Cleaning semi precious jewellery & tips for looking after different gemsAll semi precious gemstone jewellery gets dirty over time including modern and old gem jewellery.
This is a short guide to cleaning your gemstone pieces and for their care and protection when stored, but if ever in doubt then consult a specialist jeweler.
Ideally you should wipe your piece of gemstone jewellery with a moistened soft lint free cloth after wear to remove any oil and salts. Allow to dry thoroughly before storage. A cotton bud can also be used for small gemstones. Dip into water and blot first on a piece of tissue. Wipe dry with the other dry bud end.
But just occasionally you should try to clean it a bit more thoroughly with a cleaning solution or by a machine method such as steam or ultrasonic cleaning. Care should be taken with gemstones though and the following is a guide to the care of individual stones that are prong set into a piece of jewellery and not just glued in place. Clean the gems first and then treat the metal as described on our cleaning jewellery information section.
Normal care of Alexandrite jewellery includes moistened cloth wiping and can use a steam cleaner but NOT a ultrasonic cleaner.
Take extra care not to expose this gemstone for long periods to sunlight as it can fade the amethyst colour. Wipe with a moist cloth also suitable with the use of a steam cleaner but NOT an ultrasonic cleaner.
Wipe Aquamarine with a moistened cloth and dry well. It is also suitable with steam cleaning. Not to use an ultrasonic cleaner though.
Wipe the Citrine gems with a moist cloth. Suitable with steam cleaning recommended but NOT the use of an ultrasonic cleaner.
Both clear and colour enhanced diamonds will benefit from routine wipe care. They can be cleaned more thoroughly in a steam and an ultrasonic cleaner.
Only recommended cleaning emeralds with a wipe cleaning method. NOT to be cleaned in a steam or ultrasonic cleaner.
Normal wipe care with NO steam or ultrasonic cleaning. This gemstone does not like extremes of heat and will crack if its structural water is loss. So keep away from drying condition.
Again wipe clean only with a moist cloth drying after well. They can also be rinsed under water and then dried by gently patting with a dry cloth. This rinsing method is not recommended for a necklace as the string will deteriorate over time more rapidly. the same Above methods can be used for vintage fake pearls, but test in a place that can not be seen first - that the pearl coating will not deteriorate and come off when using a moist method. Some of the fish scale coated jewellery will do this - so be very careful. The best solution to keeping real pearls in a good condition is to wear, as the natural body oils protect them.See our guide to faux or simulated pearl cleaning.
