THE COMMON MISTAKES WE MAKE WITH OUR JEWELLERY

Searches for Black Friday jewellery deals have exploded, but experts warn that without proper care and insurance, new gems could quickly lose their shine and their value.

With global interest in “Black Friday jewellery” surging more than 400 per cent this month, Australians are diving into the festive gem rush for gifts, upgrades and a little self-reward.

But while the hunt for bargains is fierce, the knowledge gap on jewellery care is costing people dearly.

More than half of jewellery insurance claims relate to accidental damage, overshadowing theft and loss. Put simply, the nation loves buying jewellery but isn’t so great at protecting it.

To help bridge that gap, the luxury specialists at Dawsons Auctioneers have put together a practical guide for new and returning jewellery owners.

GET YOUR JEWELLERY COVERED

Once you’ve bought or unwrapped a new piece, insurance should be top of the to-do list. Residential burglaries rise by 7.3 per cent across the festive season, but theft isn’t the only risk.

Many Australians wrongly believe high-value jewellery is automatically covered under home insurance. If it exceeds set limits, it often isn’t.

Dedicated jewellery insurance covers accidental damage, lost stones and issues during overseas travel, usually at around 1 to 2 per cent of the item’s value.

But valuations must be current, or the payout could plummet.

As Dawsons Auctioneers Managing Director and BBC antiques expert Jonathan Pratt explains: "Gold prices doubled between November 2024 and November 2025, meaning that the replacement cost of gold items has also doubled.

"Unfortunately, thieves sometimes use metal detectors to find precious metals, so the best option is always to install a safe. At the very least, keep your jewellery away from windows and doors, especially on ground level."

WHERE YOU KEEP IT MATTERS

Storing jewellery properly is the simplest way to protect it long-term. Original fitted boxes add value for antique and designer pieces, but they still need to be kept dry and clean to avoid deterioration.

Airtight storage is the golden rule for preventing tarnish, and each piece should always be kept separate.

Pratt says many people underestimate how easily gemstones can damage one another:

“Something that’s often not considered or indicated at the time of purchase is that gemstones have different hardnesses and can scratch. They can scratch each other, and some can chip or scratch while being worn," Mr Pratt said.

"For example, emeralds and aquamarines (both from the beryl gemstone group) are quite soft.

"Most other stones, even quartz, can damage them, so ensure all pieces are stored separately to avoid contact, and don’t wear them whilst getting your hands dirty, especially gardening!”

WEAR AND TEAR: THE HABITS TO AVOID

Jewellery might be made to last, but everyday habits can accelerate its deterioration.

Softer metals can bend if worn constantly, and ring claws catching on clothes is one of the quickest ways to lose a stone. Lotions, creams, and perfumes can tarnish metals and irritate the skin.

Adopting the classic “last on, first off” rule helps reduce accidental knocks and snagging and keeps chemicals at bay.

Mr Pratt adds that some materials are more sensitive than they look: “Jewellery made of organic materials such as natural or cultured pearls can be damaged by chemicals in lotions, cosmetics, and even perfumes.

"Opals, for example, are a 'hydrated-quartz' and they can dry out, causing crazing, so avoid excessive heat and light. Always make sure to know what particular treatment your gems need.”

KEEPING THE SHINE: WHAT WORKS AND WHAT DOESN’T

A little regular cleaning goes a long way. Most jewellery, even the high-end kind, doesn’t need complicated routines.

Warm water, mild dish soap and a soft toothbrush can revive metals and gemstones. Just remember to plug the sink.

For frequently worn pieces, professional cleaning is worth considering. Jewellers can spot loose claws or stones early, and use tools like ultrasonic cleaners that aren’t safe to use at home.
