Onyx is a banded variety of Calcite.  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.  This type is found in Mexico and Pakistan and is often carved and polished into various items.  This material is much more readily available and softer than the gemstone commonly called Black Onyx which is a silica gem.

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.

Rutile is a mineral composed primarily of Titanium Dioxide. Rutile has among the highest refractive indices of any known mineral and also exhibits high dispersion. Rutile is known to contain up to 10% Iron as well as significant amounts of Niobium and Tantalum. Rutile creates small needles within crystals that can be seen when held up to light.

True Citrine is often rarer but is hard to distinguish from the heat treated variety. It is widely distributed as a mineral, but fine, clear specimens that are suitable for cutting as ornamental stones.

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. 3/4"

The Ocean Jasper deposit, even though it was found only a few years ago, is nearly gone and the material is becoming hard to find.  The deposit formed as a Rhyolite flow but has been completely silicified. The Rhyolitic eyes or orbs come in an astonishing array of colors and color combinations. The back ground can be white, pink, green, red, or yellow. Botryoidal formations as well as white and deep green druzy are also common. This deposit was discovered at the edge of the ocean. It can only be seen and collected at low tide. The area has no road so the material must be transported to civilization by boat.  Several other types of jasper are found in that area now but the orbicular Jasper is gone.

Peacock Marble is from Southwest China and formed in Limestone by heat and pressure in the earth's crust. Recrystallization during Himalaya formation caused the limestone to change in texture and makeup. Fossilized materials along with it's original carbonate minerals, recrystallized and formed large, coarse grains of calcite. Impurities present in the limestone during the recrystallization affected the mineral composition of the marble.  The minerals that result from the impurities give the marble up to ten different colors. The corresponding colors and minerals that can be found: Green - Serpentine; Purple - Manganese spar; Brown - Iron; Gray - Silicon Dioxide; Red - Hematite; Orange - Iron; White - Calcite; Violet - Iron Manganese; Yellow - Limonite; Blue - Copper, Cobalt, Chromium; Black - Carbon, Iron, Manganese. Peacock Marble is also called "seven color Jade" in local language.

Dendrites are branched or tree like inclusions, usually manganese or iron oxides that are caused by irreversible aggregation of small particles forming large cluster. It has only been in recent years that researchers have begun to understand how dendrites form and these ideas were developed by chemists and mathematicians working in disciplines called chaos and fractal geometry. Colloidal-sized particles move in random paths in a phenomenon called Brownian motion.

Lapis is a rock and not a mineral because it is made up from various other minerals. To be a mineral it would have one constituent only, and Lapis has several including Lazurite, Sodium, Aluminum, Silicon, Oxygen, Sulfur and Chlorine. Most Lapis contains Calcite, Sodalite and Pyrite. The best color is an intense blue that is lightly dusted with small flecks of Pyrite. Lapis takes an excellent polish and has been made into jewelry, carvings, boxes, mosaics and ornamental objects.

Fluorite, also known as fluor-spar, is a mineral composed of Calcium Fluoride.  It is a widely occurring mineral and is often found with metallic minerals such as Galena and Sphalerite, but also with Barite, Quartz and Calcite.  It may fluoresce strongly in ultraviolet light.  Although blue is the most common color, it can also be red, purple, green, yellow and white.
