Marcasite jewellery is jewellery made from pyrite (fool's gold), not, as the name suggests, from marcasite. Pyrite is similar to marcasite, but more stable and less brittle. Marcasite jewellery has been made since the time of the Ancient Greeks. It was particularly popular in the eighteenth century, the Victorian era and with Art Nouveau jewellery designers. It is frequently made by setting small pieces of pyrite into silver. Cheaper costume jewellery is made by glueing pieces of pyrite rather

Gembone is mineralized bone, often dinosaur bone, which has had the individual cells fossilized with precious minerals. It is one of three gemstones created from organisms (the others being Pearl and Ammolite). Many minerals can be found in Gembone including hematite, iron, pyrite, jasper, marcasite, agate, quartz or other crystal.

Lorandite is a thallium arsenic sulfosalt with the chemical formula: TlAsS2. Though rare, it is the most common thallium bearing mineral. Lorandite occurs in low temperature hydrothermal associations and in gold and mercury ore deposits. Associated minerals include stibnite, realgar, orpiment, cinnabar, vrbaite, greigite, marcasite, pyrite, tetrahedrite, antimonian sphalerite, arsenic and barite. The mineral is being used for detection of solar neutrino via a certain nuclear reaction involving

A sulfide mineral is a mineral containing sulfide (S) as the major anion. Sulfides are economically important as metal ores. The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts. Common or important examples include: Sulfides: Arsenides: Antimonides: Tellurides: Sulfarsenides: Sulfosalts:

For the igneous rock type websterite , see pyroxenite. Aluminite is a hydrous aluminium sulfate mineral with formula: Al2SO4(OH)4·7(H2O). It is an earthy white to gray white monoclinic mineral which almost never exhibits crystal form. It forms botryoidal to mammillary clay like masses. It is very soft Mohs hardness of 1 with a specific gravity of 1.66—1.7. It forms as an oxidation product of pyrite and marcasite along with aluminous silicates and clays. It was first described in 1807 from

Pseudofossils are inorganic objects, markings, or impressions that might be mistaken for fossils. Pseudofossils may be misleading, as some types of mineral deposits can mimic lifeforms by forming what appear to be highly detailed or organized structures. One common example is when manganese oxides crystallize with a characteristic treelike or dendritic pattern along a rock fracture. The formation of frost dendrites on a window is another common example of this crystal growth. Concretions are

A bracelet is an article of jewelry which is worn around the wrist. Bracelets can be manufactured from leather, cloth, hemp, plastic or metal, and sometimes contain rocks, wood, and/or shells. Bracelets are also used for medical and identification purposes, such as allergy bracelets and hospital patient identification tags. Although the term armlet may be technically similar, it is taken to mean an item that sits on the upper arm: an arm ring. The origin of the term 'bracelet' is from the Latin

Friendship bracelets are bracelets given from one friend to another as a symbol of friendship. They are handmade and usually made out of embroidery floss or thread. There are various styles and patterns, but most are based on the same simple half hitch knot. The making of friendship bracelets is a version of macrame. The amount of thread used in bracelets can and usually does vary. The smallest pattern, a double chain knot, requires two strings. The candy stripe can have as few as three strings

Broken Bracelet is the very rare debut album by American singer songwriter Michelle Branch, released by the independent record label Twin Dragon Records in 2000 (see 2000 in music). The record was recorded over two weeks in April 2000, and released on June 1, 2000 prior to her record deal with Maverick Records in December 2000. Four of the album's eleven tracks ( If Only She Knew , Sweet Misery , I'd Rather Be in Love , and Goodbye to You ) were later re recorded for inclusion on Branch's
