Rare 985 gold test raises many questions for people who are new to jewelry. Not so much is known about what it is - the metal is quite soft, you will not find it on store shelves in the form of rings and earrings. The features of white and other 985 gold, its composition should be studied in more detail so as not to fall into the tricks of fraudsters when buying.
What it is?
A rare 985 gold test indicates that 98.5% of pure noble metal is present in the alloy.. And also in its composition may include a ligature based on copper and silver. If palladium is added instead, white gold is obtained - a material with a noble luster and a light shade of the surface. Even in a volume of 1%, this metal provides yellow lightening, but it will not be as intense as in the case of low-grade compounds.
At the moment, only samples officially exist in Russia 585, 750 and 958. Sample 985 indicates that the material is as close as possible to pure native gold with all its advantages and disadvantages, and the product itself is released abroad. In the carat system, it corresponds to a value of 23 carats, almost the highest among existing ones. It is characterized by intense shine and a bright yellow color.
Like other high-grade alloys, such gold is very soft, easily deformed.
Advantages and disadvantages
The obvious advantages of pure 985 gold include high cost and value - investing in such a precious metal can definitely be considered a profitable investment. Especially when buying gold in the form of ingots, coins. The unique color of the metal, corresponding to the natural, is also highly valued.
Gold 985 also has disadvantages, and they are directly related to its practical application. This alloy is very soft, easily damaged, deforms under compression without visible effort.
Soft metal pretty quickly worn away, losing weight. That is why it is not used for the manufacture of traditional jewelry used for continuous wear.
Fields of application
985 Gold rarely used in jewelry due to its softness. It is found as decorative parts on complex expensive jewelry that is not customary to wear every day. Massive wedding rings are made of white 23-carat gold - the large thickness of the metal allows to increase the mechanical strength of the product.
Otherwise, the use of this alloy is relevant for the following areas:
- dental;
- electronic;
- chemical;
- investment.
985 gold is used for the manufacture of gold bullion in the banking sector. Valuable investment coins are cast from it.
And also high-grade gold is used as a coating for less noble metals. Chemical neutrality makes gold the perfect solution dental crowns and orthopedic structures in dentistry.
How to choose?
When choosing jewelry from 985 gold, it is worth considering that in Russian stores, such jewelry is not officially sold. The maximum purity of the metal in this case can be 95.8%. In pawnshops and thrift stores it can be found. That's just the assay mark will look completely different. It will have the number 23 and the letters K, Kt, C, CT - the exact designation depends on the country of production.
The color scheme of high-grade gold is originally bright yellow. And also there are options in white, red, pink, green. Regardless of the ligature, the main tone will remain unchanged, it will acquire only a slight additional shade.
When choosing this is worth considering. Even white high-grade gold will be saturated yellow, if the product is silver, this is clearly a cheap fake.
Softness - Another feature of this alloy with 98.5% pure gold. The metal is easily damaged and deformed even with light pressure. If this does not happen, we are talking about a lower composition.
When making to order, jewelers recommend taking 98.5% alloy only for the decorative part of the jewelry: twisted elements and complex curly parts laid on top of a firmer base. In this combination, you can create spectacular earrings and other art products, increasing their value.
When buying abroad, it is important to pay attention to the fact that a certificate and a check should be provided on the products, in which all related information will be indicated in detail. There are countries from which it is officially impossible to export gold to the Russian Federation: it is worth examining the list before you go shopping.
How to care?
All types of high-grade gold need careful treatment and careful care. A few simple recommendations should be followed.
- Storage separate from other jewelry. Preferably in a special case. The joint storage or contact of metal products with different hardness indices should be excluded.
- Refusal of constant wearing. Products made of high-grade metals are worn on special occasions. With constant wear, they quickly wear out, and from contact with sweat, they become dull with skin oil and lose their luster. Perfume and cosmetic formulations cause oxidation on contact with metal.
- Protection against household chemicals. For gold 985 samples, contact with chlorinated and sea water, household chemicals and other reagents is harmful. In this case, be sure to protect your hands with gloves.
- Refusal of self-cleaning. It is important that a professional deals with this matter, since ultrasonic instruments used in the jewelry industry do not require mechanical action on the material. Home polishing and cleaning will spoil an expensive item.
- Refusal to wear at high and low atmospheric temperatures. High-grade metals are so sensitive to external influences that even heat or frost can lead to deformation and cracking of their surface.
All these tips will help to keep the products of 985 gold in excellent condition, exclude the loss of valuable metal or its natural properties.
