Incredibly chic and amazingly beautiful gold 750: composition, properties, product care, photo, difference from 585

Gold is a natural material known to mankind for several thousand years. Jewelry and decor items were made of noble metal, coins were minted. The beauty of gold products was admired, and their brilliance was compared to sunlight.

A man raised gold to a pedestal of worship, endowed it with a symbol of wealth and high social status. To this day, the passions of gilding do not fade away. Jewelry made of noble metal of high standard is still highly valued and means belonging to a special stratum of society. In the jewelry market, items from 750 samples are the leaders in the number of sales.

What does 750 proof mean?

The noble metal in its pure form is rarely used. This material is completely impractical, albeit beautiful. On the Mohs scale, the hardness value is 2.5. This means that a ring made of pure gold, having fallen from a height of only one and a half meters, is deformed so much that it will be impossible to put it on a finger. And a flat plate made of natural nugget can be easily rolled into a tube.

Given this property, a person has long learned to combine gold with impurities that improve its characteristics. The resulting alloy is suitable for the manufacture of various products.In order to have an idea of ​​the amount of natural nugget in an alloy, humanity has come up with a spool and lot evaluation system. A couple of centuries later, carat and metric systems came into use, which are still popular today.

In Russia, a metric classification is used, based on the ratio of the amount of real gold in grams per kilogram of the alloy. The grades of yellow metal from 375 to 999 have been developed. Connoisseurs of gold items prefer the expensive 750 grade. Samples marked 750 contain 75.5% pure noble gold. The rest of the volume is filled with impurities, called ligature.

The carat system divides the sample into 24 parts. If a thing is marked 18K, then this means that 18 parts are occupied by pure gold, 6 parts are ligature.

The conglomerate of this brand corresponds to 18 carats.

750 gold contains a good ratio of noble nugget and impurities, which allows it to be processed and polished without damage, to create expensive jewelry.

And due to the properties of plasticity and malleability, it is used to make important parts in measuring instruments.

Price

Products of 750 marking have a high cost, but, despite this fact, they are in demand in the jewelry market. Participants in the trading process, producers and consumers, track the price per gram of gold. It can change, its value is influenced by several aspects:

• the cost of a noble nugget in the world market;
• price approved by the Central Bank of the Russian Federation for the yellow metal;
• complexity of the product, payment for the work of the master;
• production costs in industrial conditions;
• mass, color;
• manufacturer's reputation.

The average cost is formed from monitoring prices in purchases, pawnshops, and jewelry stores.At the beginning of autumn 2019, the average price for 1 gram of 750 gold is 3,500 rubles.

For comparison, 1 gram of 585 brand is one and a half times cheaper than 750.

What is the difference between samples 585 and 750?

Buying jewelry, buyers often make a choice based on value for money. Connoisseurs who value the status and awareness of an expensive product in stock choose a 750 sample. Buyers who prefer more economical, but at the same time high-quality material, purchase items marked 585.

Gold in its structure is an amorphous material. Daily wear of jewelry leads to the rapid appearance of scratches and deformation. Copper, nickel, platinum, silver as alloying components improve the strength characteristics of the alloy.

The grade under consideration contains 25% impurities. Such jewelry will not endure constant wear, their appearance will deteriorate under the influence of external conditions. Products labeled above 585 are more suitable for one-time exits, special occasions.

The yellow metal of 585 samples contains a larger amount of alloying components. Products made from this material are more resistant to mechanical stress, resist corrosion well, and have high strength. Jewelry made from low-grade raw materials can be worn daily without any fear for their condition.

From raw materials 585 brands create jewelry, simple in form, without additional elements. For premium goods, this brand is not used, as it does not lend itself to complex decorative work due to its high strength.

A distinctive feature of high-quality raw materials is pliability to processing and polishing.This alloy allows you to create complex elegant compositions, with ornate weaves and openwork patterns. Currently, precious jewelry is popular, in which noble raw materials are covered with enamel.

Composition and properties

Alloying components improve the performance of the alloy. In the raw materials of the brand under consideration, impurities make up 25%. Additives not only increase the values ​​of hardness, strength, but also change the shade:

• Yellow color is inherent in an alloy containing 17% silver and 8% copper.
• Pink color is obtained with 12.2% silver and 12.5% ​​copper.
• Stunning platinum white color is created by 5% silver and 20% nickel.

Gold marked 750 resists the environment more weakly than other samples. This is due to the smaller amount of ligature compared to other varieties of gold.

The high-grade noble metal is in demand in the jewelry market due to a number of advantages:

• malleable to processing, you can create a complex piece of jewelry from it;
• well polished;
• contains a high content of pure gold.

However, the advantages dictate the disadvantages. This metal is characterized by deformation due to the slightest load. The product needs care, otherwise it loses its luster and attractiveness.

Jewelery made from high quality raw materials should be stored in a separate box, in an additional velvet bag. The metal has increased softness, can be deformed or scratched in contact with other products.

Products and decorations

Highly labeled items belong to the premium class, no one wears them in the daily hustle and bustle. These jewelry items are for ceremonial exits. Plasticity allows you to perform complex carved elements, openwork patterns. The beauty of an item depends on the skill of the jeweler.

The noble metal of a high grade is not involved in mass production. Basically, single, exclusive products with inserts of precious stones are created from it.

Impurities in certain quantities expand the gamut of shades of the sample. In the traditional version, the raw material has a yellow color, wedding rings, earrings, chains are made from it. Nickel and palladium as a ligature color the alloy white. Such material is valued for framing diamonds. The cost of the resulting products is incredibly high, especially if platinum is present in the gold alloy.

Caring for 750 gold pieces

Noble high-grade metal behaves capriciously. The components included in its alloy react with carbon dioxide, oxygen, changing the color of the sample. The material is subject to deformation under minimal loads.

The properties of the alloy dictate the rules for storing things from it. Jewelery should not be worn every day, but during dirty and physical work. Personal boxes are suitable for storage. Polishing with a felt cloth will help restore shine. Water procedures are best arranged under running warm water without detergents. Be sure to wipe dry with a soft cloth. Store in places not accessible to moisture penetration.

Items made of high 750 gold are considered an element of luxury. The alloy contains a minimum amount of impurities, amazing natural beauty and brilliance. Framing gems, looks chic and has a corresponding value.
