how to identify gold: 13 ways tell you if gold is real and

The business of selling, purchasing and processing of gold into jewelries and other materials has grown into a very profitable industry. China (14%), Russia (9%) and Australia (8%) are the top three producers of raw gold bullion which is the raw material for producing jewelry

These three countries and others have a total world production value of $119billion. This value was in 2014 according to bullionvault and has definitely increased in recent years. Unfortunately, the profitability of this business has also attracted the attention of dishonest people. These criminally minded individuals have learnt to combine various inexpensive metals and coat them to have the appearance and shape of pure gold.Many people have unwittingly become victims of these criminals, losing vast sums of money as payments for “original gold jewelry products”. The advent of technology has made it seemingly easier for these forgers to carry out their trade. Despite all of this, there are still some subtle methods by which fake gold can be identified. This article will give you basic tips and pointers to quickly identify fake gold and differentiate it from the real thing

In identifying fake gold, an important starting point is to gain knowledge about the different types of gold jewelries. To the untrained eye, all gold products are the same and differ only in the color due to finishing applied. There are however more subtle differences in various gold products which we shall discuss shortly

Avoiding fake gold products may seem very difficult due to the advanced technology being used by counterfeiters. There are however ways known to experts about how to identify fake gold and stay away from it. These include basic methods such as:

The proliferation of fake gold is a serious threat to the success of all stake holders in the gold and jewelry industry. As formidable as the problem seems, there are still ways to circumvent the efforts of gold fakers and forgers

how to identify raw gold | sciencing

Fool's gold can be mistaken for placer gold – gold found as rounded or flat nuggets in dry and wet stream beds, and rivers or creeks – because they both look golden. But real gold stays bright even when out of direct sunlight, and though soft, does not fall apart when you touch it like fool's gold can. Raw gold in rocks appears as threads of a yellow-gold color winding its way through quartz

One of the ways to find raw gold begins with panning for it in creeks or rivers fed by eroded gold from mine or natural deposits in rock formations above the water sources. Placer gold, roughly 75-to-95 percent real gold comes in a variety of shapes and sizes, from small flakes to large bumpy nuggets. When panning, raw gold weighs the heaviest and is found in the rifles or along the bottom edge of the pan

Perform a simple test of the material in the pan to assess whether it is real gold. Raw gold appears brassy yellow and bright. If you think it is gold, place your hand between it and the sun to create shade over the gold. If it still appears bright in the pan, chances are that it is real gold. Fool's gold does not appear as bright when shaded

Raw gold has a smooth, but bumpy texture, caused as the gold tumbles through rivers and streams. When you set it in your palm, and set a rock of equal size next to it, the real gold feels substantially heavier. Flakes of fool's gold – iron pyrite – break apart easily when you thrust a fingernail through it in the gold pan. Fool's gold also has more jagged edges compared with placer gold whose edges have been smoothed by hitting rocks and debris in a river. Quartz rocks sometimes have threads of gold running through them, but this type of gold may require a professional's opinion to determine if it is really gold. To make specimen for museums from veins of gold in quartz, professionals melt the quartz in an acid bath, leaving just enough of the quartz as a base for the threadlike filigree-appearing gold

Hold the placer gold up to the light. It has a shiny surface that glistens as it is twisted in light, but it does not twinkle or sparkle. Fool's gold twinkles and sparkles in light, reflecting the light and creating a glittery effect in the pan. Real gold is bright yellow with a shiny, metallic surface

Nugget gold is a soft, malleable metal that bends easily. If you tap it lightly with a hammer, gold dents rather than breaks. Other non-gold metals or minerals can break when hammer. Strike the gold firmly to check whether or not you can dent it without it breaking. Place the substance in corrosive nitric acid, using care to avoid getting it on your skin. Nitric acid does not dissolve or tarnish raw gold. Fool's gold, however, also is not affected by nitric acid, but other identification methods will help you determine whether or not the specimen is fool's gold

gold ore - the official terraria wiki

Gold Ore is an early game ore which spawns in the Underground and Cavern layers. Its primary use is to make Gold Bars, which can be used to make the Gold tier of equipment, as well as crowns, Thrones, and several other items. The equivalent of Gold Ore is Platinum Ore, which will sometimes replace Gold in a world.     Gold Ore has a small chance to appear as a bonus drop from slimes.

Not all gold deposits out there have been found and mined. There are still places that contain gold that have never been worked, despite the fact that miners have been searching for gold for hundreds of years now. If you can find one of these undiscovered gold deposits you have a good chance that you have found something special, since you will have been the first person to mine it. To find one of these deposits, you need to be able to identify the natural indicators that will lead you to finding the gold

It is extremely important to learn about the geology of your particular mining district. All areas are different, and you need to understand what to look for in the specific area that you are searching for gold. There are certain things that are common to all gold districts, but understanding exactly where and how gold is found in the particular district that you are searching is extremely important

When researching a mining district, good gold geology references will indicate the general rock types that area associated with the productive gold mines in the area. Pay attention to these most common rock types and always be looking for them when you are out prospecting. They can be an indicator of where gold will occur

The general rock type alone is generally not a great indicator or where to search, since it is probably common once you are within a known gold district, but it is one of many things that are worth considering

Probably just as important to identifying the country rocks associated with gold is being able to identify the host rocks that are generally not associated with gold. If your research has never indicated that gold occurs within a certain rock type, then you certainly don’t want to spend a significant amount of time searching within that type of geology

Several nice gold nuggets found in an afternoon of metal detecting. This location was at least 1/4 mile from the nearest historic”diggings,” but careful study of the surrounding rock types meant that there was a good likelihood that there was more gold to be found…
