GOLD

 

Gold will not tarnish, rust, or decay. Though it is a durable substance, it is also the most malleable of all metals. Gold is such a flexible and elastic material, that a single ounce can be hammered into 300 square feet. The top three gold producing countries are South Africa, United States, and Australia, respectively. Gold is one of the most desired metals across the world.

 

Measurement

 

Karats (with a "K") are actually a measure of the percentage of gold to alloy contained in gold jewellery. Pure gold, the 24-karat variety, is too soft to make quality jewellery out of. So it's mixed with other alloy metals such as copper and silver, for strength. The purity of gold is measured in carats.

 

24 karat = 100% gold
18 karat = 75.0% gold
14 karat = 58.5% gold
10 karat = 41.7% gold

 

It is important when buying a gold piece of jewellery to take into consideration how much the jewellery will be worn. If it is believed that the piece will be worn every day, a lower karat would be more beneficial than a higher karat. For those with allergies the higher the concentration of nickel in a piece of gold jewellery, the more likely it is that someone with allergies will react to the piece. Bevilles stock a wide variety of diffeent types of gold colours, including:

 

Yellow gold is the most common of the three colours because gold comes out of the ground yellow. Yellow gold will vary in shades depending on which country it originates from.

 

White gold is a little more complex than yellow gold as pure gold is yellow; the colour white comes from other elements within the metal. White gold is plated with rhodium. With time the rhodium can fade away, making the white gold jewellery appear dull. To restore white gold can be re-dipped with rhodium by Bevilles Jewellers, usually at a low cost.

 

Rose gold appears to have a pinkish hue because it is more concentrated with copper.

 

Two Tone. Some jewellery is offered in two, or even three, tones of gold. This usually means it combines white gold with yellow gold to give the piece a unique colour appeal.

 

Silver Filled Jewellery Bevilles have a huge range of 9ct Sterling Silver-Filled Jewellery. These pieces are not gold plated; therefore the gold content does not 'rub off' as it would in a plated piece. Silver-filled jewellery is 9ct white, yellow or rose gold tubing, filled with either sterling silver mesh, wire or solid sterling silver.
Filled jewellery is inherently heavier than hollow jewellery, as the pieces are considered 'solid' once filled with the silver lining. This filling increases the durability and longevity of the jewellery. Silver Filled Jewellery does however require a certain level of care, as the jewellery will still experience 'normal wear and tear' over time. Silver filled items have the similar properties as solid gold pieces but sell for a fraction of the price.

 

Caring for your Gold Jewellery

All Gold jewellery requires some level of care to ensure it is always looking its best. Cleaning the item from time to time, using Gold Jewellery Cleaner, rinsing in warm water and then polishing with a Gold Polishing Cloth (both available from Bevilles) will ensure your precious jewellery is clean and free from skin's oils, cosmetics and other chemicals that can reduce the lustre of the piece.

Chlorine, bleach and other household chemicals can damage Gold, so they should be avoided. All jewellery should be removed before sleep, bathing or any other physical activity and be stored separately to avoid accidental damage or scratching. Bevilles Jewellers recommend that all Gold jewellery be professionally inspected, cleaned and polished annually. In the case of White Gold get your rhodium re-plated at least once a year, to ensure the item is always looking its best.

 

 

SILVER

 

Pure silver is relatively soft and very malleable therefore can easily be damaged if used in jewellery in its pure form. In order to produce a more durable product, it is combined with other metals creating an ‘alloy’ or blend called Sterling Silver.

Sterling Silver most commonly consists of 92.5% pure silver and 7.5% copper. Although any metal can make up the 7.5% non-silver portion of Sterling, centuries of experimentation have shown copper to be its best companion, improving the metal's hardness and durability without affecting its beautiful white colour.

Sterling silver blend

Silver Blend Name Typical Stamp OR Hallmark Fineness Minimum % Pure Silver Minimum % Other Metals
Pure Silver (Not a Blend) Fine Silver Fine Silver / Fine 999 / 1000 99.9% 00.1%
Sterling Silver Alloy Sterling Silver Sterling Silver / Sterling / Ster / 925 925 / 1000 92.5% 7.5%

 

All Sterling Silver jewellery requires some level of care to ensure it is always looking its best. Care should be taken to prevent tarnish build-up on Sterling Silver. Chlorine, bleach and other household chemicals can damage Sterling Silver and accelerate tarnishing, so this should be avoided.

 

 

STAINLESS STEEL

 

Stainless steel is defined as a steel alloy with a minimum of 11.5% chromium content. Stainless steel does not stain, corrode or rust as easily as ordinary steel, but it is not stain-proof.

 

Stainless Steel’s use in jewellery, including watches, dates back to the early 1900’s. Stainless steel is renowned for its trendy appearance and styling (being available in different colours and surface finishes from white through to dark grey, and a polished or matt finish). Its unquestionable strength, durability affordability have kept it in the spotlight.

 

Stainless steel, like any other metal surface will scratch and mark with wear. Stainless steel can be lightly buffed by some jewellers and / or watchmakers; however unlike gold, silver or platinum, these marks will not be removed completely due to Stainless steel’s hardness. Due to this, Stainless steel cannot be re-sized either.
