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.

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.

Goldstone is a type of man-made glass with Copper or Copper salts made by a reducing flame. The most common form of Goldstone give the illusion of being a reddish-brown, although in fact the color comes from the Copper crystals and the glass itself is colorless. Other variants have an intensely color matrix usually blue or violet, and more rare, green.

Calcite is a Carbonate mineral that is most widely distributed on the Earth's surface.  It is a common constituent of sedimentary rocks with Limestone in particular.  A Calcite formation can take on many different shapes and sizes which is dependent on the location, ground water occurrence and temperature.  Calcite is usually white or colorless but can be gray, red, yellow, green, blue, violet, brown or black.  The deeper the color is usually indicative of the definitive impurities from the earth or water.

Septarians are commonly composed of a carbonate mineral such as Calcite, a microcrystalline form of Silica as in Flint or Jasper, or an Iron Oxide such as Hematite.  These specimens are also known as a concretion which is a type of sedimentary rock.   Septarians were formed millions of years ago by sediment forming around a fossil to create a mud ball transforming the fossil into Calcite and Aragonite.

Petrified Wood is a type of a fossil as it consists of fossil wood where all the organic materials have been replaced with minerals while retaining the original structure of the wood.  These minerals are most often Silicates such as Quartz.  Other minerals, Manganese, Iron and Copper, in the water or mud during the petrification process give Petrified Wood a variety of color ranges: black - Carbon; green/blue - Copper; red/brown/yellow - Iron.  Petrified Wood can preserve the original structure of the wood in all its detail all the way down to the microscopic level.  Structures such as tree rings and the various tissues are often observed features.  Although Petrified Wood can be found worldwide, it is rather rare in larger quantities and at times can be difficult to obtain by the average collector.

Opal is a colorful mineral of hydrated form of Silica related to Quartz. It's internal structure makes it diffract light, taking on many colors depending on the conditions when it was formed. Those colors can range from clear through white, red, orange, yellow, green, blue, purple, rose, pink, brown and black. Opal varies in optical density from opaque to semi-transparent. Opal is the national gemstone of Australia, a producer of over 93% of the world's supply.

Moonstone is a typical Potassium Aluminum Silicate with several commonalities with the Feldspar family.  It's name is derived from the visual effect or sheen that is caused by light reflecting internally and externally from the layer inclusions of different Feldspars.  Moonstone is closely related to Sunstone, Labradorite and Sodalite.

Selenite is a Crystalline variety of Gypsum.  It is often transparent and colorless.  If the Selenite Crystals show translucency, opacity and/or color, it is caused by the presence of other minerals and many be "druzy".  Selenite often appears to have a "cat's eye" appearance especially with the polished variety.  It will often magnify images when the translucency is very clear.
