Urgent questions about platinum, a collection of trivia about platinum

Generally speaking, we discourage changes in positions, but if they do need to be changed, how do you make the perfect change? Please note the following three questions and screen them at the time of purchase:

1 The first thing to do is to determine if the bracket can be changed. This question is often a litmus test. If you meet someone who is doing business with integrity, then he may be honest with you about what can and cannot be changed, or the problems that are likely to arise after changing your position; If you meet a jeweler with a lust for money, he'll just tell you one thing:

There is no hand size that cannot be changed! In fact, brackets that are too slim in order to pursue sleek lines should avoid changing sizes. If you don't have the know-how, then there is a simple criterion to grasp in the actual buying process:

If the total weight of the diamond ring is below the gram (including the weight of the diamond itself), then it means that the amount of gold used is less, the ring is relatively thin, and the external force applied when changing the hand size can easily cause injury, so you should change the hand size carefully. In addition, if there are fewer stress points on the bracket to hold the diamond, such as a two-point fixed or three-point fixed style, you must be cautious (please refer to the previous article "Which styles of diamonds are prone to falling off?"). >>

2. Must have a complete set of equipment and processes. Changing the size of a hand is nothing more than two cases: small to large and large to small.

In the case of small to large, if the size change is small, qualified jewelers can change the size by hand grinding (thinning), machine polishing and other processes, but the premise must be based on the original gold consumption and the rich foundation of the ring itself! In the case of large and small dimensional changes, then the original finger ring must be cut. Considering the factors of fire safety, many jewelry stores do not have special equipment such as gas welding, so they work around, so it is easy to leave traces of changes at the interface and fly in the ointment!

It is also important to note here that many stores are very sloppy about the service of changing the size, often reducing the polishing process and time (who made you pay for it?!).So many customers often complain that it is better not to change their size!

3. Excellent craftsmanship and responsible attitude. This is often an afterthought! Generally speaking, changing the size of the store is restricted by various factors, and it is difficult to reach the level of the original production and processing in the factory.

Especially when you encounter an inexperienced or irresponsible master, then you only care about the size of the finger ring and don't care about anything else!

In short, the points mentioned here can only be a reminder for you. There are different opinions on the situation, and it is impossible to generalize. (From Yingjin Diamond Blog).

Gold is malleable, and it can be changed to size without adding gold, and your ring weight is light, it is estimated that there is no gold at all, and 40 yuan is your processing fee!

1. Basic knowledge of platinumPlatinum (PT) is a naturally occurring precious metal with a white beam. It originated 2 billion years ago, when a huge meteorite struck the Earth, bringing this precious metal with it. Platinum has shone in the history of human civilization as early as 700 BC, and in the more than 2,000 years of human use of platinum, it has been considered the most noble metal, sought after by noble royal families.

King Louis XVI of France once declared platinum "the only *** fit for a king". The Duchess of Windsor said, "After five o'clock in the afternoon, you should wear platinum."

2. Comparison of platinum with other ***The common name of platinum is white gold, platinum gold is pure white, and the reserves of platinum in nature are scarcer than those of the auspicious situation, so it is more expensive than **. Platinum can make the white diamond maintain its original color, and it is very strong, it is the best material for setting diamonds, and it is the diamond that makes platinum the superstar of jewelry. In China, most of the colors used in jewelry inlay are PT950 and PT900, and PT900 is the most commonly used.

3. Common sense of platinum jewelryGold is a natural white color. Platinum is mined annually at only one-twentieth of the highest level, and an ounce of platinum takes five months to extract from 10 tonnes of platinum ore. Platinum jewelry is very flamboyant and looks extra temperamental when worn on the body, but if your platinum jewelry is not well maintained, it will quickly become dull.

Platinum is a naturally occurring material.

Its main component is platinum, platinum in the classification of minerals, is a natural platinum subgroup, including iridium, rhodium, palladium and platinum natural element minerals, the atomic weight of platinum is, atomic number 78, it belongs to the transition metal slightly less than the atomic weight of gold. The melting point of platinum is 1772, the boiling point is 3827 100 and the density is, it is characterized by a soft texture, and has good ductility, thermal conductivity and electrical conductivity.

Platinum is often referred to as white gold, it has always been considered one of the most noble metals, because platinum is not only very small, but also very stable, and the production process is also very complex, so it is also relatively high. At present, the common platinum on the market is actually an alloy, which is mixed with other *** substances, platinum jewelry usually has the symbol of pt, and now the most common is pt950, which is platinum with a purity of 95%.

Platinum (PT) is a naturally occurring white precious metal. Platinum has shone in the history of human civilization as early as 700 BC, and it has been considered one of the most noble metals in the more than 2,000 years of human use of platinum.

In the mineral classification, platinum group element minerals belong to the natural platinum subgroup, including iridium, rhodium, palladium, and platinum. PGE minerals are equiaxed, with very rare single crystals and occasional cubic or octahedral fine grains.

Platinum is a natural white color***.

According to the national jewelry standard, only platinum can be called white gold. In addition, only jewelry with a platinum content of 850 or more can bear the exclusive mark of platinum - platinum (platinum, white gold) or pt.

Platinum metal is often used to make various reaction vessels, such as evaporation dishes, crucibles, electrodes, platinum plates, platinum meshes, etc. In addition, it can also be used to manufacture medical devices such as dental crowns, surgical nails, and surgical tools. Of course, the most well-known use of platinum is in platinum jewelry.

Nature of platinum

Pure platinum is a shiny, malleable, silvery-white metal. It is the highest malleability of all pure metals, outperforming gold, silver, and copper, but its malleability is lower than gold.

Platinum metal is extremely corrosion-resistant, very stable at high temperatures, and has very stable electrical properties. Platinum metal also has high chemical stability, oxidation resistance and corrosion resistance, and will not corrode and rust when exposed to air or heated at high temperatures.

In fact, in essence, platinum is platinum, these two things are actually a substance, but different places are called different, according to international regulations, only platinum can be called platinum.

Platinum (PT), commonly known as platinum, is usually as high as 90%-95%, and the purity of common platinum jewelry is PT900 and PT950. According to national regulations, only jewelry with a platinum content of 85% and above can be called platinum jewelry, and platinum jewelry is extremely pure.

Platinum = White Gold = PT ≠K White Gold. White gold and platinum are the same metal, and it is internationally stipulated that only platinum can be white gold, and people often refer to white gold. White gold is a naturally occurring white metal, a metal with high density, ductility, and low reactivity, and is often used to make a variety of fine jewelry.

Platinum Care Tips:

1. Avoid platinum necklace contact with chemicals in life, such as cosmetics, household cleaners, oil stains, soot, etc.

2. Avoid scratches on platinum necklaces, diamonds are hard, platinum necklaces should be stored separately when not in use, so as to avoid scratches and wear caused by necklaces and other jewelry, and also avoid deformation of platinum necklaces.

3. To prevent the fading of platinum necklaces, in addition to corrosion and oxidation, sun exposure and baking will cause the fading of platinum necklaces. Platinum necklaces that are damp should be dried in time to prevent them from oxidizing.

4. Clean frequently, platinum necklaces can be cleaned in time with warm water and neutral cleaning agents when they are dirty, and they should be dried in time. This method protects the platinum necklace from corrosion and oxidation caused by substances.
