Afghanite is strictly used as a rare collectors mineral. noteworthy localities Afghanite is a rare mineral, with the only significantly important deposit being Sar-e Sang, Kokcha Valley, in Badakshan Province, Afghanistan, where it forms large and beautiful crystals that are almost always embedded on a white marble matrix.

Traditional amber stone is a hard, golden-yellow to brownish-yellow translucent resin. In rare forms it can be blue or green. It is considered an organic gem, as it came from ancient tree resin.

Kyanite, sillimanite, tourmaline, chrysoberyl, chrysoberyl cat's eye and smoky quartz are the most popular stones similar in color to andalusite. Lesser Known Related Gemstones: Chiastolite (Cross Stone) is an opaque variety of andalusite. Sillimanite cat's eye is related to both kyanite and andalusite.

Chrysocolla has a cyan (blue-green) color and is a minor ore of copper, having a hardness of 2.5 to 7.0. It is of secondary origin and forms in the oxidation zones of copper ore bodies. Associated minerals are quartz, limonite, azurite, malachite, cuprite, and other secondary copper minerals.

Citrine is one of the most popular golden gemstones on the market today and it is very moderately priced even in large sizes. Since citrine is one of November's birthstones, it is highly sought-after for use in birthstone jewelry, especially birthstone rings and pendants.

Heliotrope, to some, might sound like some prehistoric animal but is, in actual fact, a gemstone found in quartz beds. This gem is also known as the Bloodstone and is the second birthstone for the month of March on the traditional birthstone listing.

Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe 2 O 3), one of several iron oxides. It is the oldest known [clarify] iron oxide mineral and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.

Kyanite is a typically blue silicate mineral, commonly found in aluminium-rich metamorphic pegmatites and/or sedimentary rock. Kyanite in metamorphic rocks generally indicates pressures higher than four kilobars.
Larimar, also called "Stefilia's Stone", is a rare blue variety of the silicate mineral pectolite found only in the Dominican Republic, in the Caribbean. Its coloration varies from white, light-blue, green-blue to deep blue.
Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 2. This opaque, green banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and spaces, deep underground, where the water table and hydrothermal fluids provide the means for chemical precipitation.

Moldavite was introduced to the scientific public for the first time in 1786 as "chrysolites" from Týn nad Vltavou in a lecture by Josef Mayer of Prague University, read at a meeting of the Bohemian Scientific Society (Mayer 1788).

Obsidian consists mainly of SiO 2 (silicon dioxide), usually 70% or more. Crystalline rocks with obsidian's composition include granite and rhyolite. Because obsidian is metastable at the Earth's surface (over time the glass becomes fine-grained mineral crystals), no obsidian has been found that is older than Cretaceous age.

Onyx is a banded variety of the oxide mineral chalcedony. Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands: agate has curved bands and onyx has parallel bands.

Larger stones can be faceted. Rose quartz tends to be milky or cloudy, which deepens its color and provides the effect of adularescence. Transparent rose quartz crystals are extremely rare. Rutile (or rutilated) quartz: Clear or smoky quartz with inclusions of rutile crystals.

Scapolite is not a particularly hard stone, however, with a rating of 5.5 to 6 on the Mohs scale. So it is best used for pendants, earrings and brooches.

The serpentine subgroup (part of the kaolinite-serpentine group) are greenish, brownish, or spotted minerals commonly found in serpentinite rocks. They are used as a source of magnesium and asbestos, and as a decorative stone.
Sodalite is a rich royal blue tectosilicate mineral widely used as an ornamental gemstone. Although massive sodalite samples are opaque, crystals are usually transparent to translucent. Sodalite is a member of the sodalite group with hauyne, nosean, lazurite and tugtupite.

The stone or stone weight (abbreviation: st.) is an English and imperial unit of mass now equal to 14 pounds (6.35029318 kg). England and other Germanic-speaking countries of northern Europe formerly used various standardised "stones" for trade, with their values ranging from about 5 to 40 local pounds (roughly 3 to 15 kg) depending on the location and objects weighed.

Oregon Sunstone contains elemental copper. Oregon Sunstone is unique in that crystals can be quite large. The copper leads to variant color within some stones, where turning one stone will result in manifold hues: the more copper within the stone, the darker the complexion.
Tourmalines have a variety of exciting colors with one of the widest color ranges of any gem species, occurring in various shades of virtually every hue.
In Persia, turquoise was the de facto national stone for millennia, extensively used to decorate objects (from turbans to bridles), mosques, and other important buildings both inside and out, [citation needed] such as the Medresseh-I Shah Husein Mosque of Isfahan.
