Alabaster: The alabaster is a name applied to the varieties of two distinct minerals: gypsum and calcite; alabaster found today would rather gypsum. If the gypsum is white, was created by calcite deposit stalagmitic; the latter is formed by deposition in successive layers sometimes mixed with other elements (such as iron oxide or sulfur) which gives him the appearance of the marble or onyx, mixed colors (white, black, pink, yellow). To reduce the translucency of alabaster and produce an opacity suggestive of marble statues are immersed in a bath and heated gradually, an operation requiring great care. If treated properly, it will look very closely at the real marble.
The Egyptian alabaster has been intensively worked near Suez and Assiut, there are many ancient quarries in the hills overlooking the plain of El Amarna. The black alabaster is a rare form found only in Oklahoma (USA), Italy, and China. Its base is marble. Gender finest alabaster are largely used as ornamental stone. Several varieties are identified - veined, spotted, opacifié, agatiform. The alabaster of the Bible, often called oriental alabaster, at its dù from the Far East. This alabaster "oriental" is strongly suggested for making small perfume bottles, vases ointment, jars canopic, and other sacred objects and sépulcraux. The leaves are somewhat translucent alabaster to be used as small windows, they have been used and in medieval churches, particularly in Italy.
The objects sculpted alabaster are increasingly rare for the benefit of molding powder based alabaster.


Basalt: The basalt rock is volcanic extrusive black. It usually consists of a fine-grained to rapid cooling of the lava on the Earth's surface. The parties in the crust of oceanic tectonic plates are composed primarily of basalt, produced from the cable mantle below the ocean ridges.
"The black stone" is the volcanic rock, the most widespread thanks to his qualities of hardness and impermébilité; it is used both in the railway construction, in construction, and more recently in the production of statues in some countries.

Onyx: The Onyx is a form of cryptocrystalline quartz. The colors of the bands range from white to almost every color (except purple and blue). Sard-onyx is a variant in which the colored bands are sard (shades of red) rather than black. Although not rare, pure black onyx is the least common.
There are two forms of Onyx - Onyx chalcedonic and onyx limestone; the latter through its training stalamitique, has been mixed with other minerals and gave variations onyx (onyx-albâtre, onyx- marble).
The latter is widely used in ornament and jewelry especially in countries like Mexico or Pakistan. Originally the term "Onyx" means an Assyrian ring, and may relate to any stone used to make rings. They say that the Onyx banit punishment and brings wealth to the owner of it. It is also indicated to provide identifying personal strengths
