Sagittarius Horoscope Gemstones

Agate is one of the most varied stones in the mineral world. It is a banded form of chalcedony, and it turns up in shades of red, grey, white, blue, brown and green, usually arranged in the concentric rings that give the stone its signature look. The bands can be opaque in one layer and almost see-through in the next, so a single polished slice often reads like a cross-section of a small landscape.

The name is traditionally traced to the Achates, a river in Sicily where the Greeks were said to have gathered the first pieces. Agate has been cut and carved for at least four thousand years. Craftsmen in Mesopotamia and Rome used it for seal rings and cameos, and the German town of Idar-Oberstein built an entire cutting industry around it. Because agate is tough as well as attractive, pieces were passed down through families rather than worn out.

In the tradition of healing stones, agate is treated as one of the steadier, quieter companions rather than a dramatic one. Different varieties, each with its own colour and pattern, were once matched to different purposes. Old handbooks advised wearing it against the skin, on the theory that the warmth and light of the natural world reached the body more easily through the stone.

Properties of agate

• It was believed to shield the wearer from harm and to help them find their footing in unfriendly circumstances.

• Folk tradition recommended it to people who slept badly, and linked it with a steady, regular metabolism.

• According to old sources, it encourages a clear-eyed view of facts and helps a person see a situation as it actually is.

• Lapidaries describe it as carrying a warm, assertive energy that was long associated with vitality and physical strength.

• It is believed to bring a sense of warmth to tense areas of the body and to help accumulated strain loosen its grip.

• In stone lore it is said to draw off surplus energy, which is why it was reached for during demanding periods.

• Popular belief holds that it makes company easier and helps a newcomer settle into unfamiliar surroundings.

• It has a long reputation as a courage stone, thought to support anyone working through a fear.

• Older writers claimed it sharpens clarity of thought and the ability to reason through a problem step by step.

• Folk medicine connected it with a well-toned body and with the smooth circulation of lymph.

• Traditional belief associates it with balanced blood pressure, particularly when the reading tends to run low.

• It has been carried for centuries as protection against the evil eye, since its bold banding catches the eye first and was thought to absorb ill will.

• Custom held that a child with an agate in a pocket stays calmer and quarrels less.

• It is traditionally counted among the stones of cheerfulness and inner quiet.

Agate stands for worldly success: tradition says it turns away unwelcome energy and restores courage that has worn thin. People in business customarily carried it below the waist, in a pocket for instance, and a ring set with agate was said to strengthen self-assurance in particular. It appeals most to those who want steadiness, calm and a sense of security in ordinary daily life. The uses described here belong to tradition and folk belief and are not a substitute for medical advice.

Amethyst is the purple variety of quartz, coloured by traces of iron combined with natural irradiation deep in the rock. The shade ranges from a faint lilac to the deep reddish purple that dealers call Siberian, and a single crystal often carries several tones in bands or patches. It grows in geodes, hollow pockets lined with pointed crystals, and a cracked-open amethyst geode is one of the most recognisable objects in any mineral shop.

The name comes from the Greek amethystos, meaning not intoxicated. Greeks and Romans believed a cup carved from the stone, or an amethyst worn while drinking, kept a person clear-headed through a long evening. In the Christian church it became the stone of bishops, set in rings as a sign of sober judgement, and it stayed among the most valuable gems in Europe until vast deposits were found in Brazil and Uruguay in the eighteenth and nineteenth centuries, which brought the price within everyone's reach.

One practical detail matters for anyone who owns a piece: the purple is not permanent under strong light. Amethyst left on a sunny windowsill slowly loses colour and can turn pale grey or brownish, so it is kept in the shade when it is not being worn.

Tiger's eye is quartz with a silky, moving band of light running across it. The effect, called chatoyancy, comes from parallel fibres of an older mineral that were gradually replaced by silica while keeping their fibrous alignment. Light reflecting off those fibres gathers into a bright stripe that slides as the stone is turned, exactly like the slit pupil of a cat. The classic colour is golden brown with darker bands, though heat and natural oxidation also produce red tiger's eye, and the blue-grey form is known as hawk's eye.

