4 x 1 x 5cm Tiger's eye is a semiprecious stone that is formed when parallel veins of crocidolite fibers are first altered to iron oxides and then replaced by silica. As a result it is more opaque, and creates a rich yellow to brown color. Tiger Eye can be found in Australia, Burma, United States, Brazil, China, and many other countries. ***Due to natural variations in stones, the appearance will vary***

4 x 3 x 20cm Sodalite is a rare mineral formed inside igneous rocks crystalized as a result of sodium-rich magma. The blue color comes from the rock that Sodalite is formed in; nepheline syenite, trachyte, and phonolite. Although the sodalite-bearing rock is rare, it can most commonly be found in the US, Canada, and Africa. ***Due to natural variations in stones, the appearance will vary***

8 x 2 x 8cm Septarian concretions are concretions containing cavities or cracks, called septaria. The septaria are the calcite (yellow) filled cracks at the center of the rock, indicating where the center of the concretions have shrunk, possibly during dehydration during its transformative journey over a long period of time. Septarian can be found mostly in the Gulf of Mexico and Madagascar. ***Due to natural variations in stones, appearance will vary***

4 x 1 x 4cm Sardonyx combines alternating layers of sard and onyx to create a reddish zebra-striped gemstone with white bands. Onyx is a banded variety of the oxide mineral chalcedony. Onyx and Agate are similar in that they are both varieties of layered chalcedony. The difference between the two is that agate has curved banding and onyx has parallel banding. The colors of the banding range from virtually every color possibility.Onyx is mainly found in Brazil, India, Madagascar, Mexico, Peru, and USA. ***Due to natural variations in stones, appearance will vary***

4 x 1 x 5cm Zoisite is a mineral that forms during the metamorphism and hydrothermal alteration of igneous, metamorphic, and sedimentary rocks. Anyolite is a very colorful rock composed mainly of zoisite. It is also known as "ruby in zoisite" because it is composed of green zoisite with bright red ruby. Rubies are corundum gems that are predominately red. The color can range from orangish red to purplish red. The most desirable color range is a pure vibrant red to a slightly purplish red. Ruby in Zoisite was discovered and is still only found in Tanzania ***Due to natural variations in stones, appearance will vary***

8 x 2 x 7cm Rose Quartz is an anhedral crystal. It is found in the cores of pegmatites and gets its color from microscopic inclusions of a pink variety of the mineral dumortierite . Rose Quartz is naturally a pink hue but can have more hues of grey/purple or red. This mineral Earth's can be found in many places including South Africa, Madagascar, and Brazil. ***Due to natural variations in stones, the appearance will vary***

4 x 4 x 5cm Agate is a translucent form of microcrystalline quartz. These crystals form inside of igneous rocks over a long period of time and get their banding from years of siliceous groundwater building up in the cavities of these rocks. What makes this mineral so beautiful and unique is that the color variations and banding patterns are completely dependent on the environmental factors around them. This makes it so that every formation is different and there are no two formations that are the same! ***Due to natural variations in stones, the appearance will vary***

2 x 1 x 7cm Fluorite is composed of fluorine and calcium and is formed in hydrothermal veins in the Earth's crust. This mineral can be found in all colors of the rainbow with different hues. The different colors in Fluorite are caused by impurities within the mineral. The deeper colors are found in well-formed crystals. Fluorite was originally discovered in Illinois in 1842 but is no longer mined in the US. It can be found in China, South Africa, Mongolia, France, and Russia. ***Due to natural variations in stones, the appearance will vary***

4 x 1 x 5cm Aventurine is a part of the quartz family. This mineral ranges many colors; pink being the most rare of all the colors. This mineral is composed of quartz with many micro inclusions (such as mica) to create its beautiful appearance. The pink tone in it comes from the hematite in the mineral. This mineral is most commonly found in India but can also be found in Brazil, Austria, Canada, and Tanzania. ***Due to natural variations in stones, the appearance will vary***

8 x 3 x 8cm Green Opal is a type of common opal that ranges in color from a pale to dark green. It's one of the easiest Opals to find and can be found in 6 continents. Most of these specimens have come from Australia, Brazil, USA, Mexico, and Peru. ***Due to natural variations in stones, the appearance will vary***

4 x 1 x 5cm Hematite is a heavy and relatively hard oxide mineral. It is made of ferric oxide. It constitutes the most important iron ore because of its high iron content (approximately 70 percent) and its abundance. Its name comes from its Greek meaning, "blood". Hematite is unusual in that its macrocrystalline forms are incongruent, while its particulate forms are congruent. When it is formed congruently, it has a red color to it and when formed incongruently, it is a silvery-black color. ***Due to natural variations in stones, the appearance will vary***
