Quartz is the second most common mineral in the Earth's continental crust.  It is mainly composed of Silica or Silica based minerals.  Although Quartz is known by a variety of names, the most important distinction between types of Quartz is that of macro-crystalline, individual crystals visible to the unaided eye, and micro-crystalline, where aggregates of crystals are only visible under high magnification.  There are many forms of Quartz including Chalcedony, Amethyst, Citrine, and Carnelian which are results of mineral impurities or heat treatments.

Obsidian is a type of naturally-occurring glass formed as an extrusive igneous rock.  It is produced when felsic lava erupted from a volcano, cools rapidly through the glass transition temperature and freezes without sufficient time for Crystal growth.  Because of the lack of Crystal structure, Obsidian blade edges can reach almost molecular thinness, leading to its ancient use of projectile points (arrow heads), and its modern use as surgical scalpel blades.

Marble is a metamorphic rock consisting of Limestone but composed mostly of Calcite.  It is used extensively for sculpture, building materials and has many decorative uses.  The pure white Marble is probably the most common form known, but the characteristic swirls and veins of many colored Marble varieties are usually due to various mineral impurities such as Clay, Silt, Sand, Iron Oxides or Chert.  This type of Marble will often have small animal like creature fossils throughout the matrix or media.

Zoisite is a Calcium Aluminum Silicate that belongs to the Epidote group of minerals.  When it is found transparent, it is formed in to gemstones while translucent-to-opaque material is usually carved into sculptural works.  The latter sometimes has Ruby Crystals which are completely opaque and unsuitable as gemstones, but are well colored and contrast strikingly against the green matrix of the Zoisite.  Zoisite may be green, blue, brown, pink, yellow, gray or colorless.

Amethyst is a purple variety of Quartz often used as an ornament.  Upon exposure to heat, Amethyst generally becomes yellow, which some refer to as Citrine or "burnt" Amethyst.  It occurs in color from a light, slightly pinkish violet to a deep grape purple.  It is widely distributed as a mineral, but fine, clear specimens that are suitable for cutting as ornamental stones.
