Mineral Collection

15 Stone Set

Our Mineral Colletion is not a run-of-the-mill pile of stones - we've included unique stones that are not usually found in sets at this price. Among the more usual stones in our collection we've included turquoise, emerald, tourmaline, star sapphire and a wonderful example of pyrite in its natural cube form! Each stone averages out at approximatly 1.25" long and are loose in their individual tray spaces. Most sets feature stones that are glued down, but ours are meant to be enjoyed from every angle! Pick 'em up and move 'em around to get a better look at every unique feature.

• Huebnerite (Czechoslovakia): contains a small amount of iron and is red/brown/black in color. It is a manganese member of the wolframite series and occurrs in short, monoclinic, prismatic crystals.
• Turquoise (Mexico): a blue/green mineral of copper & aluminum. Cut & polished turquoise is used as a gemstone.
• Emerald (Brazil):  flawless emeralds with good color are some of the most sought after precious gems (most emeralds are flawed & cloudy).
• Howlite (Zimbabwe): is white/gray with gray/black and is popular because it is easily died to immitate other minerals. Our specimin has been dies to resemble turquoise.
• Unakite (South Africa): is an altered type of granite and is made of pink orthoclase feldspar, green epidote and clear quartz.

• Lemon Chrysoprase (China): is a type chalcedony (fiberous quartz) that gets its color from nickel. Normally a bright apple-green - our sample is a pale lemon-yellow. 
• Tourmaline (Brazil): consists of varying amounts of aluminum, iron, magnesium, sodium, lithium, potassium, and other elements. Tourmaline is a type of gemstone that is sometimes used in electronic instrumentation.
• Copper (Michigan, USA): is one of the most basic elements. Combine it with zinc to make brass and combine it with tin to make bronze.
• Albite (Brazil): usually forms brittle glass-like crystals that may be white, yellow, pink, green, black or even colorless. It is often used to make ceramic & glass products.
• Red Jasper (South Africa): mainly brick/brownish red jasper has historically been used for ornamentation & jewelry. Black jasper, called a touchstone, has been used to test gold/silver alloys for their gold content.

• Amethyst (Uruguay): is a purple/violet form of quartz with high-quality amethyst being a deep purple. Heating amethyst causes it's color to change to yellow then brown and eventually removes all color.
• Tiger Eye (South Africa): is usually yellow/brown but gentle heating will produce a red/brown color. A rare bule variant is called Hawk's Eye.
• Star Sapphire (India): when viewed with a single overhead light, star sapphires can produce a six-rayed star-shaped pattern. The better the star-pattern the more valuable the star sapphire.
• Malachite (Kenya): is an important ore of copper. It is considered a gem and has been used in various ornamental purposes and also as a pigment.
• Pyrite (Spain): also known as "fools gold", pyrite is a source of sulfur and is used in the production of sulfuric acid.
