## The Gold Karatage System

How to Test Gold Using Specific Gravity.

Most gold jewelry uses the Karatage system to define the gold content in the piece. It is used to to identify the fineness or purity of gold as a fraction of 24 parts. Pure gold is 24 karats which has a fineness of .9999 or 99.99%. Sometimes gold content is expressed in parts per thousand so if you see 500 stamped on your gold jewelry, it is an alloy containing 50% gold.

You can use the following Karatage list as a guide to for determining gold fineness and percentages in the U.S.

Let’s say you have a piece of gold jewelry you are interested in selling. You see a 18K stamp on the jewelry so you know it is 75% pure gold. Since gold is such a soft metal, the remaining 25% is likely one or more metals to “harden” the piece of jewelry, add color to it or both.

Most dealers will quote you a price for your gold by gram or pennyweight, taking into account the gold fineness. So, in the example above, they will give you a price of what they are paying for an 18K piece of jewelry based on the weight and a gold fineness of .7500 or 75% purity.

The question then becomes “Is that a fair deal? What percent discount is their offer in relation to the spot price of gold?” That is the subject of a another article -Selling Your Scrap Gold.

## What If I Want A Professional To Examine My Gold

All of these tests can be performed at home some with more caution than others. However, none of these methods are infallible. The best way to tell if gold is real or not is to have a reputable jewelry buyer take a look at it. This way, youre able to get an honest assessment of your jewelry or watch from a competent gold buyer.

Most jewelry stores charge a small fee to test if your gold is real, but Leo Hamels offers this service for free.

## Measuring Gold Purity Via Density Determination

Pure gold is a relatively dense material with a density of 19.34 g/mL when measured at 20°C. To confirm the purity of an item of gold or a piece of gold jewelry, the density can be measured and the results compared to the density of pure gold.

The density of the item is determined by first weighing the item in air and then again submerged in water. This can be achieved using a dedicated density kit installed on a jewelry scale or gold scale. Alternatively, the item can be weighed first in air by suspending it below the scale and then a water bath is raised up to cover the item .

The results of determining density by this process are dependent upon the ambient temperature. This must be adjusted for in the density calculation.

Measuring gold purity via density determination provides a quick, first indication of the purity. Further investigations, such as using x-rays, may be required to determine if the jewelry has a fake core. For example, the density of tungsten is comparable to that of gold and can be hidden under the gold alloy.

## Industrial And Commercial Uses

About half of the gold and silver produced in the world is used in jewelry. When there is a high demand for jewelry, the supply of these metals becomes limited, which automatically raises their price. The opposite is true when there is a lower demand for gold and silver.

Gold on its own has also been found to contain amazing electrical and thermal conductivity properties and this makes it an important metal in various industries. In addition, owing to its resistance to bacteria colonization, gold is one of the most commonly used metals in the medical field.

If there is an increased demand for gold and silver due to an upsurge in the production of jewelry or any commercial usage, the price of the metals will also go up and so is that of Olympic gold medals.

When all is said and done, the price of gold and silver will primarily depend on the demand and supply of the metals in the market. Ideally, when there is enough supply of these metals, producing Olympic gold medals will be less costly and vise versa.

## Avoid Large Gold Bars

10-ounce and 50 grams gold bars are among the easiest to tamper with as they can be drilled, filled with tungsten, and then plugged again with gold. This is more difficult with units 1 oz and smaller. Tungsten is extraordinarily hard whereas gold is soft. This means tungsten is very difficult to use in minting or fabricating small items. It is brittle, and stamping it with a design will result in coins with less detail unless it has been plated with a thick layer of gold.

## How To Accurately Weigh Your Scrap Gold

We often speak to customers who dont have any scales on which to accurately weigh their scrap gold.

Heres a tip weve been giving to customers for some time

Weigh your gold at your post office. Post office scales are trade approved and are therefore very accurate. Obviously, you dont want others to see what youre doing, so put your jewellery into a plain envelope and seal it. Make sure you have an identical empty envelope with you. Weigh the empty envelope and note its weight, then weigh the envelope with your gold in it. Subtract the weight of the empty envelope and voila! You have the weight of your gold.

Finally, a note about digital kitchen scales. Please bear in mind they probably arent as accurate as you think. Many only weigh in increments of 5 grams and its very common for kitchen scales to be out by several grams. If in doubt, use the above tip.