The great source is the Northern Cape of South Africa, where the stone occurs in ancient banded ironstone. Western Australia, India, Brazil, Namibia and Myanmar supply material too. Because it cuts and polishes well and costs little, tiger's eye became a staple of men's jewellery in the twentieth century, particularly in cufflinks, signet rings and cabochon-set bracelets.

The stone must be cut as a domed cabochon with the fibres running the right way, otherwise the eye does not appear at all. A well-cut piece shows a single sharp line down the centre of the dome, and that craftsmanship is most of what separates a good specimen from an ordinary one.

Properties of tiger's eye

• It is traditionally worn as a stone of courage, taking its reputation from the animal it is named after.

• Folk belief holds that it protects the wearer from ill will, since the eye is said to watch back.

• It is said to sharpen practical judgement when money is involved.

• Traditional accounts link it with willpower and with resisting a tempting shortcut.

• In stone lore it is believed to help a person see through flattery to what is really being asked.

• It has a reputation for balancing extremes of mood, neither over-excited nor flat.

• Popular belief connects it with confidence in front of an audience.

• Older writers recommended it to those beginning a business or taking a calculated risk.

Lapis lazuli is a rock rather than a single mineral, and that is the key to its appearance. The deep blue comes from lazurite; the white streaks and clouds are calcite; and the golden flecks scattered through the best material are crystals of pyrite, not gold, though they have been mistaken for it since antiquity. The name is half Latin and half Persian: lapis, a stone, and lazhuward, a place that gave its name to the colour azure.

Almost all the finest lapis has come from one place for six thousand years. The mines of Sar-e-Sang in the Badakhshan mountains of northeastern Afghanistan supplied the Sumerians, the Egyptians who inlaid it into Tutankhamun's funerary mask, and the medieval European painters who ground it into ultramarine, the most expensive pigment ever used. Renaissance contracts specified how much ultramarine a painter could use, because it cost more than gold and was reserved for the Virgin's robe.

Lapis is soft, porous and often stabilised or dyed, so it needs restraint in cleaning. Water works its way into the rock and can loosen the calcite or rust the pyrite, and strong light dulls the blue. A dry cloth and a shaded box are the whole routine.

Properties of lapis lazuli

• It is traditionally regarded as a stone of truth, worn by those who must speak honestly for a living.

• Folk belief holds that it helps a person say what they actually mean rather than what is expected.

• According to old sources, Egyptian officials wore it as a sign of sound judgement.

• It is said to support the throat and anyone who uses their voice all day.

• Traditional accounts link it with wisdom gathered from experience rather than books alone.

• In stone lore it is believed to calm the mind before difficult news must be delivered.

• It has a long reputation as a stone of royalty and of dignified authority.

• Popular belief connects it with self-knowledge and with facing an uncomfortable truth about oneself.

• Older writers recommended it to teachers, writers and anyone explaining complicated things simply.

• It is thought to relieve the tension of a long day spent among many people.

• Folk tradition treats it as a charm against being deceived in a bargain.

• It is said to encourage friendship built on candour rather than convenience.

• Traditional belief holds that it steadies the nerves before a performance.

• It was placed in tombs and shrines as a stone of the night sky and of what lies beyond it.

Sodalite is a rich royal blue mineral, usually veined and mottled with white calcite, and it is often mistaken for lapis lazuli at first glance. The reliable difference is the pyrite: lapis carries golden flecks, sodalite does not. Sodalite also tends towards a more even, slightly softer blue with a lavender or grey cast, and it is noticeably lighter in the hand. The name is simply descriptive, from the sodium in its composition.

The mineral was first described in 1811 from material found in Greenland. Its reputation was made a century later, when a large deposit at Bancroft in Ontario supplied stone for the Marmora quarry shipment sent to Britain in 1901; Princess Patricia of Connaught chose it for the decoration of Marlborough House, and the variety has been called Princess Blue ever since. Brazil, Namibia, Russia and Bolivia are also significant sources. Sodalite is carved into bookends, boxes, tiles and beads, where the broad blue surfaces show at their best.

It is a moderately soft, porous stone. It should not be soaked or left in sunlight for long stretches, and it dislikes the acids in household cleaners. A dry cloth is enough.

Properties of sodalite

• It is traditionally regarded as a stone of rational thought, favoured by those who work with logic.

• Folk belief holds that it settles a mind that is going round in circles.

• According to old sources, it supports anyone who has to explain a complicated idea clearly.

