Is titanium more expensive than gold
The Jewelry metals: gold, silver, platinum and titanium
A gemstone can shine in many different colors and thus delight. For thousands of years these precious natural treasures have been set in precious metal in order to be able to adorn themselves with them. Precious metals can not only be an appropriate framework for a precious stone, but also offer protection to the valuable asset at the same time.
Gold is the most common material used in jewelry making. It is still very popular today, and was at times even considered the most valuable of all precious metals, as it has a high economic value and is rare. This brilliant treasure was discovered around 3,000 BC. BC, but the first gold could be as early as 6,000 BC. In the Transylvanian Alps.
Its name goes back to the Old High German word "gold", which stood for "yellowish" or "blank". The chemical symbol "Au", on the other hand, refers to the Latin "aurum" ("gold"). In addition to its use as jewelry metal (and thus also as a symbol of wealth and special social status), gold has always been used as a means of payment, investment or commodity.
Of all precious metals, gold is best malleable, and pure gold retains its typical luster and shimmer, never tarnishes and is corrosion-resistant. Since pure gold is ultimately too soft for decorative applications, it is often alloyed with other metals to increase its durability.
The international measure for the purity of gold is the "carat", usually abbreviated with "K" (the unit of measurement for the weight of precious stones - "carat" - is abbreviated as "ct").
The respective gold content is given as the ratio of a total of 24 parts, with 24 K standing for pure gold. In Germany, on the other hand, it is customary to specify it in thousandths. The following degrees of purity are most commonly used for jewelry:
- 916: 91.6% pure gold (= 22 K: 22 parts gold and 2 parts alloy)
- 750: 75% pure gold (= 18 K: 18 parts gold and 6 parts alloy)
- 585: 58.5% pure gold (= 14 K: 14 parts gold and 10 parts alloy)
- 417er: 41.7% pure gold (= 10 K: 10 parts gold and 14 parts alloy)
- 375: 37.5% pure gold (= 9 K: 9 parts gold and 15 parts alloy)
Gold is available in different colors, which are created by the different alloy metals. The most popular are yellow, white and rose gold.
Yellow gold is alloyed with silver and copper and is found most frequently.
White gold is a modern gold variant that is created by bleaching yellow gold.
Rose gold is also known as "red gold" or "Russian gold" because this color has been popular in Russia since the beginning of the 19th century. It is alloyed with copper - the higher the copper content, the stronger the red color.
The silver extracted from ores such as argentite has a history that goes back more than 5,000 years. As a popular and affordable choice in jewelry, it finds application in almost every culture. In addition, silver is also used in the manufacture of art objects, such as silver cutlery and silver tableware.
The chemical symbol for silver is “Ag”, derived from the Latin word for silver, “argentum”. Our current name is derived from the Old High German "sil (a) bar".
The relatively easily malleable pure silver is softer than gold or platinum. Silver is usually alloyed with secondary metals such as copper to give it more strength. As with platinum, the purity of silver is given as a percentage of 1,000 parts. Sterling or 925 silver is 92.5% pure and is considered the standard for quality silver jewelry. Sterling silver has 75 parts (7.5%) of alloy for every 1,000 parts. The 95.8% pure Britannia or 958 silver is also very common.
As a rule, gold is considered the most precious jewelry metal, although platinum (Pt) is sixty times less common. It is also purer, more stable and denser than gold. The naturally white platinum is particularly suitable for jewelry processing due to its durability. In addition, platinum is hypoallergenic, so it hardly causes any allergic reactions. The purity of platinum is given in proportions of 1,000 parts. The most common purity grades are 950 (95% pure), 900 (90% pure) and 850 (85% pure) platinum.
It was first described by Julius Caesar Scaliger (1484-1558) and got its name from the Spanish word "platina", which means something like "little silver" and refers to the visual similarity to silver. Platinum was extremely popular under France's Sun King Louis XIV, who declared it the only metal worthy of a king. However, since it was declared a vital metal during World War II, it has never regained its former popularity.
The use of titanium as a jewelry metal has a shorter tradition. Today it is valued by many for its lightness and resilience, and is also characterized by its special color and the silky, shiny surface. Allergy sufferers also prefer titanium because it is hypoallergenic and nickel-free.
