Making jewelry alloy can be compared to culinary art. Like any dish, it is painstakingly prepared and, in addition to gold, consists of various ingredients. The admixtures interact differently in the alloy and give the gold a particular shade.
Adding more of any one element can darken the alloy or make it brittle. In the process, it is important to ensure that the gold not only acquires the desired color, but also remains suitable for jewelry work. For example, a green hue is obtained when silver is added to the alloy, and pink and red when copper is added. You can consider different options here https://luxurydiamonds.ca/.
Copper causes bracelets, rings and other jewelry to have a reddish hue. The more copper in the alloy, the redder the color will be. With more than 14% copper, the hue of the alloy becomes bright red. On the other hand, if copper is added in small quantities, the result will be rose gold. If, on the other hand, you add a little copper, the result will be rosy red gold. Jewelers value red gold for its durability, which allows you to create airy, openwork jewelry without fear of deformation. Red gold is most often used in jewelry without inserts, sometimes with semi-precious stones. However, because of its high copper content, such gold pieces are more susceptible to oxidation.
White gold is now at the peak of popularity. Admirers of elegant luxury believe that it is the best way to enhance the elegance of the jewelry, effectively highlighting the precious stones. This white alloy contains up to 4% zinc, between 6% and 20% nickel, with the rest being copper. Platinum purely tints the gold in white. However, a product made of such an alloy will be an order of magnitude higher in cost. The most budgetary alloy of white gold contains nickel, zinc and copper.
In addition to gold, this alloy contains a high percentage of nickel, copper, and zinc. Because of this, the yellow metal loses its brightness and acquires a faint grayish hue. It should be borne in mind that the color of the alloy is prone to fading. Over time, the surface of the metal may show greenish castings. This alloy has good hardness and high casting properties.
Copper and silver (1:2 proportion) can be added to produce a warmer tone. For a richer shade, silver and copper are taken in equal proportions. Yellow metal has a wide range of colors – from pale yellow to red through greenish or reddish tones. The alloy becomes paler as the silver in it increases.
