At present, it is not uncommon for someone to see gold jewelry. But not everyone knows that there are several samples of gold products. In this article, we will examine in more detail the 375 sample, and how it differs from the 585 sample.
What is a gold test?
Gold test is a determination of how much precious metal is contained in an alloy, also these are special brands that are put on the product to ensure that there are noble metals in the jewelry . Legislation carefully monitors both jewelry and the institutions that sell them. There are currently four valid sample systems. Popular gold samples include: 375, 585, 750, 958.
375 gold test: what is it?
Gold products of this sample are among the lowest quality. But in some countries of the world 375 and 333 tests are still recognized. In modern jewelry production, sample 375 is quite rare, since this alloy begins to darken in air after a short period of time. Nevertheless, you can find a lot of jewelry with a mark of 375 gold samples. What it is? This is a sample with a low content of precious metal in its purest form. Its content is only 37.5%, the rest is impurities. This sample has five grades.
How can high impurities affect product properties and color?
- If the percentage of copper is high, then the jewelry will have a deep red or yellow color. Also, copper is able to reduce anti-corrosion properties, which affects the finished product badly.
- If the percentage of silver is high, then the jewelry will be light yellow or even white. Due to the increased silver content, products become more elastic and allow you to create small patterns.
If you do not wear or clean jewelry with such a breakdown for a very long time, then after a certain period these items will darken and become unfit for wearing these items. The 375th test has the main difference from other samples - they are quite durable, but have poor quality.
But you don’t need to completely ignore products with this breakdown, since for a small amount you can buy a pretty decent ring or earrings, and if you provide decent jewelry with these jewelry products, they can please you for many more years. These products have an acceptable price compared to the 750th gold.
Distinctive features of 375 samples
Previously, 375 gold samples were examined in detail - what is it. Now let's pay attention to the distinguishing features of this test:
- Firstly, in this alloy only 37.5% of pure gold (as mentioned earlier).
- Secondly, the alloy in this gold consists of two precious metals - silver and copper.
- Thirdly, in Russia there are only five alloys on which 375 gold samples are allowed to be applied.
- Fourth, these alloys are used in limited quantities, since their quality is low, and over time, products made from them turn into tarnished pieces, which are very difficult to return to its previous attractive appearance.
- Products from alloys of 375 samples can have a shade from yellow to red, everything will depend on the proportion of which alloy prevails.
- The hardest and highest quality are pink alloys.
- The most popular products using 375 samples are wedding rings.
Alloys of gold 375 tests
As already mentioned, the gold of this sample is represented by an alloy of silver and copper. From this it follows that it is possible to distinguish alloys with different percentages of silver and copper:
- If the alloy, where the gold content 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 proportion 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 proportion of gold is 37.5%, the amount of silver is 16%, and copper is 62.5%.
All of these alloys can be safely considered low-grade, and therefore they are not popular abroad. But if you visit the UK or the United States, you will surely come across a huge range of products with 375 samples. Before buying jewelry from the 375th test, it is necessary to study customer reviews in detail about the 375th gold.
Reviews
Many very often, before buying jewelry, first read reviews, look through photo galleries of jewelry stores, study the opinions of customers, and only then make the final choice. On the one hand, this approach can be safely considered correct, since in a store you can be deceived and tell a lot of different tales, only to sell your products. On the other hand, you should not trust everything that is written on the Internet, and even more so on forums about gold of the 375th test. Reviews can be different, because you will not please everyone, and everyone has different tastes.
But if we analyze all the responses, then there will be more negative than positive ones, and this is all connected with the only drawbacks of this test - low quality and fragility. Even this can be argued, since everything will depend on the care of the product and if it is correct, then even a budget product with low quality can last a long time.
What is the difference between gold of the 585th test and 375th?
Next, we will examine in more detail what differences exist between precious jewelry with different samples:
1. Different gold content 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 a high gold content. This has already been said before - 375 gold samples: what is it ?. Products with this breakdown have high strength, and therefore very often get wedding rings with just such a breakdown.
3. Also, products with a high percentage of gold will be significantly more expensive than with a smaller one. Therefore, we can explain the low cost of products with 375 gold breakdowns.
4. Jewelry, that with a 585 breakdown, that with a 375, have strength and lightness, 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 you should pay your attention to such a budget option as 375 gold sample.
