Gold Aluminum

Gold jewellery can be made with some special (unusual) colour effects, either due to intrinsically coloured intermetallic phases or to surface layers grown by reaction with alloying metals or by deposition techniques. A wide range of colours such as blue, black, brown and purple can be achieved and a number of techniques employed. However, there are some drawbacks: intermetallic colours are intrinsically brittle and surface coatings, by any technique, are liable to be fragile and will spall if knocked, and wear away if rubbed constantly. In simple terms, these are analogous to chemical compounds. Gold jewellery with such colour effects is commercially available and becoming increasingly popular. Some of these exotic colours are obtained by alloying gold with certain other metals to produce special alloy structures known as intermetallic compounds. which possess the desired colour. Solid pieces of coloured gold intermetallics can be made by vacuum melting gold and aluminium in the correct ratio and casting. These are brittle and cannot be worked in the traditional manner. However, they can be applied to a substrate, such as a conventional carat gold, by thermal spraying in a gas jet.

Rose Gold

The precious metals of silver and copper are blended in an alloy with pure gold to create rose gold. Gold and copper are the only coloured metals, all the rest are silvery in colour. Rose gold does not occur in nature. Rose gold is made using a mix of pure gold with alloys including copper. Rose gold has a very subtle and delicate colour that intensifies with age. Common 18k rose gold alloy constituent quantities are: 75wt% gold and 25wt% copper and 75wt% gold, 21wt% copper and 4wt% silver. Rose gold may also vary quite a lot in colour depending on the amount of copper mixed with the gold, 9k rose gold has a darker rose-copper colour than 18k rose gold which has a more subtle rose colour. Tumbaga is a gold and copper alloy.

Purple Gold :: Amethyst Gold :: Violet Gold :: Purple Gold Alloy :: Gold-Aluminum Purple :: Gold-Aluminum Purple

Purple gold is produced when gold and aluminium are alloyed together in the ratio 79:21 by weight. In this ratio they form a gold inter-metallic compound with the chemical formula AuAl2. The gold alloy formed has a purple, amethyst or violet colour. This purple gold alloy can be hallmarked as 18k gold. There are a number of processes that can produce purple gold. Vacuum Melting, Physical Vapour Deposition (PVD), Powder Metallurgy, Vacuum Melting, Diffusion Bonding, Thermal Diffusion, Thermal Spraying, Mix Gold Chloride with Rochelle Salt. The conventional jewellery application of purple gold is in form of cast and ground items, which are set similar to gemstones.

Green Gold

Green gold is not really green. Green gold normally appears as a very subtle, greenish yellow tint rather than what we would normally call green. Blending of silver and pure gold produces the colour tone found in green gold and that we call green gold alloy. Green gold alloy is made by reducing the copper content from an alloy mixture and using just gold and silver. Green gold was known to Lydians from around 2,900 years ago. They knew it as electrum. The ancient Greeks called it gold or white gold, as opposed to refined gold. The greenish colour of green gold is achieved when raising the silver:gold ratio of the alloy. Green gold has been created by a patination technique on copper-containing carat gold alloys. The classic mixture that produces green gold is an alloy of pure yellow gold and pure silver -- though, for rings, harder metals such as zinc are used to make the gold more durable.

Gold Colors

Pure gold does not occur naturally as rose, white, or green gold. Pure 24k gold is only ever one colour: yellow. Any carat (karat) other than 24K gold (pure gold) is called an alloy. Most other pure metals are grey (gray) or silvery white: gold is yellow. This colour is determined by the density of loosely bound electrons which fall into the visible range for gold and copper but in the ultraviolet range for all other metals. Pure, 24k gold is soft. Alloying it with other metals alters its hardness, ductility, melting point and colour (and other properties). In this article we are interested only in the colour variations that occur when varying weight amounts of other metals are used with gold. Pure gold is yellow in colour. Coloured gold has various hues produced by alloying gold with other elements. Gold is mixed with other metals to produce alloys, simply mixtures of two or more metals.

Red Gold

Red gold is a copper-rich alloy of gold. The higher the copper content, the stronger the red colouration. The higher copper content makes the alloy more durable than its yellow or green counterparts.18k red gold is 75wt% fine gold with 25wt% of alloy. 12k red gold alloy is 55wt% copper, 37.5wt% gold, 7.5wt% silver mix. The most common formulation for 12k red gold is 50wt% gold and 50wt% copper. It is also possible to create a much more intense, although brittle, red gold compound using temperature oxidation. The resultant intermetallic red gold is usable for high-end jewellery as an inclusion, as with enamels, rather than as an alloy that can be moulded into any usual jewellery product.

Rose Gold, Red Gold and Pink Gold Alloys

The difference between red gold, rose gold and pink gold alloy is the copper content: the higher the copper content, the stronger the red colouration. By adjusting the proportions of the metals gold, silver and copper, it is possible to vary the colour of gold alloy from very pale yellow, usually called green gold, to a deep red or to a deep gold. It is very simple to produce a gold alloy with a reddish colouration. All that is needed is to increase the proportion of copper in the mixture. To maintain the correct proportion of gold in the alloy, this usually means decreasing the silver content.

Gold: Pink Gold

A common alloy for pink gold is 75wt% gold, 16wt% copper, 9wt% silver by mass. Pink gold is also known as rose gold or red gold. Although the names are often used interchangeably, the difference between red gold, rose gold and pink gold is related to the copper content in the gold alloy. The lower the copper content the more subtle the pink hue. Pink gold will therefore vary quite a bit as copper is reduced and other admix metals are increased in the gold alloy mixture. Pink gold can also be incorporated onto a gold alloy substrate by electrodeposition of a hard, bright, pore-free ductile gold alloy having a pink coloration, useful for decorative purposes. This is effected using an aqueous cyanide-free electroplating bath. Pink gold is a subtle shade in the red spectrum and is well-matched for selection when considering bi- or tr- colour combination in jewellery products.

Artist Review: Daniel Echeverry Lampwork Glass Beads

Daniel Echeverry is a local Cleveland, Ohio glass artist who makes glass lampwork beads for jewelry making.  Daniel is an independent artist who works out of his own studio, and spends his time making tiny small pieces of glass art that can be worn on a bracelet or a necklace, or even sewn into clothing.

Lampworking is done by hand, using a gas/oxygen torch and molten glass to shape beads, marbles, and buttons.  Daniel's beads are made with borosilicate glass using earthy color tones, and clear glass.  In my opinion, Daniel Echeverry is one of the best lampwork artists that I have seen, and his beads are explosions of color and design.
