Real gold jewelry, white gold, rose gold, and other gold products like gold bars, bullion coins, and other gold pieces are beautiful and a good investment. But how do you test gold for gold authenticity?

Pawn shops like R&J Jewelry and Loan buy, sell, and loan against precious gold. They have experts who can test gold and determine if it is real or fake gold, fool gold, gas station gold, gold plated, or another metal.

The pawn brokers are experts in filtering out fake gold pieces from the real deal. before the pawn shop considers buying or loaning against any precious metal, they test the pieces. This protects the consumer and the shop.

Fools Gold

What is Fools Gold?

Fools, gold is not gold. It is the mineral pyrite. The mineral resembles gold, which is why it gained the name fools gold. You can test the gold if you are concerned that the gold you have is not authentic gold.

Counterfeit or Fake Gold

Counterfeit gold, silver, gold bars, bullion, designer handbags, and luxury watches like Rolex are everywhere. Advancements in technology has helped fine-tune the steps counterfeiters go through to create fraudulent products.

To decrease the risk of purchasing a fraudulent product, there are some things you can do to test gold to make sure it isn’t imitation gold or something fake.

Gold Reviews

First, Do Your Research!

Make sure you are working with a reputable company. You can check the company’s Google Reviews, standing with the Better Business Bureau and other related social media sites. Read what people say. With Google Reviews, the ability to search businesses on the Better Business Bureau or other regulating sites, and social media. It is fairly easy and common to check the reputation of the dealer you decide to purchase your gold bars from. Take the time to research local pawn shops, read the reviews, and ask around.

Gold Purity

Second, Do A Visual Test – All That Glitters Could Be Something Other Than Gold

Take some time to look at the gold you are considering. There are some things that you will notice that is unique to genuine gold.

Color: Pure gold is yellow to golden in color. If the gold is white-gold, it is ordinarily a combination of 75% gold and 25% nickel and zinc. Rose gold has a rosy appears because of the gold being mixed with copper alloys.

Pure gold is 99.9% gold and marked 24k, 18k is 75% gold and 25% other metals like silver and copper. 14k gold is 58.3% gold, and 41.7% alloy metals. 10k gold is made up of 41.7% gold, and 58.3% alloy metals. Because of the alloys used, 10k gold is a pale yellow color.


Gold does not tarnish. The metal is bright. 24k gold being the purist will be soft and easy to bend.


Gold is typically found in particles with slightly rounded edges.


Third, Weight of Gold – Real Gold Won’t Pass the Float Test

Real gold is dense and heavy. Gold is weighed in troy ounces (31.1 grams). Did you know that if you drop a fake gold bar in water, it will float? Genuine gold will sink straight to the bottom. So if the gold item floats, it’s fake.


Fourth, Bendability

Gold in its purist form, 24k, is pliable. This is why most jewelry is made from gold that is not 24k, because gold has an incredible ductility, which means it bends and dents easily under pressure.

Fifth, Magnet Test

Get a strong rare earth magnet, which you can purchase from a hardware store. Touch the gold you are considering buying to the magnet. The magnet won’t hurt the gold. If the gold piece sticks, you are likely to have counterfeit gold. Pure gold is not magnetic.

Sixth, If the Price Is Too Good, Tread Cautiously

Gold sells according to the current “spot price”. The spot price is the market price of gold, and it is based on supply and demand, and thus ebbs and flows with the current economic conditions. World events, consumer spending, interest rates all affect the economy.

You can look up the spot price of gold or any precious metal. If the spot price is high, ask yourself if the huge discount you were offered because the gold piece you were considering isn’t real? It’s okay to question is the deal too good to be true?

Sometimes people or companies selling fake gold jewelry, gold plated jewelry as real gold, gold filled products as real gold, or other gold counterfeits will try to hook you with a deal. Most valuable metals come with a fair spot price, not cheap.

Seventh, Self Test Gold with Liquid Foundation – The Skin Test

Did you know you can use some liquid foundation makeup and rub the gold against it on your skin? If it leaves a black streak, it is likely gold. Find a friend with anemia or low iron. The same will happen, because the gold reacts to the blood’s hemoglobin. 


Eighth, Test Gold At Home with A Few Drops of Nitric Acid

You could test a gold piece of jewelry with nitric acid. Make a small scratch, so that the scratch penetrates the top layer of the gold. When you place a small drop of nitric acid on the scratch, see if the mark turns green or milky. If there is no reaction, the gold piece is probably real gold.

Unfortunately, nitric acid is a dangerous chemical, so you will need gloves, goggles and a well ventilated area to test gold.

