What Karat Gold Is Bullion?

A gold bullion Perth is an investment asset held as a reserve asset by central banks and governments worldwide, typically stored in bars or ingots.

Karat (in the US) or fineness is an ancient system of measurement used for gemstones that was developed over centuries using seeds from the Carob tree as its standard unit of weight measurement.


Karat (commonly referred to in the UK as carat) is used to measure the purity of selling gold bullion. Pure gold measures 24 karats; most jewelry is composed of less pure gold for various reasons; pure gold being too soft and malleable for everyday applications is often mixed with hard metals such as nickel to make it more robust.

As the higher karat rating indicates, more gold can be found in an alloy. For instance, 18 karat gold contains 75% pure gold with 25% other metals mixed in as filler material. Most investors tend to purchase 22 or 24-karat fineness gold bullion.

Your jewellery or coin should bear its karat stamp, along with other indicators of its authenticity such as a refiner’s seal and serial number. A piece stamped “750” for example indicates it contains 750 parts out of 24 of gold; most jewellers will use this standard quality mark when selling gold items.


When buying gold, two terms that sound alike but mean different things: Karat and Carat. Though similar, these two measures of purity differ as follows: Karat measures purity while Carat is used to describe gem weight.

Gold’s fineness is measured in karats, with hallmarks showing its carat content. In the UK, millesimal fineness measurements use a decimal system that makes interpretation simpler for percentage calculations. As carat rating increases so too does price; each additional carat increases it by 24 times more!


Pure gold can be too soft and malleable for everyday use, so it is often alloyed with harder base metals such as copper to produce a more durable product with increased resistance against tarnishing while simultaneously lowering costs. This process gives gold greater resilience against wear-and-tear while simultaneously decreasing costs.

Most jewellers prefer selling jewellery made from 18 or 14 karat gold as it is less costly than 22 or 24-carat gold and still has an appealing yellow shine.

Understanding the gold purity of your bullion – be it bars or coins – is vital to getting an accurate valuation. This factor should be included when selling or buying it. Purity (also referred to as fineness) has been used as a method to calculate gold content since at least the 15th century, apparently from its Arabic root quart which itself may have come from Greek keratin which means carob seed.


Gold has long been prized as an invaluable precious metal. Due to its durability and stability, it makes gold an excellent material for coins and bullion; additionally it can also be utilized in producing electronic devices and solar cells.

Gold bullion is an investment product widely sought out, due to its purity. Because no impurities affect its price, this makes gold a good way to protect against inflation.

Australian’s Reserve Bank serves as an example of such a national bank, providing both monetary and fiscal policy advice as well as banking services to other state agencies.


22 carat gold tends to be less costly than 24 carat gold because it contains less pure gold, with most of the balance made up of base metals like copper. This composition makes 22 carat gold more durable for people with skin metal allergies while still tarnishing easily – making it less suitable for jewelry use and less likely to appreciate over time.
