eal gold jewelry is made from real gold. However, 100% pure gold is not used as it would be far too soft and therefore not durable enough for jewelry production. Instead, a so-called gold alloy is used.
Gold alloys:
In simple terms, a gold alloy is a mixture in which gold is mixed with another material. This is necessary to give the gold the hardness required for the manufacture of gold jewelry. The exact proportion of real gold in the alloy can be recognised by the exact designation. For the production of 750 gold (also known as 18 carat gold), 75% real gold and 25% other metals are used.
Gilded jewelry:
Gold-plated jewelry is not real gold jewelry. In gold plating, the jewellery in question is only coated with a thin layer of gold. In most cases, you can only guess what is underneath the gold plating. Plastic, iron or brass - anything is possible.
Recognising genuine jewelry:
At Purajoya every piece of jewelry has a precious metal stamp, because we offer only genuine jewelry.
Genuine gold jewelry: how to recognise high-quality pieces
Tip 1: Genuine gold has an embossed stamp
You have probably noticed a small number embossed in an inconspicuous place on your piece of jewelry. This number is often found on the clasp or on a separate plate. It is the official indication of the fineness of the precious metal. A 750 embossing (18 carat) indicates that 750 gold, for example, was used for your piece of gold jewelry.
Unfortunately, the stamping is not always a very clear criterion. Although the fineness of the precious metal used must be stated in many countries around the world, this is not the case in some countries. It can therefore happen that pieces of jewelry made of real gold are in circulation that cannot be identified by their hallmark. Of course, embossing can also be counterfeit. Nevertheless, you should always consider the presence or absence of a hallmark as a first indication of the authenticity of precious metals such as gold and silver.
Tip 2: Real gold is not magnetic
A magnet may help you if you are wondering if your jewelry is real gold. Real gold is not magnetic. If you hold the magnet near the jewelry, the gold should not feel attracted at all. Gold-plated necklaces and the like are quite different: if they contain iron or other ferromagnetic components in larger quantities, they will clearly react to the magnet.
Unfortunately, the magnetic test is not an infallible sign to distinguish real gold from gold-plated jewelry. Like gold, many materials used in gold-plated jewelry are not magnetic. Copper, brass and the like are therefore not attracted to magnets. Nevertheless, if your jewelry sticks to the magnet, you can be sure that it is not genuine gold jewelry.
Tip 3: Real gold can be detected chemically
If you are still not sure whether your piece of jewelry is made of real gold or just gold-plated after the first two test methods, you can carry out a chemical analysis. You can buy a metal acid test for this. To get started, carefully scrape off a little gold from an inconspicuous area. Then drip the acid onto the scraped gold and read the result. The acid test clearly shows which metal your piece of jewelry is made of.
Conclusion:
With these tips, you can easily tell whether your gold jewelry is genuine or just gold-plated. This way, you can avoid disappointment and be sure that you own a high-quality piece of jewelry.
Alternatively, you can send your jewelry to Purajoya. We will check the authenticity of the jewelry and buy your old gold.
