvents, as well as everyday lotions, hair bleach and perfumes
Some gemstones such as amethyst, emerald, opal, tanzanite, tourmaline and turquoise are particulary susceptible to changes in heat. Enamel is sensitive to hard impacts and solvents.
Diamonds and other gemstones will sparkle more when cleaned on a regular basis. Over time the accumulation of natural body oils and dirt can dull the shine and brilliance of a gemstone.
With a non-metallic soft brush, we recommend gently cleaning the gemstone in warm and very slightly soapy water. Pat dry with a lint free cloth. Porous gemstones such as emeralds should be cleaned gently with a soft, dry cloth.
Avoid using household cleaner and other harmful chemicals unless these have been recommended and the cleaning is performed by a jeweller.
Use of ultrasonic cleaners
Ultrasonic cleaners are sometimes used by jewellers to create sound waves that can help dislodge and remove dirt. Please check the settings of any gemstones cleaned with ultrasonics as the waves can sometimes weaken the gem's prongs and clasps.
Ultrasonic cleaners should also only be used with some gemstones with caution or avoided altogether. We do not recommend their use with pearl jewellery as the ultrasonic waves can damage the nacre of the pearl.
Wrapping individual pieces of jewellery in tissue or in separate pouches will help gemstones or polished metalwork from becoming scratched.
