With the launch of our new range of gems, pearls and Semi Precious Stone Chips this month we thought we’d take a look at the process of selecting stones using colour.

 

The Earth yields up a rich variety of gemstones that can be used in jewellery making, with every hue and colour imaginable available to incorporate into stunning pieces that will compliment any outfit. The choice of which gemstone to include in a piece is purely down to the individual and is subject to all kinds of influences including birthdate, fashion or even superstition.

Birthstones are a good place to start. Each zodiac sign has a particular gemstone associated with it, and giving someone a piece of jewellery that incorporates that stone shows the recipient that much more thought has gone into the piece. The gemstones range from the lavish such as sapphires, emeralds and rubies, to the more subtle like moonstone and lapis lazuli. Because of the sheer range of gemstones available, you can spend as little or as much as you like and still have a beautiful piece of jewellery with a hidden meaning, which will be cherished by the recipient.

 

Breaking down gemstones by colour is also an alternative. If you like red but can’t afford to buy a high quality ruby, then you could look at cheaper alternatives such as garnets or spinel. Spinel can range in colour to a delicate pink through to a deep red and can look every bit as stunning as a ruby. Garnets offer a deeper shade of red with hints of violet and purple in them. They’re popular in eastern jewellery and can be used to produce exotic looking jewellery at a fraction of the cost of most rubies.

 

For blue stones, sapphires are the first choice, but even though these range in colour, quality and price, there are other alternatives. A particular favourite is the deep royal blue of lapis lazuli, which is often flecked with gold within the stone. This can produce a stunning effect with gold findings. Lapis can also be bought as beads as well as cabochons, meaning that the stone can be used in necklaces or as a setting for a ring, for example. Kunzite is another alternative that has a violet tint and is a relatively cheap alternative to precious gemstones such as sapphires.

 

Not strictly a gemstone but still valued highly in jewellery making, amber is a perennial favourite. Its warm, golden tone compliments silver findings perfectly and it has a honey-like lustre that is hard to resist. It can be a difficult gem to work with as it is very soft, but the results it produces are well worth the effort. Baltic amber is the most highly prized, but Middle Eastern amber can range in tone from a golden yellow to a deep red.

 

The most obvious green gemstone to go for is emerald, and surprisingly these can be far less expensive than you first think. Again, quality stones will cost more, but if you’re willing and capable of doing a little work to refine a lower quality stone the effects can still be beautiful. Peridot is a cheaper alternative and is a much paler green with a translucency that is extremely delicate and effective for use with small findings.

 

The opal carries a great deal of superstition with it, but is probably one of the most beautiful gemstones to work with. It ranges from a milky white to deep blue or even the rare ‘fire opal’, which is like a small firework captured in stone. Its ability to catch the light and produce a rainbow of colours is dazzling, and opal retains its popularity even today.

 

There are thousands of gemstones to choose from, and cooksongold.com carries  a full selection, ranging from emeralds and rubies right through to cheaper but no less beautiful alternatives. Don’t be afraid of including gemstones in your jewellery making – the results can be inspiring!

Why not combine a visit to the Cookson Trade Counter with a visit to the Museum of the Jewellery Quarter.

The Museum has a preserved jewellery workshop offering a unique glimpse of working life in Birmingham’s famous Jewellery Quarter. For more than eighty years Smith and Pepper produced jewellery from this workshop, founded in 1899. Explore this extraordinary industrial time capsule on a lively guided tour. Here you will find things left as they were on Smith and Pepper’s last working day.

The museum tells the story of jewellery making in Birmingham. The Jewellery Quarter gained its distinctive identity in the 19th century when Birmingham was known as the ‘Workshop of the World’. Today the city is still very much at the forefront of jewellery manufacture in Britain.

You can get a feel for this great industrial past and modern  jewellery trade as you wander through the Quarter’s tight-knit street, lined with jewellery shops, makers’ workshops and distinctive historic factories.

