whats in a name?

A rose by any other name would smell as sweet said the Bard but would diamonds shine as bright if known as crystallised carbon or ruby as red corundum.

Many of the gemstones we use and cherish today have been known since ancient times and some of the names that we still know them by have come down from the Egyptians, the Greeks and Romans, from the New World and the Orient. Many of these names have been incorporated in the legends and properties ascribed to the stones. Here are some that I know — if you know of others please share them with us.
Janet Mitchell 2008 Rough rock, cut stones Et jewellery sold by Janet Et Eric Mitchell in aid of the Children's Society. (Reg. charity 221124)

Alexandrite - This gem with its clear colour change from green in sunlight to red-violet in artificial light was first found in Russia and a magnificent specimen was presented to Tsar Alexander I for whom it was named.

Amethyst - The name comes from the primitive Greek 'A and Methustes' meaning not drunken and it was thought that the stone protected the wearer from drunkenness. I don't somehow think it will work against breathalysers.

Apache Tears - This spherical form of obsidian is found in the Arizonian deserts and legend has it that a group of Apache warriors finding themselves outnumbered by 'palefaces' threw themselves from a cliff rather than surrender. The tears of their grieving relatives were turned to stone and can still be found today. This obsidian can be faceted and produces an unusual gem not unlike smoky quartz.

Apatite - Known to the Greeks and found in a broad range of colours, this gem's name come from 'Apaptos' meaning deception because it could be used to mimic other gemstones. An interesting fact is that teeth contain a lot of apatite.

Aquamarine - A member of the beryl group this blue-green stone is named from the Latin "aqua marina' meaning sea water referring obviously to its colour.

Aventurine - The name may derive from the Italian 'a ventura ' - chance, since it resembled an unusual Venetian glass accidentally produced in the eighteenth century. Bright flakes usually, mica or hematite. included in quartz or clear feldspar (usually green or red-brown) cause a glitter effect.

In this issue we continue the magical properties of gems starting with 0 & P

Obsidian is a volcanic lustre rock formed during volcanic activity. It is usually a black or brown glass like rock that sometimes portrays other colours such as blue, purple and green as well as gold and silver sheen. Obsidian is a very protective and grounding stone, and has been used by shamans and crystal healers for this as well as for removing negativity and protection against psychic attacks. It has been shaped into parabolic mirrors and disks for scrying for vision quests and helping to tune into the spirit world. The different colours can work on the different chakras according to colour and the rainbow obsidian on all the chakras and is known as the stone of
pleasure as it helps to induce happiness and joy. Snowflake obsidian has the property of bringing things to the surface.

The presence of Phenacite gathers the energies of the other stones and facilitates the effectiveness of the healing.

MOSS and PLUME AGATES

Continuing Barry’s passion for inclusions in anything, this issue it’s Agate.

Plume Agate
Another type of structure often seen is called a plume, here wispy examples can be found in either agates or cut quartz. Inclusions often look like smoke drifting over red flames, like burning stubble on a farm or the Indian Smoke-signals seen in classic westerns. The plumes themselves can comprise various colours and they often have a halo or corona surrounding them. When this structure is identified, it can be found adjacent to or even included with other manganese dendrites. The distinctive types often overlap, plume structures are also found in other material such as jasper.


Moss Agate
This agate type is also referred to as Mocha stone, they are the same type. Moss Agate is a delicate fluffy structure that is often found in agates; here you can imagine walking through an enchanted forest with soft delicate fronds of moss hanging from the branches of trees. Gem cutters will often give the various individual varieties descriptive names, like green moss agate or a yellow moss agate. Three-dimensional green fronds with a moss like structure, similar to dendrites often occur in a translucent or opaque Chalcedony such as the green tree moss agate. Moss Agates are also found in other bright colours, rather than the typical green moss structure we are used to, the background is often very colourful too. The colours are the result of trace amounts of a metallic element usually an Iron oxide.
Fine green fronds or stringers are often found in a translucent chalcedony envelope. Other Moss Agates can often be found in opaque tubes which when cut open or through, reveal the typical green centre in the tubes. A large variety of colourful moss agate types exist, as more and more varieties are discovered every year, this can be very confusing, as the subtle varieties do frequently overlap in the original material. Another moss like agate that is referred to as Mosquito Agate, seems to be a denser form of moss agate, the sample I have is from Botswana.

Cutting and polishing
Unfortunately for the jewellery makers, many varieties of moss inclusions look their best when backlit. When this occurs they are cut into smaller carefully crafted pieces, set with perhaps a reflective backing, or often no backing at all, making maximum use of any available light.
