Quality Indian Zeolite Assortment

Ref: ZeolMix

Stunning value mix owing to bulk import by us direct from India. Suitable as an amazing addition to any enthusiasts collection but also offered at such a low price that they present an opportunity for re-sale.

We have carefully chosen a collectors assortment of high quality crystalline zeolite specimens from India.
Each box will contain at least one specimen each of the majority of the more widely recognised types but by the very nature of these specimens there are likely to be more unusual crystals nestling amongst the varied clusters.
Usually included are Stilbite (pink 'sheaves'), Apophylite (clear cubic crystals with pyramid terminations), Prehnite (pale green), Gyrolite (green spheroids), Calcite (clear or brown), Heulandite (Pink or white Diamond-shaped 'fan') and Okenite (fragile white crystalline 'puff-ball'). Many of these attractive specimens will have more than one type of zeolite present on the piece. Collection weight on average 2.7Kgs and 15-20 specimens per box (Box measures 40cms x 20cms x 10cms).

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.

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.

2. CITRINE D-Term Xtl. Pt. 3-6cms (Ref: 23-618)

Meteorite. Campo Del Cielo, Argentina. Large

Ref: MeteorCDC

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 but some smaller pieces from the same 'shower' location occassionally come on the market and this is one of them.
Average weight is 200gms and measures 4-6cms. (Illustration is a guide to the average appearance.)

METEORITE Sikhote-Alin Fragment (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.
