Gold

Gold had been known to mankind for thousands of years, as evidenced by numerous ancient jewels found by archeologists.

Gold is a part of precious metals group, due to its ductility and, of course, thanks to its lustre. In gold jewellery manufacturing, a certain ratio of other metals gets added to pure gold, which endows it with the required properties and colour. The resulting mixture of metals is called an alloy.

 

Assay is the content of pure precious metal per 1 kilo of alloy. Thus, 585 ° gold contains 585 grams of pure gold, where the rest are other metal impurities. Gold fineness can also be expressed in karats. Pure 100% gold is considered to be 24 karats, therefore 14k gold contains approximately 58% of pure gold in alloy (14 divided by 24 = 58,3 ).

Pure gold is extremely pliable and soft metal. The thinnest 3 km long wire can be drawn out of just 1 gram of gold. By hammering gold into finest thin sheet, thinner than a human hair, we get gold leaf. Gold leaves are widely used in decoration, for gilding large-scale objects: such as pieces of furniture and interior, sculptures and even domes. However, people do not stop there and gold leaves are now used in culinary and even medicine. Not only most luxurious drinks and deserts are priviledged to be complemented with gold flakes. There are examples of gold sprinkled fast food, sush as pizzas, burgers etc. Speaking about medicine, gold is one of the components of Precious Tibetan pills. It is believed that such pills detoxify the body and restore strength and vivacity.

 

White gold.

​Many people wrongly believe white gold is platinum. In fact, white gold- is an alloy with other white metals (such as palladium, silver, etc.). Despite its name, white gold is not always perfectly white, and it may have yellowish or even pinkish hue. In such cases, white gold jewellery gets rhodium plated. Rhodium is a hard metal and has a distinct silvery-white colour. Coated with rhodium jewellery is protected from oxidation and has an attractive glossy shine.

Red and Rose gold.

Red gold has a reddish colour due to high percentage of copper. It is tought that red gold is more durable and long-lasting, and practically does not tarnish. This type of gold is popular within Eastern Europe and CIS. Red gold was also known as Russian gold, however the term is now obsolete. Depending on copper percentage gold colour can vary from red to rose tone.

 

Yellow gold.

Yellow gold is jewelcrafting's classic, it has an intense yellow or lemon colour which is acieved by adding silver and copper to the alloy. Yellow gold has firmly taken European jewellery retail market. Westerners give preference to wearring yellow gold alloys as they consider it to be "real", in addition, it is associated with the Royal Crown colour. Many leading designers choose yellow gold in creating sumptuous and luxurious pieces of jewellery.

Black gold.

Black gold can be obtained in several ways. The easiest and most common option is black rhodium or ruthenium plating. However, the progress goes on and black coloured gold can be achieved with a laser, that creates nanostructures on the surface. Processed gold does not reflect any light, which is why it looks completely black. Pieces, crafted out of black gold are eye-cathing and always look elegant, it is easily to combined with other precious metals and of course precious stones.
