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.

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

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.

Citrine is any Quartz Crystal or cluster that is yellow or orange in color. Most Citrine, usually begins as Amethyst which becomes yellow due to heat treatments. 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.

Tourmaline is one of the most chemically complicated of all Silicate minerals. It is a complex Silicate of Aluminum and Boron and the composition varies widely with Sodium, Calcium, Iron, Magnesium, Lithium and many other elements that enter into it's structure. It can occur in a long, slender needle-like crystal to a thick prismatic and columnar crystal to a radial like daisy formation. It comes in many colors usually black and brown (iron rich); brown and yellow (magnesium rich); and blue, red, green, yellow, and pink (lithium rich). This mineral is found in igneous rocks, like Granite Pegmatite, and metamorphic rocks such as Schist and Marble.

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.

Malachite is a Copper Carbonate mineral that often forms botryoidal, fibrous or stalagmitic masses. It is often the result of the weathering of Copper Ores and is commonly found with Azurite, Goethite and Calcite. It is typically associated with Copper deposits including Limestone which is the source of the Carbonate. Malachite is found in many regions world wide and is usually shaded green in color.

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.
