    1.1, Unable To Identify the Purity of Gold in a Simple Way?

    Every investor in the market for precious stones knows that knowledge is power. Considering the exorbitant prices of these metals today, you cannot afford to make mistakes. Being able to differentiate the fake precious metals from the real precious metals will help you steer clear of arguments, save time and money.

    Needless to say, there are malicious, counterfeits, and prohibited precious stones circulating everywhere in the market. It is, therefore, very fundamental that you understand real gold’s physical and chemical properties. Consider the accurate gold tests below that you can do at home.

    • Gold cannot be oxidized. Unlike metals like copper, silver, aluminum, and brass, it does not tarnish or rust when oxidized.
    • Gold is nonmagnetic. Gold has very weak magnetic properties and cannot be magnetized like iron, cobalt, and nickel. If your ‘gold metal’ responds to magnetic, it is fake gold.
    • Gold possesses a high electrical conductivity. It also an effective thermal conductor. Although copper and silver are the best conductors, gold outlasts them because it is resistant to tarnish and it does not corrode with ease. As a result, gold is very vital in electronics.
    • Gold is a soft metal that can be cut using a sharp object.
    • Exceptional ductility. It can be outstretched into the thinnest circuit wires without breaking. You can draw one ounce of gold into 80km of thin gold wire, five microns of a meter thick.
    • High malleability. Gold is an extremely malleable metal that you can flatten into incredibly thin sheets. A single ounce of gold can be hammered into a thin sheet measuring 5 meters on a side. Gold sheets, also called gold leafs, are used in arts and teeth fillings.
    • Only dissolves in nitro-hydrochloric acid. Gold does not dissolve when subjected to treatment with a single acid. However, when nitro-hydrochloric acid is prepared by mixing nitric acid with hydrochloric acid to treat gold, it dissolves.

    1.2, Do You Really Know That Precious Metals are Real?

    Have you ever wondered whether the precious market is worth the puffery and if precious metals really exist? Research shows that although rare, precious metals have existed since historical times, they were as significant as currency.

    • 10 Karats = 42% pure gold
    • 9 Karats = 37.8% pure gold
    • 8 Karats= 33.75% Pure gold

    1.3, Impure Gold Types That Cannot Be Identified By Simple Method

    The value of gold, to a great extent, rests on its purity. The presence of minimal amounts of some naturally occurring elements can contaminate pure gold and lessen its value. Some natural processes exist for gold contamination to occur, and one gold extraction method, per se, does not have a distinctive benefit over the other with reference to purity. The most common impurity in fine gold is silver. Other impurities that may be existing in small but noteworthy amounts are iron, lead, zinc, copper, and silicon.

    Silicon, iron, and lead cause hard spots and a notable decrease in gold ductility. Since these impurities isolate at the grain boundaries, it is hard to determine their presence by simple techniques. Besides, other gold impurities like Tungsten can be extremely hard to identify because they have closely similar properties and characteristics to those of gold. It may be very difficult for gold dealers to distinguish pure gold from impure gold.

    Measuring low levels of impurities in ‘bulk’ methods can give misleading purity results. It is only by using professional gold purity testing machines like the XRF analyzer that the final product’s purity can be assured. Professional analyzers are fundamentally changing the way people do business in the world of precious metals by giving fast, simple, and accurate analysis of gold metal content.