## Different Olympic Games And The Estimated Cost Of Each Gold Medal

## Measuring The Weight Of Gold

To measure the weight of gold accurately, follow these steps:

• First, calibrate your scale by testing the scale using an object whose weight is known. Make sure that you are using a gram weighing scale, and if you want to ensure the best level of accuracy, you might want to buy the gram weight along with the scale. To ensure accuracy of the weight readings, calibrate the scale only after placing the scale on a hard, level surface. Only when the scale is leveled out can you calibrate it. Keep in mind that the readings on the scale must be exactly like the test weight.
• Now that you have calibrated the scale place the gold piece to be weighed on the scale, then read out the result. Note that you should weigh the gold items individually unless you know the actual purity level of each piece. But to ensure the best and the highest level of accuracy, you should think of weighing each of the gold pieces separately.
• To avoid confusion, list every piece to be weighed and indicate their exact weight against each piece, along with the gold content or the karatage. You need this information to calculate the value of the gold.
• ## How To Measure The Weight Of Gold

The value of gold cannot be determined without knowing its purity and weight. Gold’s purity is valued in carats and its weight is measured in grams or Troy Ounces. Unless it’s scrap gold that is being weighed, the gold content will probably be stamped on the item, certifying it to a certain standard of purity such as 12 carats which is 50% pure or 99.99% fine, which is equivalent to 24 carats, 100% pure gold. Digital gram scales and chemical gold content testing kits can be purchased on the internet for under \$30.

## First: How Many Karats Is It

First things first, youll want to know what karatage you are working with. Gold jewelry pieces have hallmarks, or stamps, which notate karatage or gold purity. If you need to, grab a magnifying glass and examine the jewelry. Do you see any numbers or lettering? If not, keep looking. The karatage of the ring will be a number followed by k or kt for example 10K, or 14Kt.

Did you find it? Great! If not, you may find a larger number which represents the gold purity of the ring. Gold purity hallmark examples include 585, 417 and 750. What do these numbers mean? Essentially, gold purity numbers are percentages, and to convert them to decimals you simply add a decimal one digit from the right.

This means that 585 becomes 58.5%, which is the amount of pure gold in the jewelry piece. The higher the number/percentage, the more pure gold in the jewelry, the greater value.

Confused? No problem! Read our guide for detailed information on identifying gold jewelry stamps.

In some cases, you may not find a stamp and there are several reasons why:

• The stamp rubbed off
• The stamp is illegible
• The jewelry item has been resized or altered, and the stamp was removed in the process.
• The gold jewelry is not real gold
• If youre unsure about whether your gold jewelry is real, here are some tips for how to test gold jewelry at home. If youre positive the gold is real gold, then its smart to take it to a jeweler to determine the exact caratage.

## So How Can I Test Gold At Home

Now that you know golds properties, the following tests will help you determine if your gold is real, and what is its true purity. Below are the most common ways to test gold, and you should always do more than one to test your gold. These include simple procedures from how to test gold at home to using gold testing machines for getting the most accurate results. First, we will start with DIY gold testing.

## Calculating The Gold Content Value Of A Jewelry Piece

In summary, to determine the gold value content of an item, you first need three bits of information.

• Weight

Next, if you encounter weights measured in pennyweights, grains, and grams, remember these conversions.

• 20 dwt to a troy ounce
• 480 gr to a troy ounce
• 31 gm, approximately, to a troy ounce

Divide the daily gold price per troy ounce by the appropriate number above. Then, multiply that result by the weight of the item to calculate its pure gold price.

Finally, multiply the items pure gold price by its gold content percentage . This final result indicates the value of the actual gold content of the item. Now, you can figure out the jewelers markup for the piece.

## Converting Gold Karats To A Percentage

Once you know the karats of your gold jewelry, its best to convert them to a percentage in order to figure out what part of the gold alloy you have is actually pure gold.

This calculation is straightforward: Just divide the karat number of your jewelry by 24 and multiply by 100.

For example, if you have determined that a gold item is 18 karats, dividing 18 by 24 gives you 0.75, which is equal to 75% gold content.

## Legal For Trade Gold Weighing Scales

In many countries, where a product is sold by weight, the scale or balance used must be a ‘Legal for Trade ‘ version . The regulations vary from country to country, and retailers must ensure they meet local requirements. Legal for Trade scales and balances undergo more rigorous testing than a standard scale or balance. Only scales and balances that successfully pass the tests can be declared as Legal for Trade. Such scales and balances are sealed at the manufacturer’s site to prevent the scale from being opened by unauthorized personnel.
