Jewellery is produced with care and made from valuable materials. For jewellery to last generations it will require checking and maintenance. We recommend that you have your jewellery cleaned and inspected regularly.
Here are some easy methods you may do to prolong the life of your jewellery in your daily life.
– Jewellery can be harmed by perfume, hairspray, makeup and chemicals. Ensure that you put on your gemstone jewellery last when getting ready for the day.
– Remove jewellery before doing any household and outdoor chores or exercise, etc.
– Avoid dropping or knocking your pieces on hard surfaces or extreme temperature changes.
– Make sure that your jewellery is one of the first items you take off when getting changed to avoid being caught in clothing, etc.
– For best results, gently wash away any makeup and skin oils from your jewellery. Opals and pearls can be gently cleaned by using a clean soft cloth.
– Your jewellery should be kept in separate sections of your jewellery box to prevent contact with other items and scratches.
– To keep your jewellery protected and looking its best, we advise removing all pieces before showering.
– Inlay, doublet & triplet opals should not be immersed in water.
– Pearls should ideally be restrung every two years.
