TOP 4 best ways - how to weigh gold at home without scales: how to determine the weight of jewelry in grams

Post updated: May 27, 2020

Gold is a fairly heavy metal with a high density of 19.32 g/cm3. According to this indicator, gold ranks 7th among all metals. Different systems have different units of measurement: SI = N\M3, MCSS = 1 kg\m3, SGS = 1 din\cm3. Also, the specific gravity of gold can be expressed in grams per cm3 (non-systemic unit).

Specific gravity, expressed in g/cm3, is equal to the density of a given metal. For gold, this figure is 19.3 g/cm3. The volumetric weight of gold is a calculated value that reflects the density of the metal.

Types of ingots

There are several types of ingot standards, which have different applications and technologies. According to the method of application, they are divided into the following:

• measured;
• standard.

gold bars
are intended for sale to citizens, standard ones are used only for technological needs. According to production technology, there are several types:

• stamped;
• powder;
• cast.

The designation of stamped ones is SZSh, their weight does not exceed half a kilogram, they can easily be lifted with just your fingers. When stamping, they are cut from flat sheets. Powder ingots are made using the electrolytic method, and metal powders are used for their production. They are not used in the Russian Federation. They are the cheapest and are also rarely used by banks in other countries.

Ingots that are made by casting have a large mass and will be difficult to lift with your fingers. Cast bricks weigh more than 500 grams, they are designated SLZ. The price ranges between powder and stamped. If the product does not meet the requirements of GOST, then it is sent to the manufacturer for re-melting. Most of them must comply with the requirements of the London Bullion Market Association.

TOP 4 ways to weigh gold at home without scales

There are several ways. The most accurate way is to contact a specialist. However, there are ways to weigh gold at home without special instruments:

Compare with decorating the same sample using a glass of water

Place a product whose weight is known inside a glass filled to the brim. The water displaced from the glass is its volume. Do the same with another object whose weight we need to know. Knowing the volume of two jewelry, you can compare their weight, but errors will be possible.

Let's repeat the law from physics. Method errors

For this method, you need to know the sample or density. You need to place a glass filled to the brim with water inside the pan and immerse the valuable item. Water equal to its volume will flow out. It is easy to measure the volume using an insulin syringe. Using a simple formula, we obtain the desired value.

The method has an error, since the density cannot always be known accurately, and not all of the water can be collected.

"Libra" of Asian traders

Soviet store scales worked on this principle: 2 plates and weights. Instead of weights, it is convenient to use coins, the weight of which can be found on the Internet. You need to take a hard stick, thread, 2 identical small containers and coins.

Reviews:

I wanted to know how expensive the ring the young man gave me was. I took your advice and was pleasantly surprised. I weighed it using a ruler. I remembered my physics lessons, very interesting. I didn’t even know it was possible to spot a fake so easily.

When I needed money to buy myself a new iPhone, I decided to take my jewelry to a pawnshop. I decided to play it safe and find out the weight. I was afraid that they would deceive me and pay less. Buying special scales is not profitable, but these tips came in handy. I checked it in different ways for accuracy and went to take it. You can't fool me!) I bought the phone.

Excellent advice, some of them were taught by my father in childhood. He is an archaeologist and knows everything about precious metals.

Acquisition and sale

It's good to know where you can buy gold bars. After all, this is a specific material; you cannot buy it in the nearest store. It is necessary to have at least a basic understanding of domestic and world standards. You need to understand how much gold there is in the bar.

The most reliable option is to come to a banking institution and purchase value. You can use the service of impersonal metal accounts. Another alternative is to purchase it secondhand or on the exchange through a brokerage company. We should not forget about jewelry stores, although they, as a rule, do not specialize in simple bullion trading.

As you can see, there are quite a lot of options. But you must be careful and have a clear head so as not to purchase a fake. Although this option is unlikely, stories about similar problems pop up here and there from time to time.

Now, how is bank gold sold? Places of sale are the same as when purchasing. Although the process has its own specifics. For example, in some cases it is possible to sell not the bullion itself, but securities that correspond to its equivalent. In this case, the gold itself will be in the safe deposit box. When selling ingots, an examination is usually requested. This negatively affects the amount of profit received. Those who want to make money in the short term using bank gold usually use impersonal metal accounts.

How much does a gram of 999 gold cost?

Pure gold is the hardest currency in the world: it is the main reserve of states. The cost of a gram of 999 gold is constantly increasing, albeit sometimes only slightly. Price fluctuations depend on macroeconomics and international politics. For example, there is a pronounced tendency to depend on the US national currency: the higher the dollar exchange rate, the cheaper gold, and vice versa.

