Scandium is a silvery metal that is soft and has a density of about three times that of water. Scandium is a transition metal and is also considered a rare earth element due to similar chemical properties (such as difficulty in extracting and in separating from other elements) and existence in the same ores, according to Chemicool.

Scandium is the 31st most abundant element on Earth, according to Periodic Table, with about 22 parts per million abundance by weight in Earth's crust, according to Chemicool.

Scandium is scattered thinly and has been found in over 800 minerals. Within these minerals, scandium is found in its oxide form (Sc2O3, also known as scandia or scandium oxide), according to Scandium Mining.
In the first attempt to isolate scandium, Nilson and his team processed 10 kilograms of euxenite and were able to produce about two grams of scandium oxide. According to the New World Encyclopedia, metallic scandium wasn't produced for the first time until 1937 by Werner Fischer, Karl Brünger, and Hans Grienseisen, German chemists. In 1960, 99 percent pure scandium was produced.

Most of the alloys in our catalog fall under the definition of master alloy and the question of what exactly is meant by this definition may arise.

An alloy is a compound made up of two or more elements, of which at least one is a metal. The characteristics of an alloy such as hardness, strength and even color are generally different from those of the elements that constitute it, for example copper and tin, both relatively soft, form the more resistant bronze.

With the evolution of technique, jewelry has required increasingly specialized performance from alloys, this has led to the need to study the use of new elements to be added to precious metals, which are able to drastically change their characteristics. So we went from having alloys composed of two or three elements, to new formulations that come to contain even 10, effectively increasing the complexity of the product.
