This diagram shows some examples of the composition of various gold caricatures. Platinum, a naturally white metal, is usually used in an almost pure form for jewelry – from 95 to 98%. Platinum is almost identical to white gold and will be the same for many years to come, as long as they are both maintained and maintained. As you can see from their carat numbers, 10-carat, 14-carat, and 18-carat white gold differ from each other in terms of the amount of gold they contain: green gold was already available to the ancient Persians in 860 BC. Known as Electrum, a natural alloy of silver and gold. [3] It actually appears greenish-yellow rather than greenish-green. Baked varnishes adhere better to these alloys than to pure gold. Cadmium can also be added to gold alloys to create a green color, but its use raises health concerns because cadmium is highly toxic. [8] The alloy of 75% gold, 15% silver, 6% copper and 4% cadmium gives a dark green alloy. Given this brief introduction to gold, its purity and its mixtures with other metals, 14-carat and 18-carat white gold accumulates: “karatage” is the measure of the purity of gold alloyed with other metals. 24 carats is pure gold without other metals.
Lower karates contain less gold; 18-carat gold contains 75% gold and 25% other metals, often copper or silver. The cost of white gold and yellow gold is relatively the same, as they are both made of gold and other alloy metals. 14-carat gold costs less than 18-carat gold, regardless of color. Hello gemstone, good question. As a rule, we never perform destructive tests. Most precious metal parts can be determined without damaging the part. However, if there is a suspicion that a piece may be gold plated or gold plated, a small scratch may need to be applied to a discreet part of the jewel. But that`s not the norm, and we`d always let you decide if you want us to do this test before you do it. Do you want to see real jewelry in these different metals? You can always come to our shop to personally touch and see the differences. Or you can check out some platinum and white gold products available online here. The amount of pure gold in jewelry depends on its karatage: Hello. I wondered, how do you tell the difference between gold and silver? Over the past half century, white gold has become more popular than yellow gold.
This is a testament to its contemporary and versatile look, exceptional value and high quality. Purple gold (also called amethyst gold and purple gold) is an alloy of gold and aluminum rich in gold-aluminum intermetal (AuAl2). The gold content of AuAl2 is about 79% and can therefore be described as 18-carat gold. Purple gold is more fragile than other gold alloys (a serious flaw when formed in electronics[11]) because it is an intermetallic compound instead of a malleable alloy and a violent blow can cause it to break. [12] It is therefore generally treated and faceted to be used as a “gemstone” in conventional jewelry and not by itself. With a lower gold content, the material is composed of the intermetallic solution phase and an aluminum-rich solid solution phase. At a higher gold content, gold-rich intermetallic AuAl is formed; The purple color is kept at about 15% aluminum. At 88% gold, the material is made of AuAl and changes color. The actual composition of AuAl2 is closer to Al11Au6 because the subnet is incompletely occupied. [2] Rose gold is made of pure gold mixed with copper and silver alloys. Rose gold is real, but it`s not entirely made of gold. Copper and silver help to strengthen it and give it its pink color.
The more copper is used, the more red gold appears. A common mixture – or alloy – for rose gold is 75% gold and 25% copper by mass (18K). Like white gold, rose gold is an alloy, so “pure rose gold” for jewelry does not exist. As you might expect, the price of white gold varies depending on its purity. In general, the more gold a jewel contains, the more expensive it is. Continuing our previous blog post, in which we compared 14,000 and 18,000 rose gold, we now want to compare the difference between 14k and 18k white gold.

[2] White gold is a mixture of pure gold and white metals such as nickel, silver and palladium, usually with a rhodium coating. White gold is real, but it is not entirely made of gold. Other metals help strengthen gold and increase its durability for jewelry. The value of white gold depends on the carat (14K vs 18K) and the amount of metal used to make the ring.

A blue gold surface coating on carat gold or sterling silver can be obtained by gilding the surface, followed by an indium coating, with the thickness of the layer corresponding to the atomic ratio of 1:2. The heat treatment then causes the interdiffusion of the metals and the formation of the required intermetallic compound.
