Dear Reader

Welcome to the latest edition, it was a welcome surprise to be asked by Keith & Carole if we’d like to take over the running of the magazine, and a pleasure to
accept(we did feel a little under pressure else the magazine was going to cease entirely! -ED). I’m sure you’ll all join us in thanking Helen for all the hard work she and Tony put into the magazine over the years making it what it is today.
It’s a particular poignant time of the year to begin something new. Already we have a host of new thoughts and ideas for the magazine which we hope will grow from it’s solid foundation, the primarily focus being to help share the knowledge
and appreciation of all things Rock n Gem n Bead with a greater audience.
As always we’d welcome future related editorials, articles and stories on your particular field of expertise, knowledge or passion including books, book reviews, finds, techniques, innovations and humorous tales!
As we ‘put pen to paper’ we overlook the garden, the sun is beating down (for a lucky few mins) we are always surprised how the colours of nature are captured in everything – living, mineral & fossil. The goldfinch that flashes it’s yellow
feathers as it perches among vivid green leaves to the blackbird that hops over the agate, flint & rose quartz pebbles around the pond.
This issue also includes editorials on our trip to Tuscon, crystal healing properties from Rhondie, Baker Agates & Herkimer diamonds from Barry, the latest fossil & gem news and more!
We hope you enjoy, please mention the magazine when contacting any of the contributors or advertisers!

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 things brought to the surface could be positive or negative, love, anger, secrets, but with snowflake obsidian, these things are brought to the surface more gently than they might be otherwise. Snowflake obsidian can provide balance during times of change and is sometimes known as yin yang stone. It aids in seeing patterns in life and recreating them in a more beneficial way.

Coloured Gemstone Report

Our bi-annual Far East buying trips have had to become two week events rather than the one week trips they always used to be. Current market conditions are making most in the trade a little wary.
With the falling pound against the dollar, gemstones and diamonds which are all bought in dollars are generally getting more expensive.
That said, we’re finding sales holding up very well, in fact it seems to be the better-end stones that our customers are finding to be the strong sellers.
Autumn’s Far East visit took in both Hong Kong and Thailand, focusing solely on coloured stones.
The mood amongst dealers was generally subdued with a reduction in the number of buyers and a reduction in the spend of those that did. Taking only what they know they need and little in the way of speculative purchases.
The visit soon revealed an increased number of dealers promoting untreated stones, particularly sapphire and ruby, undoubtedly a result of buyer resistance to the high volume of diffusion treated corundum on the market and the high volume of
lead-glass filled ruby that was evident at almost every turn. Laughably, this material was available ‘certificated’ as “enhanced ruby” with prices ranging from about £9ct to £15pc with sizes up to about 20ct!
There was as usual an abundance of Tanzanite on display but few large pieces in the AAAA grade. We did manage to find a few stunning cushions, emerald cuts and a fantastic AAAA 8ct+ chequerboard short pear shape.
Attention had to be given to avoiding tanzanite with cobalt coatings which have started to appear on the market in recent months. Clues to this treatment include small stones with unusually strong colour for their mass, stones exhibiting paler colour along facet
edges and junctions and stones with an iridescent, almost oily appearance in incident light.
Plenty of large, good quality fresh water pearls are on the market, being a nice round shape with a very high quality nacre.
There were nice examples of Brazilian lavender tourmaline and rubellite. High quality Tsavorite was thin on the ground with much of the material on offer really just too dark and looking more like dark green tourmaline.
Diamond Report
The quite dramatic drop in the value of the Pound against the Dollar is having a marked effect on prices but other factors are also influencing the supply and price of diamonds worldwide.
Ninety percent of the diamonds sold worldwide are cut in the Indian city of Sur at in Gujarat State. An unfavourable rupee/dollar exchange rate is compounding problems for Indian cutters pushing up their costs. Also a reduction in availability of the rough, an expected reduction in buyers have all
combined to persuade some major manufacturers in the post Diwali period to remain closed for up to 6 weeks, holding onto stocks in the hope more profitable economic conditions will return.
Also, African producers such as Botswana, Congo and Tanzania, which account for 45% of diamond production, in a move to end India’s domination over the diamond trade and to kick start a domestic cutting industry are set to impose export duties of 5 to 7% on rough.
The immensely popular 1ct Diamond Packs which we had sold out of, have now been replenished with TLB material in sizes 1mm to 2.75. Exact or “hot” sizes eg 1.5/2/2.5/ 3mm etc are attracting premium prices
as demand is very high with most going to the watch trade for bezels, dials and bracelets.
We’ve been fortunate to find an old Indian cutter who will cut old cuts for us... makes sense I suppose. He’s so old we reckon he never re-trained for cutting the modem brilliant when it was, introduced in the 1940’s and Victorian or “Mitchel” cuts as they are known in India are what he’s always done.