Nineth, Look at the Plastic Wrapping or Packaging If You Are Buying Gold Bars

If you consider buying gold bars or gold bullion, they will come in a plastic wrapper. Fake gold bars come in thicker plastic because they hide the bar’s weight. It also distorts the details on the bar’s surface, so you may not notice imperfections or missing details.

Nearly every gold bar or piece of jewelry comes with a hallmark. The hallmark tells what karat weight the piece is and if it is 24k, 14k, 10k, or karats in between, like 18k. The mark can be manufactured so it “appears” you may notice some flaws.

Some gold bars have a layer of gold, and then they are filled with tungsten or another alloy, making them feel heavy and real.

Troy Ounce - Gold

Tenth, Stamp Test

Gold bars are fraudulently stamped with the logos of major refineries. The fakes are often difficult to spot, and because of this, fake gold bars are ideal fund runners. There are several million bars stamped with refinery logos that weren’t actually produced by those facilities, reported JPMorgan Chase & Co. The fake bars are highly professionally done.

When you look at the marking, use a magnifying glass to validate the purity of the numbers and stamps. Look for the hallmark and letter mark. Sometimes the marks are hidden under a clasp or in another inconspicuous place on the gold piece. The hallmark is the international standard, which defines the purity of valuable metals. Remember, it is not beyond fraudulent brokers to engrave these themselves, making gold plated jewelry appear like real gold.

Eleventh, The Ceramic Scratch Test

You can take a piece of unglazed ceramic tile or plate and lay the tile on a flat surface. Scrape a piece of gold across it, and real gold will leave a gold mark or trail. Other metals will leave a black trail.

Genuine Gold Facts:

Gold Purity and the Karat System

Gold has different purity. All gold spot prices are based on gold being 99.9% pure.

24k gold is considered “pure” gold without traces of other metals. 24k gold is soft and bright yellow. It is mainly used in gold bars, bullion, and coins.

18k gold is 75% pure, 14k is 58.3% pure, and 10k is 41.7 pure.

The weight of gold is measured in troy ounces; however, its purity is measured in ‘carats.’ Since the spot price of gold is based on gold being 99.9% pure, the more other metals are in the gold, the less refined, the less it’s worth.

Shop Wisely – eBay, Marketplace, and Other Online Requests

These forums may increase the risk that the gold bars, bullion, and rounds you want to buy for good money may be fraudulent. Make sure the price matches what you are buying. There may be a concern about cheap gold and a huge discount.

Pawn Shop

As a shopper of gold, it may be the best place to shop. If you are a seller, they are happy to work with you to get you a fair market value offer. If you create a relationship with the pawnbrokers, read the feedback from other shoppers, and visit the store often, you will learn quickly that the company’s delivery on their promises is 100%.

Audemars Piguet Watches

North of Geneva, in the Jura Mountains, in the small town of The Vallee de Joux, the Audemars Piguet watch brand was born. Due to the iron ore available in the region, the Swiss timepiece evolved into the brand it is today.

In the 18 century, during the winter months, farmers would spend hours a day in their homes’ day light-filled rooms crafting wheels, bridges, semi-precious stones, pinions, and springs for the watchmaking industry. The tight-knit community and the family artists led the way for the brand name Audemars Piguet watches.

Louis Audemars and Edward Auguste Piguet were childhood friends and reconnected in the 1870s. They discovered they were both watchmakers and were working to create mechanical timepieces. 

By 1875 the two men joined together to create the brand that we know today as Audemars Piguet.

Before they joined forces, Audemars created complicated watch movements for different manufacturers to then finish and fit into their own cases.

Piguet performed the final regulation on the watches.

After they started working together, Audemars oversaw the watches’ production and technical aspects, and Piguet focused his time on sales and management.

By 1881 the watchmaking team announced the name Audemars Piguet & Cie, a watch brand known today.

Audemars and Piguet died in 1918 and 1919, respectively. The company continued with sons Paul Louis Audemars and Paul Edward Piguet, moving the company forward to the success seen today.

During the early-mid 1900s, the two sons pushed for innovation and, in 1925, released the thinnest pocket watch caliber. The first skeletonized pocket watch was released in 1934.

Grand Complication Pocket Watch was released in 1899. It featured a minute repeater, alarm, perpetual calendar, deadbeat seconds, chronograph, and split-seconds hand.

The company built a reputation for inventiveness when it unveiled the first-minute repeater wristwatch in 1892. They continued with their ingenuity by pioneering the jumping seconds hand pocket watch. and the first skeleton watch.



Skeleton Pocket Watch

A skeleton pocket watch is a pocket watch that shows the inner movement that makes the watch “tick.” The mechanisms are seen through glass or uncovered directly so you can touch the mechanisms oh so gently. The word skeleton watch was used because the outer case is like the “skin” on the body and the inside or underneath is the skeleton.

