金色

珠宝业使用的黄金实际上是黄金和其他金属的合金。这主要是因为纯金是一种太软的材料。加入连接剂后，就可以达到一定的化学和物理特性，使这种贵金属适合制作不易变形的首饰。连接剂还会影响合金的颜色。根据在黄金中添加的比例，可以得到不同颜色的合金。 合金的确切成分由 GOST 30649-99 和 GOST P 51152-98 确定，这两个标准规定了添加到黄金中的金属比例。合金上标有字母和数字。金标注为 "Zl"，银标注为 "Sr"，铜标注为 "M"，锌标注为 "Ts"，铂标注为 "Pl"，钯标注为 "Pd"，镍标注为 "N"。数字表示添加杂质的 %。例如，ZlSrM 585-80 金是 585 金，添加了 8% 银和 33.5% 铜。 最常见的黄金颜色 在珠宝行业中，...

耳环、戒指、吊坠、链条、手镯等我们佩戴的任何黄金首饰都会随着时间的推移而变黑。这无疑是非常令人沮丧的。让我们来看看黄金变黑的原因。让我们试着了解是否有可能防止或减缓这一过程，以及如何做到这一点。

人们对这一事实有很多解释，但都是负面的，甚至可以说是 "不祥的"。根据预兆，如果黄金首饰上出现黑色区域，就意味着首饰的主人受到了破坏或邪眼的侵扰。另一个常见的误解是，金饰变黑表示人体正在罹患某种严重疾病。事实上，这只是一种偏见，与现实无关。

A favorite jewelry box, with gold and silver jewelry lovingly arranged in soft nests. You probably have one of those. And how do you choose what to wear today? On what principle?

Figure 1. Testing gold for authenticity

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.

Jewelry is also an investment. First of all, it is an asset, and therefore their purchase should be approached as pragmatically as possible.

How to check the authenticity of gold at home? This is what we will talk about in this article.

As long as mankind has existed, so long has deception lived in the world. Buying gold jewelry "by hand", on the Internet or in some other dubious places is always fraught with risk. For example, a diamond can be tested as a fianite, zircon, muassanite, which is very similar to a diamond, but costs 20 times cheaper. Or even just a piece of crystal glass. 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…

So, if the ring has a 750 grade (the most common)…

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