Silver Clay Explained – Precious Metal Clay and Art Clay Silver

Tuesday, March 3rd, 2009

If you’d like to make a general comment regarding this article or post a question to the Cookson team please click here

Last year we introduced Precious Metal Clay (PMC), and we had a great response to the range. Designers loved PMC’s flexibility, giving them the ability to create unique designs using a new material. Throughout 2008 we had many requests to stock Art Clay Silver, so we are now pleased to be offering both ranges!

As part of the launch, this week we thought we should focus on these two great products and outline what metal clay is, how it works and the main differences between PMC & Art Clay.


Precious Metal Clay

Precious Metal Clay

Metal clays allow jewellers to work with a material that is as malleable as ordinary modelling clay but produces fine (almost pure) silver jewellery of exquisite intricacy and beauty. Once polished it has a lustre and shine that is easily comparable to cast silver and because of the development of the products over the last few years shrinkage is now no longer an issue. The type used depends on personal preference as both types have their advantages, but incorporating metal clays into your jewellery design gives you a new medium to explore with beautiful results.

What is Metal Clay?

Metal clay is a suspension of tiny particles of metal in a clay binder, which can be used to make jewellery, beads and small findings. The beauty of metal clay is that it can be manipulated in the same way as any modelling clay, but once fired the binding agents are burnt off leaving the metal form intact. Although there is a certain amount of shrinkage (between 10-15% for the more modern versions), very fine detail can be achieved, including impressions that would require casting in any other method of metalwork.

 


Precious Metal Clay (PMC)

Silver metal clay results in objects containing almost pure silver (also known as fine silver) which is ideal for enamelling. There are two popular brands available – Precious Metal Clay (also known as PMC) and Art Clay Silver (ACS). Precious Metal Clay was developed in the early 1990’s in Japan and consists of microscopic particles of pure silver (or fine gold powder) and a water-soluble binder which burns off during firing. The original formula of PMC (now called ‘Standard’) has to be fired in a kiln at a temperature of 898°C/650F and has a high shrinkage rate of around 30%. Two additional versions were later developed called PMC+, which can be fired at 810°C/1490F and PMC3, which can be fired at temperatures as low as 593°C/1100F. Both of these later versions of PMC have much lower shrinkage rates, allowing much finer detail to be worked into designs.

 


Art Clay Silver

Art Clay Silver (ACS) was also developed in Japan and is similar in consistency to PMC+. The main difference with Art Clay is that it is more suited to be fired using a hand-held torch or gas oven. Because of subtle differences in the binder components and the longer firing times, Art Clay Silver benefited from having a considerably lower shrinkage percentage – only 8-10%. This means that ACS can be worked in more detail without any loss of definition in fine work. Art Clay Slow Dry was introduced soon after, which has a much longer working time before requiring firing, allowing intricate work to be moulded into the clay with no loss of malleability.

NEW Art Clay

NEW Art Clay

Art Clay 650 and Art Clay 650 Slow Dry are now becoming increasingly popular, as not only do they have a longer working time but can be fired at temperatures as low as 650°C/1200F. This allows jewellers to incorporate glass and Sterling Silver into the designs without fear of damaging the components. The manufacturers of ACS have also introduced Oil Paste, a product only used on fired metal clay or milled fine silver, and Overlay Paste which is designed for drawing designs onto glass and porcelain. These two products have allowed the use of metal clay products to be incorporated into a whole new range of designs and mediums, expanding the potential of this product.

Metal clays allow jewellers to work with a material that is as malleable as ordinary modelling clay but produces fine (almost pure) silver jewellery of exquisite intricacy and beauty. Once polished it has a lustre and shine that is easily comparable to cast silver and because of the development of the products over the last few years shrinkage is now no longer an issue. The type used depends on personal preference as both types have their advantages, but incorporating metal clays into your jewellery design gives you a new medium to explore with beautiful results.
