Gold is a mineral, highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties. No other element has more uses than gold. All of these factors help support a price of gold that is higher than all but a few other metals. Traces of gold are found almost everywhere but large deposits are found in only a few locations.
They occur in hydrothermal veins deposited by ascending solutions, as disseminated particles through some sulfide deposits, and in placer deposits.
The most obvious physical property of gold is its color. It is one of just a few minerals whose names are used frequently in common language as the name of a color. The color is not altered by tarnish or the development of an oxidized surface. However, the color of gold varies with its composition. The color of gold is not constant.


Copper is one of the most important metals for the modern industry and, therefore, one of the businesses in which Prudent Builders Company operates. Its thermal energy conductive property surpasses that of any other commercially exploited metal. Malleable, recyclable, and resistant to corrosion and high temperatures, copper is used in the generation and transmission of energy, in wiring and almost all electronic equipment – such as TVs and mobile phones.



Diamonds is a composition of one single element. They are unique minerals that are made up of pure crystalline structures from the element carbon. Diamonds are created under immense heat and pressure deep below the Earth’s surface which contributes to the sparkle and shine of the mineral. Since they are only composed of carbon, diamonds are considered allotropes which are different structures created from the same single chemical element.