The most important role in pricing is played by the amount of gold mined. The second point is the alliance of supply and demand. The more precious metal buyers need, the more expensive it costs.

Until 1971, it was gold that acted as a regulator of the value of currencies: the exchange rate was tied to it. Now the national currency is backed by GDP: it now serves as a measure of the strength of the economy.

The price of 1 gram of 999 gold today on the international market is set on the London stock exchange, and it changes several times a day. The main regulator of internal pricing within the Russian Federation is the Central Bank: it accounts for about 60% of the total turnover of precious metals.

The weight of a gold bar determines its value, and the buying and selling rates sometimes differ significantly. For example, at the time of writing this article, the cost of 1 gram of pure gold was 4,384/4,718 rubles (purchase/sale at Sberbank).

Nobody knows how much gold will cost tomorrow, the day after tomorrow or in a week, otherwise it would be possible to get rich with a wave of your hand, only from the difference in quotes. Gold may fall slightly in price, but the upward trend in value relative to the domestic ruble has persisted for several decades.

Dependence of the weight of a gold product on its purity. Percentage calculation

Objects of the same volume can have different weights, since it also depends on density. Each sample of gold has a certain density and, accordingly, its specific gravity. Table with the density of different samples:

Gold nuggets
The sample is placed next to the stamp in accordance with GOST, compliance with which is controlled by the Assay Office. The numbers indicate the gold content: 750 sample contains 75% of the base metal, and 585 - 58.5%. Jewelers do not disclose the percentage of ligatures.

Introductory information

The noble metal is present on earth in limited quantities. If it runs out, its value will increase over the years. Although it is possible to learn how to synthesize it. But now we have to make do with what we have. Bank gold is bullion with a purity of 999(.9). What does this indicator mean? If gold is 999, then this means that the bar contains 999 parts of the precious metal and 1 unit of impurities out of 1000. For 999.9 the quality is even better. The amount of impurities in it is reduced by 10 times. But obtaining such pure precious metal is very problematic and expensive. The purity of bank gold affects the price, as does the weight.

Where is 999 gold standard used?

As mentioned above, pure gold is used extremely rarely for the manufacture of jewelry and luxury items for utilitarian purposes. This metal is too soft: it is prone to deformation, quickly becomes scratched and loses its shine.

On the left is a ring made of 999-karat gold, on the right is a ring made of 585-karat gold (from the Golden Radiance Sunlight collection).
Sometimes massive jewelry is made from gold of the highest standard on special order (mainly wedding rings), but they do not differ in high performance characteristics. This is jewelry that is worn exclusively for presentation purposes, when going out.

Most often, pure gold is used:

• For the manufacture of jewelry alloyed with other metals. By adding alloys, gold acquires the required strength and desired color. The more ligatures, the lower the sample.
• In the production of electronics. Gold has the highest electrical conductivity and resistance to oxidation, which makes it indispensable in the production of semiconductors and microcircuits.
• As a decorative covering. Since ancient times, church domes have been covered with the finest foil made of this noble metal (gold leaf). Now it is also used to decorate luxury items, icons and religious utensils.
• In cooking. Yes, yes, dishes decorated with “edible” gold can be tasted in many elite restaurants.
• For the production of measured bars and collectible coins. They are sold in special bags and capsules, accompanied by certificates certifying their “official” origin and recorded weight.

In bank branches you can buy both small bars weighing 1,5,10 and 20 grams, as well as more massive ones - 0.5 and even 1 kg of pure gold. The first ones are 20-30% more expensive, but they are easier to sell later. The ideal option is bars weighing 50 and 100 grams.

How much does it cost?

You can't say it that quickly. This is due to the fact that the answer to this question depends on a number of factors that can significantly affect the price. Bank gold varies within a certain range depending on:

1. Added value. This includes the costs that were incurred when producing the ingot at the refinery, its transportation to the bank, insurance deductions, and a percentage of profit.
2. The cost of pure gold. It is set daily during trading that takes place on the largest precious metals exchanges.
3. Refining. In simple terms, this is payment for the manufacturer's brand. That is, ingots cast or stamped by well-known manufacturers will cost more than those created by less popular ones.
4. Presence/absence of a certificate of conformity provided by the manufacturer.
5. Production technologies. Stamped ingots are always more expensive than cast ones.
6. Packaging forms. If it is not there, then the ingots will be cheaper. Then comes the standard one, followed by the hardened (gift) type.

How to determine the weight of a gold ring if there are no scales?

Expert opinion

Grishanov Mikhail Petrovich

Jeweler, director of the Grishanov and Co. workshop

You can determine it in different ways, one of them is to go to a jeweler. However, there are 4 ways to help determine the weight of jewelry yourself: compare it with another product of the same standard, using a glass of water, use the experience of Asian traders, or a homemade device using a spacer and a ruler.

