ゴールド

ジュエリー産業で使われる金は、実際には金と他の金属の合金である。これは主に、純金が柔らかすぎる素材であることに起因する。リガチャーを加えることで、特定の化学的・物理的特性を得ることが可能になり、変形しにくいジュエリーを作るのに適した貴金属になるのです。リガチャーは合金の色にも影響する。リガチャーが金に加えられる割合によって、異なる色の合金を得ることができます。 合金の正確な組成は、GOST 30649-99とGOST P 51152-98によって決定されます。合金はアルファベットと数字で表示されます。金は "Zl"、銀は "Sr"、銅は "M"、亜鉛は "Ts"、プラチナは "Pl"、パラジウムは "Pd"、ニッケルは "N "と表示される。数字は添加された不純物の%を示す。例えば、金ZlSrM 585-80は金585に銀8%と銅33.5%を加えたものです。 金の最も一般的な色 宝飾業界では

人々にはこの事実について多くの説明があるが、そのどれもが否定的で、「不吉」とさえ言える。前兆によれば、ゴールド・ジュエリーに黒い部分が現れたら、その持ち主に腐敗や邪眼が課せられていることを意味する。もうひとつのよくある誤解は、ゴールド・ジュエリーが黒くなるのは、人体に深刻な病気が発症していることを示すというものだ。実際には、これはすべて現実とは何の関係もない偏見に過ぎない。

Why are eternal values called eternal? Yes, because both in crises and in periods of prosperity they do not lose their importance. And when hard times come, people try to save their money not in "iPhones" and cryptocurrencies, but in gold. However, this also applies to good times - all financial guides consider the precious metal as a strategic asset, and recommend investors to keep at least 5-10% of their portfolio in gold.

Well, and under the bright shine of gold can hide inexpensive silver or ordinary steel. And doubly offensive, if for a modest bijouterie you will pay as a luxury "jewelry".

Another option is also possible, less criminal. Suppose you inherited jewelry, and you want to know whether they are real or only imitation. Or maybe a ring or earrings were given to you as a gift by an admirer? A gift horse, of course, do not look in the teeth, but still curious - how highly you are valued, and how seriously they treat you? Simply put, is the jewel…

When a loved one passes away, many heirs do not know what to do with their belongings.

How to act correctly? Is it possible to wear gold after a deceased relative, is it not dangerous, will not be perceived as sacrilege?

Superstitions and omens
