At present it is not uncommon for someone to seegold jewelry. But not everyone knows that there are several samples of gold items. In this article we will examine in more detail the 375 sample, and how it differs from the 585 test.
What is the test of gold?
A gold sample is a definition of how muchcontains precious metal in the alloy, also it is a special brand that is put on the product to ensure that there are noble metals in the decoration. Legislation closely monitors both jewelry and institutions that implement them. Currently, there are four active sample systems. Popular gold samples include: 375, 585, 750, 958.
375 gold sample: what is it?
Products made of gold of this sample belong to the mostlow-quality. But in some countries of the world 375 and 333 samples are still recognized. In modern jewelry production, the 375 sample is rare, since this alloy begins to darken in the air after a short period of time. Nevertheless, you can meet a lot of jewelry with a mark 375 sample of gold. What it is? This is a sample with a low content of precious metal in its purest form. Its content is only 37.5%, all the rest is impurities. This sample has five marks.
How can a high content of impurities affect product properties and color?
- If the percentage of copper is high, then the jewelry will have a rich red or yellow color. Also, copper is able to reduce anti-corrosion properties, which badly affects the finished product.
- If the percentage of silver is high, thenthe jewelry will be light yellow or even white. Due to the high content of silver, the products become more elastic and allow the creation of small patterns.
If you do not wear or clean for a very long timejewelry with such a breakdown, then after a certain period of time, these gold items will become dark and become unsuitable for wearing. 375-th test has the main difference from other samples - they are quite durable, but have a low quality.
But you do not need to completely ignore the products withthis sample, because for a small amount you can buy a decent ring or earrings, and if you provide these jewelry products with a decent care, they can make you happy for many more years. These products are quite affordable compared to the gold of the 750th test.
Characteristics of 375 samples
Earlier, 375 samples of gold were examined in detail - what is it. And now let's pay attention to the distinctive features of this sample:
- Firstly, in this alloy, only 37.5% of pure gold (as already mentioned earlier).
- Secondly, the alloy in this gold consists of two precious metals - silver and copper.
- Thirdly, in Russia there are only five alloys, which are allowed to apply 375 samples of gold.
- Fourthly, these alloys are used inlimited quantity, as their quality is low, and over time, products made from them turn into tarnished pieces, which are very difficult to regain the former attractive appearance.
- Products from 375-alloy alloys can have a shade of yellow to red, everything will depend on which share of the alloy is predominant.
- Alloys of pink color are considered to be the hardest and highest quality.
- The most popular products with the use of 375 tests are considered wedding rings.
Gold alloys of 375 tests
As already mentioned, the gold of this sample is represented by an alloy of silver and copper. It follows that it is possible to identify alloys with different percentages of silver and copper:
- If the alloy, where the share of gold is 37.5%, has a bright red color, the amount of silver will be only 2%, and copper - 60.5%.
- If the alloy has a red color - the share of gold is 37.5%, the amount of silver will be only 10%, and copper - 52.5%.
- If the alloy has a red color, the share of gold is 37.5%, the amount of silver is 16%, and copper is 62.5%.
All of the listed alloys can be safely assumedbase, and therefore they are not popular abroad. But if you visit the UK or the United States, you will certainly come across a huge assortment of products with 375 breakdown. Before buying a jewelry from 375 tests, you need to study in detail about the gold of the 375th test of customer testimonials.
Reviews
Many very often, before you buydecorating, read reviews first, view photo galleries of jewelry stores, study the opinions of buyers, and only then make the final choice. On the one hand, this approach can be safely considered correct, because in the store you can be deceived and tell a lot of different stories, only to sell your products. On the other hand, you should not trust everything that is written on the Internet, and even more so in the forums about the gold of the 375th test. Reviews can be different, as everyone does not please, and everyone has different tastes.
But if you analyze all the responses, it will bemore negative than positive, and this is all due to the only drawbacks of this trial - low quality and fragility. Even with this one can argue, since everything will depend on the care of the product and if it is correct, then even a budget product with a low quality will last for a long time.
What is the difference between the gold of the 585th test and the 375th?
Next, we will consider in more detail what are the differences between precious jewelry with different samples:
1. Different contents of gold in the product: in 375 samples - 37.5%, and in 585 samples - 58.5%.
2.Strength in products with a low gold content is higher than in products with high content. It has already been said earlier about this - 375 gold test: what is it ?. Products with this sample have high strength, and therefore very often they get wedding rings with such a test.
3. Also, products with a large percentage of gold will be significantly more expensive than with less. Therefore, it is possible to explain the low cost of products with 375 breakdown of gold.
4. Jewelry, that with 585 breakdown, that with 375, have strength and ease, and these qualities allow you to create masterpieces.
If you do not pay attention to the imposed norms and stereotypes, but still give preference to wear resistance and practicality, then it is worth looking at a budget option such as 375 gold sample.
