Natural Amber is an organic, time hardened fossilized resin material of vegetable origin. It came from a species of Pinus Succinisera (Pine) trees around 45 million years ago from the Baltic region of Europe. Amber is a soothing material that is both calming an energizing and said to bring clarity of thought and wisdom. Reconstituted Amber is made by melting pieces of natural Amber and allowing it to cool and return to a solid state. Real Amber is not available is large sizes suitable for making into spheres or other large polished items.

This awesome specimen measures 7 1/4" long x almost 3 1/2" x nearly 3 1/4" and has a smooth, natural finish.   Quartz crystals usually don't photograph well and this very nice example is no exception.  It does have some minor damage on the tip, common for this material and reflected in our price.  Just gorgeous!

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.

Agates mostly occur as nodules in volcanic rocks or waters containing Silica in solution which is possibly derived from the decomposition of Silicates in the lava.  The Siliceous matter is deposited in regular layers resulting in the banded or striped formation.  It is very unlikely that you would ever find an exact duplicate of any type of Agate, Brazilian or other.

Jasper, or spotted stone, is an opaque, impure variety of Quartz that is usually red, yellow or brown in color.  Some Jaspers simultaneously exhibit several variants such as banding, flow patterns, dendrites or color variations.  This results in what appears to be scenes or images in a cut section of the Jasper.

Moldavite is an olive-green or dull greenish vitreous substance possibly formed by a meteorite impact.  It is one kind of tektite found only in the Czech Republic. Moldavite is also known as the Grail Stone, as it is believed to have been the green stone in what is known as the Holy Grail.  During the Middle Ages, only those who were considered royalty or the highest nobility, wore jewelry fashioned out of moldavite.  Moldavite has historically been used in tool making, as well as being displayed in pendants and as heads of walking canes in Central Europe.

Tiger-eye is a member of the quartz family, a cryptocrystalline variety. It is one of the chatoyant varieties of gemstones. Due to the fibrous structure of the gemstone, as light reflects within the thin parallel fibrous bands it exhibits a changeable silky luster or chatoyancy. It occurs naturally in colors of gold and blue.

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.

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.

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.

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.

Geodes are geological rock formations which occur in sedimentary and certain volcanic rocks.  They are essentially rock cavities or vugs with internal Crystal formations or concentric banding.  The exterior is generally Limestone while the interior contains Quartz Crystals and/or Chalcedony deposits.  If the Geode is completely filled with Crystal, being solid all the way through, it is then called a nodule.
