Metallographic Analysis And Smelting Identification
The metallographic analysis technique applies the concept of metallography to detect fake gold and usually involves optical microscopy or scanning electron microscopy. Smelting consists of melting the piece of gold to be tested. Fake gold will only produce other metals like zinc and copper after the melting process.
What Type Of Karat Is My Gold
Each piece of jewelry is stamped with the karat designation somewhere on the piece. For jewelry pieces, you probably will need a magnifying glass to find a two-digit number with a k or kt after it. If you dont see a two-digit number but a three-digit number instead, place a decimal point in front of the numbers and youll have the percentage.
- .999 = 24k
- .585, .583, or .575 = 14k
- .417 = 10k
If neither of these options is available to you, Bellatory recommends other tests that you can do to determine the purity of gold.
How Can You Tell 24k Gold
To convert karats into the per centage, you need to divide the karat number by 24 and multiply the result by 100. So, for example, to find out the gold per centage in your 22 karat ring, divide 22 by 24, the result is 0.9166, multiply it with 100, so it equals to 91.66 per cent thats the purity of your gold.

Gold Purity Terminology: What Is Gold Fineness
The measure of gold purity, or fineness, refers to the gold-to-metal additive ratio. Lets look at a few terms that you may come across when studying about or shopping for gold:
- Assay: A test that determines metal content and quality
- Bullion: Precious metals in a bulk, uncoined form such as gold bars, considered in mass rather than value
- Carat: Not to be confused with Karat in North America, a Carat is a unit of weight used for precious stones. One carat is equal to 200 milligrams. Outside of North America, Carat is used in the same context as Karat.
- Ductile/Ductility: How capable a metal is of being deformed using tensile force
- Hallmark: A symbol or mark stamped on a piece of precious metal that certifies its standard of purity
- Karat: Unit of measurement for the fineness of gold, with the higher numbers containing more gold and 24K being the finest
- Malleability: How capable a metal is of being deformed using compressive force.
- Millesimal Fineness: A system used to show the purity of precious metals by parts per thousand rather than karats
- Troy Ounce: 31.1034768 grams, or approximately 1.09714 standard avoirdupois ounces
- Troy Weight: A system of measurement used for gemstones and precious metals, where a full Troy pound consists of 12 troy ounces rather than the 16 avoirdupois ounces in a standard pound
Whats The Difference Between 22k And 24k Gold
First, we need to define what the K is in these terms. The term karat refers to the fineness of gold, while the term carat refers to the weight of gemstones. So 24-karat gold jewelry tells you what the purity rating is, while 24-carat gold jewelry simply tells you how heavy it is . When shopping for jewelry, karat is nearly always the implied meaning.
Karat is symbolized as K or Kt and will be preceded by a purity rating of 10, 12, 14, 18, 22 or 24. In most advanced countries, jewelers are required by law to stamp their gold jewelry with its karat rating.
So what is 24 carat gold? Simply put, the higher the karat, the purer the gold. 24K signifies 99.9 percent purity, the highest you can buy. 24K gold is bright yellow, and its beauty and shine are unmistakable. Gold jewelry stamped 22K is approximately 91 percent pure gold, with the other 9 percent usually consisting of copper, silver or other metals.

Buy anything less than 14K and the line between fine jewelry and costume jewelry becomes blurry. In fact, most fine jewelers dont even carry 12K or 10K.

Measuring Gold Purity Using Karats
Understanding how to calculate the gold content of your product is essential when shopping for gold products. You can achieve this by knowing the number of karats in your piece of gold.
The following conversion chart will make it easy for you to calculate the purity of your gold.
|Number of Karats
We observed earlier that karats are the ratio of gold to other metals or alloys in your gold product. On the other hand, millesimal fineness is the percentage of gold expressed in parts per thousand.
Its also worth noting that a higher karat doesnt necessarily mean you have a better quality gold. It only means that you have a more pure, more expensive gold. Keep in mind that the less pure the precious metal is, the more alloys it contains.
The higher the number of alloy metals, the stronger the gold. Jewelry manufacturers prefer this type of gold to 24-karat gold. Pure gold is highly soft and vulnerable to damage.
However, a higher karat gold resists tarnishing much better than lower karat gold. Whats more, a higher carat gold has more value than its lower karat counterpart. By keeping these points in mind, youll have an easier time choosing the purity level that best suits your needs.

What Are The Differences Between Colors Of Gold
While we sometimes assume that gold is only yellow in color, we know thats not the case. Gold comes in three colors: yellow gold, white gold, and rose gold. The only difference, aside from the look, among these colors of gold is the metal and alloys mixed with the gold.
Yellow gold is said to look appealing on anyone, but especially those with olive or darker skin tones. Being the purest, yellow gold is easy for jewelers to manipulate. This type of gold can also be easily resized in the future.
White gold is less susceptible to scratching and denting, but it requires polishing and has the potential need to be dipped every few years to retain its luster and color. According to some sources such as the Diamond Pro, white gold best complements any diamonds near it.
Rose gold has become more popular over the last few years due to its unique and romantic look. Rose gold is actually the most durable among the three colors, since this type of gold is mixed with copper. However, copper can sometimes cause an allergic reaction on the skin. Because it is mixed with copper, rose gold is not available in 24k. Youll have better luck finding rose gold in 10k, 14k, or 18k.

Fact: there are really only two truly accurate ways that businesses can verify the fineness of gold they purchase. The first, naturally, is to melt it down and assay the metal. This is a somewhat costly process yielding a highly accurate result. The “fire assay” as it is known in the industry is considered the most reliable method for accurately determining the content of gold in a “lot.” It also works for silver and platinum-group metals . The second is to use an X-ray fluorescence device that can also be used on the unmeleted product. In this case it only measures the outermost portion of the metal, but it does so relativly precisely. This machine has become a key component of most gold processing facilities . The beauty of the XRF machine is that the concentration of gold can be determined somewhat near to a fire assay. Yet, it only takes a fraction of the time .

Why Should You Buy Gold
Gold is considered to be one of the safer investments because it seems to withstand economic lows, recover quickly, and retain its value better than other assets. Buying gold and investing in gold purchases is different than investing in stocks and bonds since gold gives you something that you can physically own. However, you can purchase stocks and bonds in gold mining companies if youd prefer to go a less traditional route.
Additionally, gold has been a great defender against inflation. During years of high inflation, stock markets took a dive while the value of gold increased. During times of deflation, having gold was considered a positive for people who may not turn to banks, investments, and stocks. One way to protect your assets is to have your assets be in a tangible form, such as gold. You can also keep your gold assets private. Even though you must still report any gain on your yearly taxes, gold is one of the only assets that can be anonymous.
Further, buying and investing in gold is not something that you need significant amount of educational experience to be able to do. Professionals can provide you with a great deal of information and can help answer any questions that you may have.
