USEFUL TIPS FOR CLEANING
ANTIQUE JEWELLERY 


Without Damaging The Precious Metals, Stones And Jewels.

Firstly, although this is slightly off topic for this article, can I offer
one tip that will enable you to enjoy your jewellery for many, many years?
Then, if the worst happens and your beautiful items are stolen in a
burglary, you will stand the best chance of getting them back.

PHOTOGRAPHS
of all your jewellery are a thousand times more useful than a
worded description in a police report.
They don’t have to be
top quality pictures like an instore catalogue, just good enough
to identify them in a line-up. This has proven to be the single,
most important thing you can do, to recover your valuables.
That’s it! My top anti-burglary and insurance claim tip.

The Care and Cleaning of Gold, Silver
and Platinum

Gold and silver are malleable and ductile, chemically stable by themselves
and can be recycled and remodelled into a multitude of items. Gold
retains its lustre
over prolonged periods and will not chip, flake or
corrode. Highly polished silver is the best reflector of light and
retains its strength despite distortion. Unfortunately, this does not mean
that either of them are indestructible.

Gold

Gold is measured in carats and is an indication of its purity. Most of us
discover the importance of gold ranges when we get married, and the
choices are usually from 9 carats (9ct), 18ct, 22ct and 24ct. However, the
purer the gold, the softer it is, until, in its purest form of 24 carats,
it becomes one of the softest metals known.

Purer gold scratches and buckles easily with any kind of abrasion or force
and so is best removed to do work which might damage it. Equally, several
rings on the same finger can often be the cause of a ring suffering deep
scratches or wear, particularly if they are of different carats and
perhaps one or more containing even harder substances like diamonds.

Surprisingly enough, most gold jewellery can be cleaned in warm soapy
water, and any angular areas around stones or the back of the item, which
may be indented, can be reached with an old soft toothbrush, dipped in the
soapy solution. Gold also responds to a light rubbing with a
rouge-impregnated cloth, which gives it a shine, available in most
supermarkets, but high carat golds shouldn’t need it.

18ct gold and higher, will not usually suffer from discolouration or
tarnish and isn’t harmed by contact with household chemicals. However, bleach
and other cleaning products WILL damage lower carat golds
as they
aren’t so pure (being alloys of metals) and are therefore much more prone
to attack by corrosive chemicals.

Storing Silver

When putting silver into storage, it’s not necessary to clean or polish
it. After prolonged storage, it will need cleaning anyway. Don’t use
ordinary newspaper to wrap the silver, nor use elastic bands to bind
several pieces together. After a while the rubber will bond to the silver
as the band deteriorates and rots, leaving a stain, as will newspaper.
Instead, use acid-free paper to wrap items and store where it’s not damp.

Slightly tarnished sterling silver will easily renew to a bright polish by
simply rubbing or buffing with a soft cloth. When an item is heavily
tarnished then a proprietary silver cleaning solution, such as Goddard’s
Silver Dip will always do the trick.

To remove heavy tarnish there are many liquids and creams available that
are rubbed or smeared on and polished off again with a soft cloth. Many
have names that include the terms, “long term”, “tarnish
resistant” or “long shine”. This means they contain a
chemical that leaves a protective layer on the silver, which reduces its
direct contact with the air. Cutlery should therefore be washed thoroughly
before use.

A WARNING ABOUT SILVER PLATE! Always use the least abrasive option
when dealing with silver plate. Over enthusiastic rubbing will remove the
silver to reveal the base metal, especially on external corners and the
rims of lids etc. Any trip to any antiques fair will reveal many, many
items that have suffered this fairly tragic fate, which can be expensive
to repair.

The Care and Cleaning of Diamonds and
Gemstones

Perhaps the most important thing to bear in mind here is the potential for
loss. Always use a bowl of water to clean your jewellery, not the sink. If
you stand the bowl in the sink, put the plug in first, and don’t remove it
again until you’re sure you’ve got all the pieces you started with. It
might sound obvious, but you wouldn’t believe how much jewellery goes down
the drain!

Firstly, check the gemstone or diamond is secure in its claw mounting.
Hold the item in one hand and use a fingernail to just touch the diamond.
If it’s loose you’ll see it rock or move. This will need to be repaired by
your jeweller first, who will tighten the claws. An old soft toothbrush
and warm soapy water is ideal to remove the grease, dust, grit and dead
skin that fills the gaps and indentations around the stone anchors of a
ring or other item of jewellery. This works equally well for almost all
types of gemstone, including, ruby, emerald and sapphire.

A gentle brush, even an artists brush is infinitely preferable to using a
cloth from which threads can be snagged and pulled. If a thread gets
caught in a claw, it can bend or weaken the grip of the claw and stones
can be lost weeks or months later.

Once again check the stone for movement, just to make sure it wasn’t
the dirt holding it in place
. It should now be gleaming again with a
nice new sparkle!

 

 BE AWARE! That some stones are quite ‘soft’ and others are
particularly absorbent. Gemstones that fall into this category are;
pearls, ivory, coral, turquoise, opal and amber. Care must be exercised
when cleaning not to scratch them or leave them soaking. They are also
best stored in separate compartments of a jewellery box.

The Care and Cleaning of Pearls

Pearls are of particular concern because any damage usually results in
discolouration and/or a reduction of lustre. They can be affected by
perfume, hairspray, deodorant creams and sprays, makeup, skin lotions and
nail polish remover.
Put pearls on AFTER using any of these products and after sufficient
drying time for sprays and creams. Just wipe your pearls off with a soft
damp cloth before putting them away, so that any residue doesn’t remain to
damage them in storage.


General Safeguards

Whilst your jewellery is not being worn, it is best stored in a lined box
or soft pouch, similar too, if not the one you had, when the item was
purchased. Necklaces shouldn’t be allowed to become tangled and metal or
diamonds can easily scratch other metals or plate, just by being next to
each other.

This can ruin or dull a polished surface very quickly, with the obvious
disappointment and loss in value that will be the result.

I also would advise against wearing your jewellery whilst gardening, doing
housework, or playing any kind of sport, in particular swimming. Jewellery
is particularly susceptible to damage from the effects of chemicals
present in perfume, hairspray, nail polish remover and deodorant.

If a lost ring or earring is trodden into the lawn, it can be a hundred
years before it’s found. Likewise, rings can all too easily slip off soapy
or sweaty hands and be lost forever.

Your local swimming baths are especially destructive to expensive
jewellery as the chlorine found in the water can cause surface damage.
Gold and silver hate chlorine which was an active ingredient introduced
during the refining process to separate the base metals in the melting
crucible.

I apologise to our American friends who will object to my spelling of
jewelry as jewellery. We must, in this instance, agree to differ and blame
it on the pond. Thanks 🙂
