This is a generic term for any number of black gemstones. Many of them are made of Jasper, but probably also from several other stones that have been dyed black. Therefore its metaphysical properties vary. It has a silky gloss polish, and lacks the luster of Onyx. Blackstone is an inexpensive stone.

The name is often interchangeable with Sard, a darker and more brownish stone. Carnelian has a hardness of 6,5-7 on the Mohs hardness scale, so it is a sturdy stone, and can be used in jewelry worn daily. I find that it resembles red Agate in color, but it is maybe a bit browner in tone. The variation that has white banding, is called Sardonyx. Carnelian is also referred to as Pigeons Blood Agate. It should not be exposed to prolonged sunlight, as it then may redden. Its red-orange color is beautiful if combined with green stones like Jade or with the more toned down Kambaba Jasper.

Agate, Carnelian, Onyx, Jasper, Tiger eye, Sard, Sardonyx, Chrysoprase and Bloodstone are all varieties of Chalcedony.

When the name Chalcedony is used in the gemstone trade, it refers only to the white or lightly colored nodular or massive Chalcedony. The rest is referred to by their respective names.

The color is due to very small inclusions of Nickel compounds. It has a hardness of 6-7 on the Mohs scale, and needs no enhancement or treatment. Dyed Green Agate and green glass is sometimes sold as Chrysoprase, and Chrysoprase is sometimes sold as Jade, so it may be vise to ask for a certification whey dealing with this gem.

Citrine has a hardness of 7 on the Mohs scale, and is therefor a durable stone. It comes in yellowish tones, like yellow, yellow-brown, orange, dark orange-brown and reddish brown. It is a translucent to transparent stone. Unfortunately it resembles the more valuable Topaz, and is sold as Topaz from unscrupulous dealers. Citrine in nature is rare, and it is the most valuable of the Quartz gemstones. Most Citrine on the market is actually heat treated Quartz or Amethyst. A man made “variation” is Ametrine, which is Amethyst heated into Citrine, and then exposed to radiation to turn slightly back into Amethyst in certain parts of the stone.
The natural Citrine is lighter and more faded than the heat treated ones. The heat treated all have a red tint. Because of its transparency it is often faceted.

This is the most common of the Garnets. It is a dark, almost black, opaque variation, but sometimes lighter colored stones are found.

It is also known under synonyms like Almandite, Oriental Garnet and Alabandine Ruby.

Gold stone is not a mineral, but is man-made glass.
This is a man-made synthetic stone which resembles Hematite. It has a gun metal color and is very popular as a “gemstone”. So, if you cannot afford to buy Hematite, go for Hemalyke at the fraction of the price.
Hematite is very distinctive with its metallic lustre. In Greek Hematite means “blood like”, and the name was given because it is red when powdered. It has therefor been used as a pigment. It is one of the most common minerals and is very popular as a gemstone. You can often find it carved into rings or ornaments, and as cabochons. It becomes magnetic when heated, and some of the specimens are iridescent. It may also be known under other names like Hematite rose, Kidney Ore or Tiger Iron. It is beautiful with pearls and silver, or by itself as a strung necklace.
if you love expensive stones like Turquoise, Lapis Lazuli and Coral, but cannot afford them, this is the stone for you. Howlite is naturally a white stone with black and brown veins. It is quite porous and can therefor easily be dyed. It makes a very convincing imitation of Turquoise and is sold as such from unscrupulous dealers. It also makes perfect fake Lapis Lazuli and lately also imitates Coral. As a matter of fact, this stone is famous for its ability to imitate other minerals. However it is beautiful in its natural color, and makes a nice appearance in jewelry with its porcelain-like luster. It is a softer stone and has a hardness on only 3,5, so use it with caution in jewelry that is not meant to be worn everyday.