Description of the noble metal. How can you determine its purity?

Gold is an element of group 11 with atomic number 79 of the periodic table. This metal was the first to be discovered by man due to its unusual attractive color. Jewelry from it began to be created in Ancient Egypt, India, and China. Solar metal is mentioned in ancient myths, the Bible, and sacred scriptures. This material is very plastic; from 1 gram you can stretch a wire up to 2 km long.

Now the precious metal is used to create dishes, clothing, furniture, jewelry, and interior items; it is a product for investment and savings. Pure gold without impurities does not exist in nature.

After extraction, it is purified, but 0.01% of other components still remain.

Gold, native
To assess the purity of the composition, world measurement systems were introduced: metric, carat. The first expresses the ratio of grams of pure metal per kilogram of product. The karat system reflects the number of parts of gold per 24 parts of the alloy. Relationship between world systems:

Basic physical and mechanical properties of gold

In addition to specific gravity, the physical and mechanical properties of gold are also important characteristics.

Color. According to this indicator, of all the metals, only gold (yellow) and copper (pinkish-red) have their own special, characteristic color. As for other metals, it is more complicated - for example, white color is characteristic of platinum, silver, aluminum, tin, magnesium and cadmium. In addition, some metals can have different shades - arsenic (grayish), lead (bluish-white). Many metals, when crushed, may have uncharacteristic colors, such as red or brown. In addition, most metals oxidize upon prolonged contact with air and, as a result, they darken.

Specific gravity plays an important role not only in gold mining, but also in the production of various alloys. In order for them to be uniform and of high quality, it is necessary to select metals with a slight difference in specific gravity. Otherwise, if the difference is very significant, during fusion the metal, which has a lower volumetric weight than gold, may float.

Only gold and copper of all metals have a special, characteristic and unique color.

Gold turns into a liquid state from a solid at 1095 degrees Celsius.

Specific heat. Denotes the amount of heat that is necessary to increase 1 kilogram of gold by 1 degree Celsius - measured in kilocalories and denoted by the letter C.

Thermal conductivity. This property of a metal to conduct heat is characterized by its thermal conductivity coefficient.

Gold melts at 1095 degrees Celsius.

Hidden melting point. The metal must be heated to the melting temperature and maintained while the crystalline structure is destroyed - until the gold completely transforms into a liquid state. This additional energy is called the latent heat of fusion and is measured in kilocalories.

Electrical resistance - measured in Ohms.

Coefficient of linear expansion (thermal or thermal). Indicates the ability of a metal to increase its size in length (when heated).

Magnetic properties. All metals are divided into: paramagnetic, diamagnetic and pheromagnetic. When introduced into a magnetic field, materials of the diamagnetic group are not attracted to the magnet. Gold is one of the diamagnetic metals.

What kind of gold purity is this – 999?

The concept of “sample” is familiar to almost everyone who has in one way or another encountered the purchase of jewelry. In everyday life, a hallmark is a mark that must be affixed to products made of precious metals (platinum, gold, silver).

Mandatory branding was introduced by Peter I. At the beginning of the 18th century, the Emperor initiated a long-overdue monetary reform and ordered the stamping of gold chervonets, the main state currency. Over time and under the influence of political upheavals, the design of the hallmarks changed, but since then they have always decorated products made of precious metals.

So, 999 gold purity is the highest level of purity of the metal at the moment. The mark with these treasured numbers means that a particular 1-kilogram bar contains 999.9 grams of pure aurum (gold). It couldn’t be purer: even modern technologies do not allow us to obtain 1000 purity gold. This is an unattainable standard, like 100% alcohol or perpetual motion.

In Russia and many other countries, the metric testing system is used, linked to the international SI system. It replaced the outdated spool system back in 1927 and has remained unchanged since then.

In the USA, the karate testing system is used. According to it, the 999th standard corresponds to 24 carats.

Advantages and disadvantages of metal

Jewelry made from 999-karat gold is very expensive - you won’t find it in the general retail chain; it’s exclusive to the wealthiest. One should also take into account the fact that a chain made of such gold will be very unreliable, and losing such beauty will be extremely disappointing.

In order to somehow neutralize the softness of pure gold, products made from it are made very massive. The best option is an exclusive wedding ring weighing 10 grams or more.

The main advantage of this precious metal is its high liquidity: if necessary, it can always be sold at an adequate rate. Gold in measured bars can be deposited: the interest accrues is small, but the precious metal is constantly growing in price.

The cost of a gram of gold may decrease slightly, but compared to currency fluctuations, this is minuscule. In short, if a person wants stability and is not chasing quick super-profits, it is worth investing in gold bars.
