Native Copper specimen ~3cms. Michigan USA

Ref: Copper

Two kinds of copper ore are commonly mined: chalcopyrite and bornite: occasionally the metal is found in it's pure or 'native' state like this specimen. Copper ore is found throughout the world and Zaire is renowned as a source, but the low percentage of metal obtained from the ore and the often hard-to-access location of deposits make many potential mines uneconomic.
Copper is the second most-used metal in the world and is valued for its conductivity (for electrical cable) malleability, resistance to corrosion, and beauty. Copper was mined in Cheshire (Alderley Edge) and in Anglesey (Parys Mountain) before the turn of the century.
As these are natural (cleaned) specimens each will vary from the illustration but be similar in size (approx 3cms).

Specular Hematite with Rutile

Ref: SpecHemRut

A black or grey variety of hematite with brilliant metallic luster, occurring in micaceous or foliated masses, or in tabular or disk-like crystals. Also known as grey hematite; iron glance; specular iron.
TiO2, Titanium Oxide. Rutile is an ore of titanium, used for high tech alloys due to it being light weight, high strength and resistance to corrosion. Rutile is also very popular in the gemstone markets as it forms beautiful specimens when included in clear quartz and is known as 'venus-hair stone'. This specimen of Specular Hematite has radiating needles of gold Rutile crystals growing epitaxially. Average specimen size 2cms - appearance will vary from that illustrated as these are all natural specimens.

Single Herkimer-type Quartz Crystal from Morocco

Ref: QtzHerkTypeLge

Quartz, which is the most abundant silica mineral and which occurs in most igneous and practically all metamorphic and sedimentary rocks, is nearly pure silicon dioxide. The name quartz is believed to have originated in the early 1500s from the Saxon word querklufterz (cross-vein ore), which was corrupted to quererz and then to quartz. Quartz was well known to the ancients, who called it crystal or ROCK CRYSTAL.
Quartz is colorless and transparent when pure. Its hardness is 7 on the Mohs scale. This crystal exhibits clarity with natural smooth faces in a double-terminated configuration and similar crystals from Herkimer County in New York are prized by collectors throughout the world.
Crystal supplied will have an average dimension of 2cms. and will be supplied mounted on a descriptive card.

BISMUTH Lab-grown Xtl. Carded 1-2cms

Ref: 23-709

Bismuth is the most diamagnetic of all metals (i.e.,opposition to being magnetized) It is hard, brittle, lustrous, and coarsely crystalline. Bismuth is frequently associated with ores of tin, lead, or copper . It expands slightly upon solidifying, rendering bismuth alloys particularly suited to the manufacture of sharply detailed metal castings. With a low melting point, Bismuth alloys are used in special solders as well as in automatic sprinkler heads, fire-door release lines, fuses, safety plugs for compressed-gas cylinders, and many other fire-detection devices. The oxychloride BiOCl has been used to impart a pearlescent quality to lipstick, nail polish, and eye shadow.

Pyrope Garnet crystal. Approx 2cms China (carded)

Ref: GarnPyrop

This magnesium-aluminium silicate Garnet crystal is a very dark (almost black) example of red Pyrope (name from the Greek for fire and eye). Crystals are in the shape of a rhombic dodecahedron with a high specific gravity.
Crystals are found in metamorphosed limestone and sometimes in igneous rocks and may also be of the Almandine variety. Varieties are sometimes found in serpentine rock along with asbestos, mica and olivine. Main locations are The Soviet Union and the USA but it is also found in Norway and Germany - and more recently supplies are coming from China.
Garnet is the BIRTHSTONE for January and is thought to originate from the the Latin owing to a similarity to Pomegranate seeds.
Specimen is supplied on a descriptive card.

Octahedral cleaved 2cms Green Fluorite Crystal from China

Ref: FluorOctGreen

FLUORITE -also called FLUORSPAR, common halide mineral, calcium fluoride (CaF2). Fluorite occurs most commonly as a glassy, many-hued vein mineral and is often associated with lead and silver ores; it also occurs in cavities, in sedimentary rocks, in pegmatites, and in hot-springs areas. It is widespread throughout the world. Fluorite is used, amongst other things, as a flux in the manufacture of open-hearth steel. In the nineteenth century 'Blue John', a variety from Derbyshire, England, was widely used in ornamental vases and other objects. Colour and size will vary slightly as this is natural material but they will be a shade of green and approximately 2cms overall.

