Gold bars are ingots which are available in a variety of sizes and weights. Gold bars fall into two categories – cast gold bars and minted gold bars.

Minted Gold Bars

Minted gold bars are created by hand cutting gold blanks to precise measurements.

Whether the gold bar is minted or casted the weight and purity is engraved on the top of the bar so that the value of the gold is known. In grams, there are sixteen international weight categories which can be used to create gold bars, which range from five hundred grams to a third of a gram. In ounces, there are eight weight categories, which range from twenty ounces to less than an ounce.

Banks and Traders Measures and Purity Levels

The most common bar which banks hold is the 400 ounce gold bar. It should be noted that these bars actually range from 350 and 430 ounces, but the exact weight is always engraved on the gold bar. Gold bars which are held by banks are almost always of a 99.5 percent purity level. In addition to these bars banks also store in 1 tonne bars, 1 tola bars or 10 tola bars.

Since ancient times people have recognised and cherished gold as a precious commodity. Gold jewellery never goes out of fashion. Unlike many other metals pure gold does not react with other elements to create a residue that accumulates on some of them before transferring to your skin as stain. There are people who are allergic or have staining problems with metals combined with gold, but gold itself is rarely a problem. Gold can be worked into any shape you want even into tiny strands and it does not break easily. One ounce of gold can be hammered and flatten into an ultra thin sheet that is ten feet square.

In the past, gold jewellery was worn only by wealthy people. But during the industrialisation period people of lower social classes became able to afford more than a gold wedding band. Today, people many people around the world are wearing beautiful gold jewellery pieces that their ancestors would have never dreamt of ever owning.

Today gold jewellery is considered to be an important investment for some people. Gold has different types and varieties, thus, it is vital to know how to distinguish between them. What is it with gold jewellery that differentiate a piece from another and why is it so much cheaper similar than similar items? Let us all begin with caratage. Gold carat weight is not the actual weight of gold such as it is with gemstones but the proportion of gold in gold jewellery.

24 carat gold is 100% pure gold and it has a very rich gold colour. Gold jewellery is almost never made from 24 carat gold for one simple reason- 24 carat gold is far too soft and will dent and scratch easily. Often 24 carat gold is used in decorating tableware and wine glasses.

On the other hand 9 carat gold is only 37.5% gold and it contains other metals such as silver and copper that makes up the rest 62.5%. Thus, 9 carat gold looks a little lighter in colour and much less expensive.

Mixing different metals with gold can give it different colours and shades as well. Rich yellow is the original colour of gold. When mixed with white metals such as rhodium and titanium gold jewellery has a white gleam which is similar to platinum. Gold and copper mix turns gold into pinkish hue that is known as rose gold. Traditionally, only yellow gold and rose gold (Eastern Europe) was used but in recent times white gold has become very popular.

When buying gold jewellery, look for the Hallmark stamp of authenticity. This is different from the stamp of the jeweller or manufacturer and it is globally accepted gold authentication stamp that certifies the caratage of gold in jewellery piece.

And while shopping for gold jewellery it is important to choose a jeweller that you can trust. Check the gold prices on different stores before purchasing to establish an average prices of gold item you are after. You might see a gold jewellery piece in another store having almost the same style and type but with less or more expensive. It is important to remember that the price should complement the quality. You cannot get the highest quality piece of gold jewellery at a very cheap price.

Buying gold jewellery online can be great idea too if you have verified the details of the online seller, and it is best if you have already made a purchase from them. It is one way that you can trust the jeweller. In case of online gold purchase look for trust seals on the website and to be sure you might want to contact the certifying organizations.

White gold began to be fashionable in the 1920’s when Platinum, a more expensive metal, began to grow in popularity. White gold is not a naturally occurring metal it is formed from yellow gold and a range of other metals. The process of combining the metals is called alloying. Gold is used in jewellery because it has amazing and unique metallurgic properties. It has high reflective qualities creating its iconic sheen. Two other properties are ductility and malleability, which allow one gram of gold to be beaten out into a sheet measuring one square meter. As gold is so malleable it needs to be alloyed so that it is strong enough to be used in jewellery. Fortunately gold takes very well to alloying.

The carat rating of gold is a description of its purity. In England we commonly use 9 and 18 carat gold, the most popular carat in America is 14, in Eastern countries 22 carat gold is preferred. 24 carat (completely pure) gold is typically used only for banking and investment purposes. White gold is also measured by carat; all gold for jewellery is alloyed so for white gold jewellery the measurement and purity of the gold as defined by its carat is no different. The main difference is likely to be in the price, in order to create white gold yellow gold must be alloyed with specific metals.

Nickel used to be used to create white gold. It is rarely used today because many people find that it causes allergic reactions, normally in the form of a rash. Nickel was often used in the 1920’s because it was a cheap metal that successfully bleached gold.

Silver is inexpensive in comparison to gold. Unfortunately it does not have a good bleaching effect. It is easy to work with so often silver will be one of the metals that is used in the alloying process.

Palladium is a more expensive product than gold, but it performs well as a white gold alloy. The drawbacks are its high melting point and the cost.

The final part of the process, for most white gold jewellery, is rhodium plating. Rhodium is a more expensive metal than gold, but it has a very bright appearance and is highly reflective which makes white gold more desirable. Rhodium plating wears off, so any white gold product needs to be re-rhodium plated at varying intervals depending on wear. You can see a selection of white gold jewellery at http://www.findjewellery.co.uk/all/material-white_gold/f/

The production of white gold jewellery is a more costly process than the production of similar yellow gold jewellery hence why it is generally a more expensive product. When white gold jewellery became popular in the 1920’s it was due to its visual similarity to platinum, which is an even more expensive product. Plus platinum is harder to work with and costs more to process and refine.

Cleaning Jewellery Made From White Gold

It is important to be careful with your white gold jewellery. Under no circumstances should you put it into silver dip. It is likely to react badly with the chemicals and come out looking black. The best thing to do is to gently polish it with a silver polishing cloth. The other thing that will need to be done regularly, is that it will need to be re-rhodiumed to keep it looking new. Earrings and necklaces will often not need to be re-plated, but if you have a white gold ring or a white gold bracelet that you often wear it is likely that it will need to be re-rhodiumed on a fairly regular basis due to constant friction and knocking.
