図1.真鍮と金の見分け方

ジュエリーを "手売り "や怪しげな場所で買うことは、大きなリスクを伴う。お金もなく、宝石もないままになる危険性がある。指輪や珍しいコイン、イヤリングをプレゼントするつもりだった場合は、特に恥ずかしい思いをすることになります。ですから、ジュエリー・サロンを無視して、見知らぬ人から「ジュエリー」を買ってはいけません。また、知人でさえも、偽物を所有していることに気づいていない可能性があります。特に、偽物のジュエリーによく使われる真鍮は、見た目が金によく似ているからだ。もし、あなたがその誘惑に勝てず、そのジュエリーの値段が「指を舐めるような値段」であるなら、民間の方法が助けになるでしょう。ここでは、家庭で真鍮と金を見分ける方法をご紹介します。

金と真鍮の見分け方

まず初めに、真鍮と金の原理的な違いを理解しよう。金は貴金属と銅や銀などの合金のこと。真鍮もまた、すべての...

ゴールドは紛れもなく価値のある金属であり、ゴールド・ジュエリーは格調高く、非常に美しく、魅力的である。しかし、宝石店で新しいきらびやかなイヤリングやファッショナブルな指輪を買う機会がいつも、そして誰にでもあるわけではない。この場合、最初に考えるのは質屋に行くことだ。しかし、たいていの人は即座にそれを拒否する。なぜなら、他人のジュエリーは自分を傷つけるという固定観念があるからだ。

相続や年配の親族からの贈り物で、他人のジュエリーの所有者にならざるを得ないのだ。楕円形の合成ルビーがついた饒舌で大きな指輪や、強力なカラビナがついた巨大な「ビスマルク」チェーンなど、家宝を大切な箱に入れて持っている人が大勢いることは確かだ。そしてまた同じ疑問が生じる--身につける価値があるのだろうか？質屋で買った他人の金、あるいは受け継いだ他人の金を身につけることができるかどうか、考えてみよう。

The wedding day is approaching. And there's so much to do: order this, pick up that, discuss... buy... Stop. And the wedding rings are not forgotten? That's the most important thing! What are the criteria? Design, size, and proof. Oh, and color, of course. So, what color gold to choose? The grade 333 or 375, 500, 585 or 750? For those who have ever been to a jewelry store, this question needs no explanation. Of course, we are talking about the grade, which means the content of gold itself in the product. The highest grade - 999 - means that the alloy contains 99.9% of the precious metal. But you will not find rings, bracelets, earrings and pendants of 999 grade on sale. The thing is that pure gold is a very soft, plastic material, and a ring made of it cannot be worn every day - even fingernails will leave scratches on the surface. Only investment and banking products - bars and coins - are made of 999 grade metal. For jewelry, gold alloys and ligatures are used - metals ad…

Gold assay is a marking that indicates the ratio of pure gold and impurities in the alloy. The fact is that 100% gold is a very soft material. So much so that it can be crushed with fingers. Therefore, in jewelry and a number of other industries use an alloy of gold with ligature (additives). As a ligature can be used: Copper. It gives the gold a hardness and a red tint. This variant of the alloy was especially popular in the USSR, the so-called "red gold". Zinc. Increases the fluidity of the material, at a certain percentage in the alloy can give an emerald hue. Platinum. Increases the melting point, gives gold a special glow. Silver. Increases casting properties, gives hardness to products and makes gold lighter in color. Nickel. Makes the alloy harder, protects against corrosion. Gives a lighter color to gold. Palladium. Increases the melting point, makes the metal more ductile. The alloy is characterized by a light shade. Cadmium. Increases casting properties…

Gold and silver are some of the most popular jewelry metals. Both are used in the form of alloys, as they are too soft and malleable in their pure form. Gold, which is originally yellow in color, turns white due to the addition of silver, platinum, palladium and nickel. Products made of it are extremely similar to silver. Therefore, the owner of a piece of jewelry often faces the question - is it white gold or cheaper silver? We tell you how to distinguish white gold from silver. Visual differences Jewelry made of white gold has a warmer shade. Silver has a steely, cold color. The shine of gold is brighter, lacquered. Silver is more matte, dull. The easiest way to notice the differences in halftones and shine is to put the products side by side. Pay attention! If a jewelry piece has a rhodium-plated coating, visually both silver and gold will look the same! Marking Gold and silver jewelry must necessarily have a hallmark. It is usually located on a small, inconspicuous area: …