In 1946, Audemars Piguet launched the world’s thinnest wristwatch. In 1967 the brand released the first self-winding automatic caliber featuring a central rotor with a thickness of 2.45mm.

On the eve of the 1972 Swiss Watch Show, Audemars Piguet gave Genta the task of creating a luxury sports watch. The next day Genta presented the idea of the Royal Oak.

Royal Oak Audemars Piguet

The Royal Oak

The Royal Oak featured was made of stainless steel and an integrated bracelet. This was different than other previously made Audemars Piguet watches. The case of the Royal Oak had daring designs not ordinarily seen on other watch brands. The octagon bezel with eight screws featured a round dial. The design is iconic and is still sought after today.

The watch saved the Audemars Piguet watch company brand by making it one of the most popular models in the watch industry. In 1972 when it was first produced, it took three years for Audemars Piguet to sell 1,000 Royal Oaks since sales have increased.

The Royal Oak Blue Dial men’s watch was launched at the Basel fair in 1972. Never seen before, the luxury watch is a steel timepiece and more expensive than the Patek Philippe dress watch and more than ten times the cost of a Rolex Submariner.

The Royal Oak Offshore in 18k gold with a black ceramic bezel, push-pieces, and screw-locked crown was introduced in 1993. It is one of the most prominent sports watches of all time. It is a fusion of rose gold and a black ceramic case.

Some Royal Oak watches feature the Royal Oak Hands with luminescent coating making this watch one for collectors.

Audemars Piguet introduced black ceramic into the Royal Oak Line in 2017. The black ceramic is made of zirconium oxide and yttrium oxide. The black ceramic is seen in some Offshore models. The Royal Oak Line also comes in various metals and finishes, from steel to 18k gold to frosted gold and pave diamond designs.

The Royal Oak Offshore is known for its bold look and more masculine and sportier presentation, which is different than the classic Royal Oak.

The Royal Oak celebrates its 5oth anniversary this year. It is one of the most collectible watches available. Audemars Piguet released the 39-mm Royal Oak Selfwinding Flying Tourbillion Extra-Thin to mark the momentous occasion.

There is no denying that the Royal Oak inspired other brands and models.

The Royal Oak Concept Flying Tourbillion GMT

The Audemars Piguet Royal Oak Concept Flying Tourbillon GMT is part of the line and case that has been used for eighteen years. The first Royal Oak Concept watch, designed by Claude Emmenegger, was presented in 2002 to mark the 30th anniversary of the Royal Oak.

The movement was developed by Audemars Piguet Renaud & Papi (APR&P). The line tends to be more experimental than the Royal Oak Offshore. The line has been a springboard for technical development. The first version combined a titanium case, a black ceramic bezel, a blacked-out dial/movement, and featured rose-gold accents. The watch was flashy and sophisticated looking.

The subsequent model was the Royal Oak GMT Tourbillion and was more low-key. It is monochromatic gray, including the display, the rubber strap and clasp, and even the movement’s back. The large case is made from sandblasted titanium. The bezel is complimentary and also sandblasted titanium. The screw-down crown and the push-piece at the side of the case are grey ceramic.

The Jules Audemars Collection

As a tribute to the original founders, Jules Louis Audemars, the collection has a simple, classic, and sometimes vintage appeal. Jules Audemars was a pioneer in the watch industry. He was dedicated to the art of mechanical calibers and was refined and artful. The collection features Audemars Piguet watches.

Audemars Piguet Jules Audemars Perpetual Calendar

Audemars Piguet watches are often considered in terms of the Royal Oak and Royal Oak Offshore watches. A finer, less sporty watch is the Jules Audemars Perpetual Calendar.

Not known as an everyday watch, it is a special kind of watch that is worn on special occasions. The watch has a brown sunray dial, with rose gold index hour markers and hands.

A finely printed seconds and minutes track appears between the applied rose gold index hour markers around the dial’s perimeter.

Turn the watch over, and the watch features a transparent sapphire back that is secured with six screws evenly spaced, with three on top and three on the bottom. The back reveals the in-house caliber.

The case itself is 18kt rose gold and slender in appearance. It has a polished fixed bezel and lugs with a brushed finish. The movement is an ornately engraved and partially skeletonized solid gold automatic winding rotor. The letters AP show along with the different features of the movement such as “ADJ TO HEAT COLD FIVE (5) POSITIONS”,  “ISOCHRONISM,” and “THIRTY-EIGHT (38) JEWELS”, “SWISS AUTOMATIC,” along with the AP logo.

The Calendar sub-registers are a slightly darker brown and have a white printed typeface to indicate the day, date day of the week, and leap year indicator located at the center of the 12 o’clock sub-dial. The moon phase is displayed in vivid color at the 6 o’clock position.
