Medical gold: what is it and how to clean it?
Medical gold is actively used to create various products.... Jewelry made from this alloy is traditionally especially popular among many consumers. After all, they have a very stylish and beautiful appearance, moreover, they are particularly durable. However, not everyone is sure whether to buy such products. After all, there are many myths associated with them.
What is it and how is it different from ordinary gold?
To understand this issue, it is necessary to learn in more detail everything about this alloy.
First of all, it is worth noting that medical gold received this name only because it was originally used for the manufacture of surgical instruments, as well as for the manufacture of crowns.
However, over time, this has become less relevant. That's why this alloy began to be used for the manufacture of jewelry.
Here are the main pluses.
- It is worth noting the great similarity with real gold. It's not just about visual similarity.
- Such material has rather high plasticity indices, which makes it possible to make products of unusual shapes out of it.
- It should be noted the high strength of medical gold. It is not afraid of any mechanical stress.
- In addition, this alloy is also popular because it does not cause allergic reactions, as well as side effects, even with regular wear.
- Such material does not oxidize, does not change its color even when exposed to water.
- What many like especially is its visual resemblance to 750 gold.
- And, of course, the main advantage is the low cost of such products.
Medical gold contains a large number of different metals.: and silver, and copper, and titanium, and even zinc. But what is characteristic, despite this name of the metal, gold itself may not be in the composition at all.
Since medical gold looks very much like a real metal, you need to know how to distinguish it, which is important when buying. After all, there are a large number of scammers who in any way try to deceive ignorant people.
To prevent this from happening, everyone jewelry is recommended to be purchased in specialized stores.
But if this is not possible, then it is worth knowing the following.
- Items made of real gold have a standard, thanks to which you can find out the amount of precious metal in the alloy.
- Jewelry made of medical gold has no purity. After all, the noble metal is used here only in small quantities. However, it may not even be in the lineup.
- If the products are not properly cared for, then they will lose their attractiveness over time.
- Price also plays an important role. If the seller of such jewelry offers to purchase a product of the highest standard at a large discount, then the buyer in this case needs to be wary and think about whether to make such a purchase. Before purchasing jewelry, be sure to familiarize yourself with the prices for jewelry.
- You also need to know that real rare and expensive stones are never framed in such an alloy. Accordingly, it is simply impossible to buy jewelry with sapphire or diamond made of medical gold.
You can also test the offered gold. It is enough to drop just one drop of iodine on the inside of the product... In the event that it is real gold, a dark speck should remain in the place of the drop. Medical alloy will not react to iodine; it will be enough to simply wipe it off. There will be no damage left.
When evaluating, it is also necessary to determine the weight of the decoration.... After all, real connoisseurs know that gold items, especially of high standard, are rather massive and heavy. Concerning medical alloy, it is lighter and more shiny. However, if a person is completely ignorant in such matters, then it is worth seeking help from a real specialist. This will not only allow you to avoid troubles, but also save you from unnecessary worries.

This option is not so reliable, because over time, the spraying is very quickly erased.
Especially if a person uses it too actively.
Does it turn black?
Almost all items made of medical gold retain their original appearance for a long time. They do not darken even in salt water. The only thing that can affect medical gold is time.
After a certain period, the coating wears off, steel begins to show through.

Care features
In order for the purchased medical gold products to serve as long as possible, you need to provide them with proper care. First of all, you need to store them separately from other jewelry. For example, a large box with a certain number of cells will do.
In this case, the products will not come into contact with each other, which means they will not be able to be scratched or otherwise damaged.
Besides, do not use plastic boxes or plastic bags for storage... After all, they are completely unsuitable for a medical alloy, the jewelry in them will simply darken.

Another effective remedy is regular chalk. For cleaning, you need to rub the darkened jewelry with chalk, and then remove all residues with a slightly damp cloth. Also you can use the following solution:
