Whois & Analysis for slateandtell.com

Jewellery or jewelry consists of small decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, and bracelets.

Jewellery may be attached to the body or the clothes, and the term is restricted to durable ornaments, excluding flowers for example.

For many centuries metal, often combined with gemstones, has been the normal material for jewellery, but other materials such as shells and other plant materials may be used.

It is one of the oldest type of archaeological artefact – with 100,000-year-old beads made from Nassarius shells thought to be the oldest known jewellery.

The basic forms of jewellery vary between cultures but are often extremely long-lived; in European cultures the most common forms of jewellery listed above have persisted since ancient times, while other forms such as adornments for the nose or ankle, important in other cultures, are much less common.

Historically, the most widespread influence on jewellery in terms of design and style have come from Asia.

Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it.

The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called engravings.

Wood engraving is a form of relief printing and is not covered in this article.

Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism.

It is the finest grained foliated metamorphic rock.

Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression.

Gold is a chemical element with symbol Au (from) and atomic number 79.

In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.

Chemically, gold is a transition metal and a group 11 element.

It is one of the least reactive chemical elements and is solid under standard conditions.

Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits.

It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium.

Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Silver is a metallic element with symbol Ag and atomic number 47.

The symbol Ag stems from Latin, derived from the Greek ὰργὀς (literally "shiny" or "white"), and ultimately from a Proto-Indo-European language root reconstructed as *h2erǵ-, "grey" or "shining".

A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.

The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.

Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

Silver is more abundant than gold, but it is much less abundant as a native metal.

Its purity is typically measured on a per mille basis; a 94%-pure alloy is described as "0.940 fine".