TEKTITE (Hunan China) Average 4cms (Carded)

Ref: 23-890

This tektite was said to be from Hunan, an inland province in southeast China, situated adjacent (north and northwest of) Guangdong. Tektites appear to be glassy bodies formed from sediments melted during large terrestrial impact events. Many but not all exhibit tubular to button-shaped forms, often with tiny surface ridges or bubbles, the overall shape consistent with a glass cooling and solidifying during its brief atmospheric passage during “re-entry”. Because they are largely glass, possible sources of mistaken identity include glassy volcanic rocks (e.g., obsidian), slags and other industrial by-products, and waterworn bottle glass recovered on beaches.

MAGNETITE crystals (4-9mm) in tub (avge 60pcs)

Ref: 23-817

Magnetite is one of the most widespread and abundant minerals and an important ore of iron. An OXIDE MINERAL, it crystalizes in the isometric system forming iron-black octahedral and dodecahedral crystals, as well as granular or laminated masses.
The naturally magnetic variety, lodestone, was well known to the ancient Greeks. Hardness is 5.5-6.5. Often formed at high temperature, magnetite is a common constituent of crystalline rocks, forming abundant grains in ferromagnesian igneous rocks and disseminated crystals in metamorphic rocks. It also occurs in beach sand, in meteorites, and in the natural abrasive EMERY.
The world’s largest deposits are in northern Sweden. The most powerfully magnetic material occurs in the Harz mountains, in Siberia, and on the island Elba.

Iron Pyrite Crystal on matrix 23-854

Ref: PyriteMatrix

A well defined, natural (unpolished), crystal from a classic collectors location in Navajun, Spain.
Iron Pyrite is sometimes called 'Fools Gold' due to its metallic gold sheen appearance but gold is not found in such precise crystal form and usually has a deeper yellow colour and is much more dense.
As these are natural specimens they will vary from that illustrated but will generally have at least one cubic crystal of about the size chosen.
We also supply loose single crystals of various sizes - see below in this section.

METEORITE Sikhote-Alin Fragment 2-3cms (Carded)

Ref: 23-822

This (Iron-Nickel) Meteorite is known as a 'fragment'. The original Sikhote-Alin 'shower' happened in Russia at 10.30 a.m. on the 12th February 1947 and is the largest known such fall and well documented. It is now estimated that over 100 tons of postatmospheric mass hit our planet at about 14.5Km/second. To date, it is believed that about 30 tons have been collected - the largest weighing 1,745Kg and the smallest less than a gram!
These 'fragments' litter the strew field and are the result of relatively large-mass objects shattering on impact with frozen ground.
Each specimen (will vary from that illustrated) measures about 2-3cms and is supplied on a descriptive card with the above information.

METEORITE Campo del Cielo fragment ~1cms (Carded)

Ref: 23-824

Originally discovered in 1576 but thought to have fallen about 4000-6000 years ago. The ancient Indian name means 'Field of the sky or heaven'.
The meteorite is predominently Iron with 6.62% Nickel. It is a course Octahedrite with silicate inclusions.
In the 1770's a mass weighing about 14-18 tons was discovered and thought to be the original 'Meson de Fierro' named by the Spanish in 1576, but it was not excavated. There is speculation that the same mass was in the news in 1992 when an American Meteorite dealer negotiated a private purchase but was arrested by the Argentinian authorities when he tried to transport it. The mass remains in Argentina.
This fragment has been taken from a larger piece and tumble-cleaned. Average 1cms

Quartz is colorless and transparent when pure. Its hardness is 7 on the Mohs scale.Coloured varieties are numerous and popular. Amethyst (violet); smoky quartz; cairngorm, or morion (black); citrine (yellow); and rose quartz are common and arise by the incorporation of a tiny fraction of elements that substitute for silicon atoms, such as iron, aluminum, manganese, and titanium.
