Andalusite and some of its Properties.
Andalusite holds the everlasting colours of the season of Autumn. It varies in colour from a pale yellowish brown to a dark bottle-green, dark brown or the most popular, greenish red.
It has a very strong and distinctive pleochroism, so that, when turned, the stone may appear yellow, green and red. A true mimic of the beautiful colours of Autumn.
Large crystals may be vertically striated prisms with a square cross section and pyramidal ends. These are rare. More usual are opaque, rod-like aggregates of crystals or waterworn pebbles. It is these pebbles that are usually cut as gemstones.
Andalusite is an aluminium silicate. It was discovered at Almeria in the southern Spanish province of Andalusia, from where it gets its name.
It is heated to form mullite, a refractory material with industrial uses such as spark plugs.
Some crystals have carbonaceous inclusions, arranged so that in cross section they form a dark cross. This variety is called chiastolite, named after the Greek for “cross”. Chiastolite existed in schists near the town of Santiago de Compostela, northern Spain. Many amulets of the “cross-stone” were sold to pilgrims. This variety is also found in Australia, China, Siberia, Russia, France, England and United States to name a few.
Agate and some of its properties.
Agate is distinguished by its many, often vivid colours . The bands of colours may be white, red, blue, grey, mauve, brown or black. These are irregular and sometimes curved. The parallel bands follow the wavy contour of the cavity where silica gel solidified.
The stone’s name was derived from the River Achates in southwest Sicily, since it was discovered in that area. This gemstone is one of the oldest known minerals. It was valued by the ancient Sumerians and Egyptians who used it for amulets, receptacles and ornamental pieces.
The Greeks and Romans carved it into cameos and intaglios, and the latter used it for intaglio signet rings.
This stone was especially valued during medieval times. Today it remains very popular for brooches, cameos and other jewellery. It is used as a decorative stone for inlaid work, such as boxes, table tops, table mats, clock faces and ornaments, to name just a few.
Agate can be translucent, transparent, or sometimes opaque. Wavy bands are often inside a geode (nodule) of Agate. The colourful bands are best seen when the geode is sawn through and the flat surfaces of the sections are polished. Cutting the stone into thin slices allows light to pass through and display the bands.
All Agates respond well to polishing and they are strong enough for everyday jewellery.

Gemology and Gemstones
In Gemology, Gemstones are the precious stones pieces naturally; these are then polished and finished for the various purposes. The most common purpose of using gemstones is for creating jewellery. There are different varieties of gemstones that seem same but they are different in their composition. Gemologists, who describe gems and their characteristics using technical terminology specific to the field of gemology, identify gemstones.
The first method preferred by a gemologist is to identify a gemstone by its chemical components. As there is no such grading system for any gemstone universally, other than white (colorless) diamond, this gemstone is graded using a system developed by the Gemological Institute of America (GIA). In olden times, all such gemstones were graded by simply checking their color appearance and visibility. In the early 1950’s the GIA system introduced a technical system for this purpose, the prologue of 10x magnification as the standard for grading clarity. Some gemstones are still graded using the old methods or simply by the naked eye. This is Gemology.
Gemstones have been divided into two groups; precious and semi-precious. These days diamond, ruby sapphire and emerald considered as “precious”, these categories was mainly based on trend and the composition of these two lists has changed frequently over time.
Color, cut, clarity and carat are the parameters decided as an aid to help the consumer in understanding the factors that were use to grade a diamond. With few alterations, these specified groups can be useful in understanding the grading of all gemstones.
The four criteria carry different weight that depends on their application to colored gemstones or to colorless diamond. In case of diamonds, cut is the most important determinant of value followed by clarity and color. Diamonds has the property to sparkle, to break down light into its constituent rainbow colors, chop it up into bright little pieces and deliver it to the eye (brilliance). This is a basic function of cut. The original rough form of a diamond, is crystalline and will not exhibit these properties. After its proper fashioning or “cutting”, diamond show these properties. In case of colored gemstones, including colored diamonds, the purity and beauty of that color is the primary determinant of quality.
