Rhyolite is an igneous, volcanic rock that is composed of Felsic, or Silicate minerals such as Silica, Aluminum, Sodium and Potassium.  The material is similar to that of Granite, Pumice and Obsidian but due to the cooling process when formed, Rhyolite did not form any crystals, thus changing the texture of the material.

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.

Rose Quartz is a type of Quartz which exhibits a pale pink to a rose red hue.  The color is usually due to its trace amounts of Titanium, Iron or Manganese.  Sometimes it will contain microscopic Rutile needles which produce an asterism in transmitted light.  It is rarely found in Crystal form.  It is not very popular as a faceted gem because the stones are always cloudy, the pink color is often too pale and most Rose Quartz gems have large flaws.

Onyx is a banded variety of Chalcedony which in turn is a form of Quartz.  The colors of its bands range from white to almost every color except shades of purple, blue and black.  It is used for vases, bowls, beads, cabochons and other items.  The name has sometimes been used incorrectly to label other banded lapidary materials, such as banded Calcite.  This type is found in Mexico and Pakistan and is often carved, polished and sold.  The material is much softer than true Onyx and much more readily available.

Marble is a metamorphic rock consisting of Limestone but mostly composed of Calcite.  It is used extensively for sculpture, building material 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.

Marble is a metamorphic rock resulting from the recrystallization of pre-existing rocks due to changes in heat and/or pressure and/or introduction of fluids without melting.  It is composed mostly of Limestone and Calcite.  Marble is used extensively for sculpture, building materials and other applications.  Picasso Marble is found in Utah and is identifiable by its striking and dramatic combination of browns, blacks, grays and white colors and each piece is uniquely different.
