Among the many precious jewelry metals green gold <\/strong>It attracts with its elegance. Green combined with gold evokes a wide variety of associations, and each person has their own. Green gold <\/strong>The technique, which emerged in the 1970s, produced a metalloid from 18-karat gold. The term "metalloid" refers to a precious metal compounded with another metal, which acts as an alloying additive. Such additives include silver, copper, and cadmium. Their proportions vary and they have different melting points. Therefore, to achieve the required alloy consistency and create a homogeneous material, several alloying stages are required.<\/p>\n\n\t\n\t\n

Technological process of smelting green gold <\/strong>It is kept strictly confidential and known only to a limited number of jewelers and metallurgists who specialize in this craft. This smelting process allows gold to acquire strength, hardness, and a certain wear and scratch resistance. During smelting, the chemically active alloy does not form electron bonds with the gold atoms, which is why green metalloids often turn out brittle. This is especially characteristic of the creation of green gold <\/strong>from the production of alloy steels or aluminum-based alloys.<\/p>\n

Today there are four alloys green gold: <\/strong><\/p>\n

    \n
  1. Light greenish gold containing 23% copper and 2% cadmium in the alloy;<\/li>\n
  2. Soft green colour containing 25% silver;<\/li>\n
  3. Pure green, which contains 20% silver and 5% copper;<\/li>\n
  4. Rich green in color, it contains 15% silver, 6% copper, 4% cadmium.<\/li>\n<\/ol>\n\n\n\n\t\n

    Jewelry of 750 assay value is made from all four of these types of gold, each of which emphasizes its own specific zest and beauty. Also green gold <\/strong>Green gold can be obtained from other alloys, such as potassium, zinc, and alkali metals. However, green gold can irritate the skin, so jewelry made from this metal should be selected strictly individually.<\/p>\n

    Certain requirements are imposed on jewelry metalloids:<\/p>\n

      \n
    • be sufficiently hard, chemically inert, and not reacting with oxygen;<\/li>\n
    • have plasticity so that it can withstand torsion and stretching;<\/li>\n
    • be non-allergenic, for the well-being of human skin.<\/li>\n<\/ul>\n

      Nickel is a good alloying element. It imparts a pleasant green color and good strength. It also takes polishing well, preventing the edges from wearing off. A small percentage of people experience allergies to it (2.3%). Green gold casts fairly well and can be engraved, but not with every alloying element. For example, combining gold with rubidium, potassium, and indium produces a very beautiful alloy, but it is brittle and lacks sufficient ductility.<\/p>\n

      Gold is used in jewelry. The soft green color of the jewelry retains its natural vibrancy and adds a fresh look.. <\/strong>Such items include rings, bracelets, chains, brooches, pendants, and cufflinks. Green gold combines with various alloys, adding a distinctive style and enhancing a jewelry interior.<\/p>\n