Turquoise is the lovely blue gemstone that is used in December birthstone jewelry. It is a bluish green stone that has been used since at least 6000 B.C. when the Egyptians used it in mosaics and decorative work and in the jewelry worn by their Pharaohs. It was also used more recently by Aztec kings, in masks, shields and knives, and by Native Americans and the Persians in beautiful ornamental pieces and jewelry. Turquoise is a relatively rare gemstone. Turquoise of gemstone quality is mined in Australia, Iran (formerly Persia), Afghanistan and in the US in New Mexico, Arizona and other Southwest regions.
The name turquoise is thought to come from the French word meaning Turkey as it was mistakenly believed that the gems were mined in that country as they were traded in the bazaars to European merchants. In reality they almost certainly came from the Iran or the Sinai Peninsula. It may possibly also have arisen from the French word for dark blue stone, pierre turquin. It is usually found in copper deposits generally in arid, dessert conditions.
Before turquoise was found in the USA the finest quality gems, with an intense blue color, were found in Persia and ‘Persian Turquoise’ is still used these days to signify the finest quality gemstones. In the last years of the nineteenth century turquoise was found in the United States with deposits that were the equal of the quality of the Persian gemstones. Nowadays the USA is the major producer of this gorgeous precious stone.
One of the first gemstones to be mined, Turquoise has long been prized for its intense colour, which varies from sky-blue to green depending on the quantities of iron and copper within it. Turquoise is commonly found in microcrystalline, massive form, usually in encrustations, in veins, or as modules. It is opaque to semi-translucent light and very fragile, with conchoidal fracture. Some material is very porous, leading to fading and cracking, so it may be impregnated with wax or resin to maintain its appearance.
Ruby and its properties.
Ruby is a very rare gem. They exist in many shades of red, from pinkish to purplish or brownish red. The red colour is determined by the amount of chromium, which further enhances the colour by causing a red fluorescence.
Most rubies show purplish red to orangey red hues. However the overall colour (colour being a combination of hue, tone and saturation) can provide gem dealers with an indication of the stone’s original geographic origin. Burmese Rubies tend to be purplish red in colour, while Thai stones tend to be brownish red.
For centuries, Ruby was said to remove sadness, prevent nightmares and protect against many illnesses. With its likeness in colour to blood, it has often been said to help stem haemorrhages and cure inflammatory diseases. Besides their obvious value as a precious gems, rubies are also used extensively in laser technology.
The great value of rubies is mentioned in the Bible. Ruby mining goes back more than 2500 years in Sri Lanka and was recorded in the sixth century AD at Mogok, Burma. The Burmese wore the stone as a talisman to protect them against illness or misfortune. Many in the ancient world believed they could predict the future based on the changing colour of the ruby they wore. The rare and highly valued “pigeon’s blood” variety now mined in Burma was previously called “blood drops from the heart of the earth” by the Burmese.
Large natural Rubies of good colour and clarity are so valuable that they often demand a higher price per carat than even the most flawless Diamonds. For example, in 1988 Sotheby’s auctioned a 15.97 carat Ruby which sold for more than $3.6 million dollars under the hammer.
Bloodstone and its properties.
Bloodstone is also known as “heliotrope” which is an opaque green variety of chalcedony. The name, Bloodstone, was chosen because of the stone’s many red spots which are caused by Haematite. This is due to the red spots resembling drops of blood.
The red spots on the normally dark green gemstones are caused by the presence of iron oxides.
The heliotrope name comes from the Greek words helios meaning “sun” and tropos meaning “turn”. This is because in ancient times they believed it could turn the rays of the sun red and, if put into water, would show the sun as a blood red image.
The ancient Greeks and Romans believed that if worn by athletes they would gain endurance. Medieval people believed that Christ’s blood dripping down from the cross caused the red spots and therefore it had special powers such as stopping a haemorrhage if touched.
Bloodstone is porous and quite soft but is a very popular gemstone, usually cut as a cabochon.