• It is said to encourage the confidence to state an unpopular opinion calmly.

• Traditional accounts link it with the throat and with speaking without a rush of nerves.

• In stone lore it is believed to reduce the mental noise of a crowded workplace.

• It has a reputation for helping a group reach agreement, which is why it was kept on meeting tables.

• Popular belief connects it with self-discipline in study and long training.

• Older writers recommended it to those who avoid confrontation to their own cost.

• It is thought to make it easier to admit a mistake early rather than late.

• Folk tradition treats it as a stone of objectivity, cooling emotion enough to see facts.

• It was carried by writers and researchers as a companion for solitary work.

• Traditional belief holds that it eases the restlessness that keeps a person from finishing a task.

• It is said to strengthen trust between people who must rely on each other's word.

Topaz is an aluminium silicate containing fluorine, and it is one of the hardest of the commonly worn gemstones. It grows in tall, well-shaped prismatic crystals, sometimes to remarkable size, and it has a perfect cleavage in one direction that cutters must respect. Colourless topaz is the most abundant form, but the stone also occurs in sherry brown, pale blue, pink and, most prized of all, the golden orange with a pink flash called imperial topaz.

The name may come from Topazios, an island in the Red Sea now called Zabargad, or from the Sanskrit tapas, meaning fire. Ouro Preto in Brazil has been the great source of imperial topaz for three centuries, and the Ural mountains, Pakistan, Nigeria, Sri Lanka and Myanmar contribute other colours. Most bright blue topaz on the market is colourless material that has been irradiated and heated, a treatment developed in the twentieth century that made a once-rare colour widely available.

Its hardness makes topaz excellent for rings, but the cleavage means a sharp knock in the wrong direction can split it cleanly. Ultrasonic cleaners are avoided for the same reason, and coloured varieties are kept out of prolonged strong light.

Properties of topaz

• It is traditionally described as a stone of clarity and honest intention.

• Folk belief holds that it strengthens the will of someone who has been drifting.

• According to old sources, it was worn as a guard against deceit in business.

• Traditional accounts link it with the solar plexus and with a well-founded confidence.

• In stone lore it is believed to sharpen the ability to set a goal and name it plainly.

• It has a long reputation as a stone of good fortune, particularly the golden variety.

• Popular belief connects it with generosity and with pleasure taken in giving.

• Older writers recommended it to those beginning to teach or to lead others.

• It is thought to steady the nerves of someone under public scrutiny.

• Folk tradition treats it as a charm against night fears, kept beside the bed.

• It was given as a token of friendship renewed after a long absence.

• Traditional belief holds that it supports recovery of appetite and good spirits together.

• It is said to help a person forgive themselves for an old error of judgement.

Topaz symbolises clear purpose, warmth and good fortune earned rather than stumbled upon. It appeals to people who want a hard, brilliant stone for daily wear, to anyone drawn to golden or sky-blue tones, and to those who like a gem with an unusually clean look. The uses described here belong to tradition and folk belief and are not a substitute for medical advice.

Turquoise is an opaque copper aluminium phosphate, and it is the copper that gives it the sky blue that no other stone quite matches. The colour shifts towards green as iron replaces some of the aluminium, and many specimens are crossed by a web of veins in gold, brown or black, the remains of the host rock. That webbing, called matrix, means no two pieces look alike. The name reached English through French, pierre turquoise, the Turkish stone, because the earliest supplies arrived in Europe by way of Turkey rather than from Turkey itself.

Turquoise has been mined for at least six thousand years. Egyptian expeditions worked the Sinai for it, the mines of Nishapur in Iran produced the intense blue that became the standard of quality, and Tibetan and Central Asian craftsmen set it into ritual objects. In the American Southwest, Pueblo, Navajo and Zuni silversmiths built an entire jewellery tradition around it, and their silver-and-turquoise work is now recognised worldwide.

Two things must be understood about this stone. It is soft, softer than window glass, so it scratches and chips more readily than most gems. And it is genuinely porous: it absorbs water, oil, perfume and perspiration, which can turn the blue green or crack the surface as the stone dries out. Much commercial turquoise is stabilised with resin for this reason, and untreated material is never soaked or worn in the shower. A dry cloth and shade from strong sunlight keep it as it should be.
