They all differ in a certain level of difficulty, the cost of production, and the quality of the resulting product. &nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Real alloy with ligatures<\/h3>\n\n\n\n<p>The melting of gold with a mixture of cobalt and chromium gives the metal, which then undergoes oxidation at a temperature of 700-950 degrees. It is cobalt that gives the resulting alloy a black color, and in combination with chromium is responsible for the strength of the material. The final product is poorly processed, which is why its cost is much higher than that of yellow gold. <\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-style-check is-layout-flow wp-block-quote-is-layout-flow\">\n<p>This is the only manufacturing method that allows you to get a rich black color that will not change over time.<\/p>\n<\/blockquote>\n\n\n\n<figure class=\"wp-block-image size-large is-style-default\"><span itemprop=\"image\" itemscope itemtype=\"https:\/\/schema.org\/ImageObject\"><img itemprop=\"url image\" loading=\"lazy\" decoding=\"async\" width=\"870\" height=\"600\" src=\"https:\/\/drago-met.ru\/wp-content\/uploads\/2021\/04\/CHernoe-zoloto-3-1.jpg\" alt=\"Real alloy with ligatures\" class=\"wp-image-10028\" srcset=\"https:\/\/drago-met.ru\/wp-content\/uploads\/2021\/04\/CHernoe-zoloto-3-1.jpg 870w, https:\/\/drago-met.ru\/wp-content\/uploads\/2021\/04\/CHernoe-zoloto-3-1-800x552.jpg 800w, https:\/\/drago-met.ru\/wp-content\/uploads\/2021\/04\/CHernoe-zoloto-3-1-580x400.jpg 580w\" sizes=\"auto, (max-width: 870px) 100vw, 870px\" \/><meta itemprop=\"width\" content=\"870\"><meta itemprop=\"height\" content=\"600\"><\/span><figcaption class=\"wp-element-caption\"><strong><span class=\"has-inline-color has-black-color\">Gold alloy ligatures<\/span><\/strong><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Traditional yellow metal rhodium plating<\/h3>\n\n\n\n<p><a href=\"https:\/\/drago-met.ru\/en\/zoloto\/rodirovanie-zolota-sut-protsessa-zachem-eto-pokrytie-tehnologiya-plyusy-i-minusy-protsedury\/\" title=\"Gold rhodium plating: the essence of the process, why this coating, technology, pros and cons of the procedure\">Roding<\/a> is the process of plating yellow gold with a layer of rhodium.

This kind of jewelry is popular among black gold fans who are not willing to pay a fortune for costume jewelry. Jewelry has the same properties and attracts attention with its color, but the cost is significantly lower. When the color starts to fade, the black plating can always be renewed.  <\/div><\/div><\/div>\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>\u0420\u043e\u0441\u0441\u0438\u044f
