How To Care for Garnets

Garnets are the birthstone for January. If you already own garnet jewellery or perhaps were given some for your birthday this month, looking after this stone with some simple steps will keep it in good condition for a long time.








Garnets are medium hard, ranging between 6.5 and 7.5 on Moh's Scale. Though exquisite enough for any special occasion, they are durable for everyday wear with certain care. 



However, you should store them separately to other gems so as to avoid scratching each other.

A harder stone such as diamond or topaz can mark the garnet, which in turn, can scrape the softer stones such as turquoise, opal and fluorite. If you can't store them in their own compartment of your jewellery box, then wrap them in cotton cloth.



As with all gemstone jewellery, put your creams, cosmetics and perfume on first to allow them to dry before donning your garnets. Likewise you should take them off first before removing your make up with cleansers.
 
Do not wear garnets when handling any type of chemicals, including household cleaners or when swimming, in the shower or sunbathing. Avoid excessive temperatures. Store them somewhere fairly cool.
To clean them, generally it is ok to use an ultra sonic cleaner, but please avoid steam cleaning. The safest method is to wash in mild soapy water. It should be lukewarm. This method is good for sterling silver, fine silver and gold too. If the stones are grimy you can use a soft toothbrush on them, but preferably not on the precious metal. Use your fingers or a sponge on the silver and gold. Rinse in fresh water then pat the pieces dry with kitchen paper or cotton.

Garnets should last a very long time. Some garnet jewellery was discovered in burial chambers dating back to 3000 BC. Their beauty had not faded. So go on, don't hide your garnets,  but wear and enjoy them.

How to Clean Silver Jewellery (Tips 4)


How to Clean Silver Jewellery

The  4th in my series on Jewellery Care looks at cleaning silver.

Sterling silver, fine silver and Italian silver and many silver plated items will take on a darker patina with time. This is caused by sulphuric compounds in air. It can be beautiful in its own right. However, sometimes it can look very brown and dirty, but it is possible to brighten it up again.

Pre-oxidised silver is deliberately given an accelerated patina that gives it a beautiful, vintage look.  It is very handy if you don’t want to worry about cleaning tarnish. It generally doesn’t need cleaning, other than to wipe with a piece of kitchen paper or uncoated, soft felt cloth to remove oils, cosmetics and grime.  It is not usually recommended to attempt to restore this silver to a shiny state. I tried it once as an experiment and ended up with a dull, matt and dirty looking piece of metal, which wasn’t very pretty.

 Other darker silver metals such as Tibetan Silver (a zinc alloy), Mexican silver etc should not be cleaned with chemicals, acids, bread soda etc. These metals are darker by nature. A barely damp or soft dry cloth will remove grime.

If you want to keep your shiny silver bright as long as possible, there are several measures you can take. Click here: for tips on preventing tarnish on sterling silver and silver plate.

When the metal shows signs of oxidising, catch it early by using a soft, silver cleaning cloth. You can buy these at jewellery outlets and online.  If you haven’t cleaned a piece in some time, it will need more than this.

One of the gentlest ways to clean such silver is to wash in mild, soapy water. This is particularly recommended if you are cleaning stones, amber and pearls set in silver as they won’t withstand harsher cleaning methods. Gold should also be cleaned in this manner by the way. Afterwards, rinse,  pat dry with kitchen paper or a soft cloth and polish the silver with your silver polishing cloth.

Sometimes you need something stronger for resistant tarnish. Silver plate and silver-filled items will generally stand up to a quick bath in a solution of water, lemon and salt (as will natural copper.)  So should sterling silver, but it doesn’t always do the trick so test a tiny area first by dipping a cotton bud into the liquid and rubbing it on. Check for any side effects or if it actually works before subjecting the whole piece to the solution. Do not splash this acidic cleanser on stones, pearls etc. Glass, including seaglass, is fine and in fact, will gleam after the bath. Again, rinse well, dry and polish.
 


If you are sure the piece is sterling silver, you can use a bread soda (bicarbonate of soda) solution. I previously posted how to do this on the Etsy Ireland blog.  For full instructions click here

I hope this helps!

Quick Tips for Jewellery Care (1)

There are several things you can do to keep your favourite pieces of jewellery looking fresh and lovely for longer. I will be posting a series of tips for storing, cleaning and maintaining your baubles and bling. To get the ball rolling, here are 3 quick tips that I hope are of interest:

  • Always apply creams, make-up, perfume etc before you put on your jewellery. The oils and acids in cosmetics and colognes can damage precious metals, gemstones and pearls. Let the lotions and scent soak into your skin before donning your favourite pieces.


  • Jewellery Trees and stands are a pretty way to display your favourite pieces, but they are not always your best friend. I'm very wary of hanging beaded necklaces and bracelets for long periods of time as the stringing materials (tigertail, nylon string, hemp, elastic etc) can stretch or sag, especially if the stones or beads are a little heavy. Best to store flat.


  • Many gemstones hate heat, so storing in a fairly cool place is best. Heat may damage the stone or affect the colour, especially if highly coloured or enhanced.
