AMBERAlthough Amber is usually categorized as a precious gemstone due to some of its qualities, it is actually a fossilized resin. Amber has been known to man since the beginning of time and since Amber forms naturally around the world, it has been used mainly as ornamental jewelry. The largest deposits of Amber are located near the Baltic and Black Seas; in fact, today you can take a net and actually fish for Amber. Usually Amber comes from the floor of the sea that has been fossilized between 30 million and 90 million years ago.
Amber was also given magical powers in ancient and medieval times. For instance, Amber is associated with good luck and the cycle of life. Amber is considered good for longevity, it is also said to make the person wearing Amber more electric or magnetic, ultimately more attractive. It is also said that Amber protected one against rheumatism and gout, as well as a snake bite. Many newborns were given Amber to wear as infants, in order to guard themt from evil forces witches, the devil and witchcraft.
AMBER TreatmentsThe famous Vienna amber factories which use pale amber to manufacture pipes and other smoking tools, apply a specific procedure when working amber: it is turned on the lathe and polished with whitening and water or with rotten stone and oil, the final lustre being given by friction with flannel. During the working a significant electrostatic charge is developed.
When gradually heated in an oil-bath, amber becomes soft and flexible. Two pieces of amber may be united by smearing the surfaces with linseed oil, heating them, and then pressing them together while hot. Cloudy amber may be clarified in an oil-bath, as the oil fills the numerous pores to which the turbidity is due. Small fragments, formerly thrown away or used only for varnish, are now utilized on a large scale in the formation of "ambroid" or "pressed amber". The pieces are carefully heated with exclusion of air and then compressed into a uniform mass by intense hydraulic pressure; the softened amber being forced through holes in a metal plate. The product is extensively used for the production of cheap jewelery and articles for smoking. This pressed amber yields brilliant interference colours in polarized light. Amber has often been imitated by other resins like copal and kauri, as well as by celluloid and even glass. True amber is sometimes coloured artificially. Often amber (particularly with insect inclusions) is counterfeited using a plastic resin similar in appearance. A simple test (performed on the back of the object) consists of touching the object with a heated pin and determining if the resultant odor is of wood resin. If not, the object is counterfeit, although a positive test may not be conclusive owing to a thin coat of real resin. Often counterfeits will have a too perfect pose and position of the trapped insect.

These particles are said to only number about 40 parts per million. Since Citrine is a beautiful looking stone, it is mostly used for ornamental jewelry.
Citrine and Amethyst are the exact same minerals, only the oxidation has changed inside the mineral. You can change the oxidation simply by heating it or irradiating it. In fact, because Citrine is rare in its natural state, a large majority of Citrine sold today is simply Amethyst heated up.
CORALOne of the most distinctive ornamental jewelry items around is Coral. Coral is not a mineral or gemstone per say, it is actually a secretion formed by thousands upon thousands of small organisms. Coral is calcium carbonate, which is essentially like aragonite or marble. Small Coral polyps secrete this material to create a habitat for protection in the sea.
Coral comes in many fine colors including orange, white, black, pale or pink which is called Angelskin Coral and even in a deep red, which is the rarest type and sometimes referred to as fire Coral. While the majority of Coral is used for ornamental jewelry, older Coral reefs that are now found in land are used as a building supply, called Coral rag. There are a few prehistoric Coral reefs that are now found in land on the Isle of Portland, as well as in Africa. Because calcium carbonate is a tough and strong material, it is a great product to build homes and other structures with. Since dried up Coral reefs are usually huge in scale, it is an affordable material as well.
It should be noted that while most of the Coral that is sold is natural and genuine, there are fake Coral products available as well. They are usually created either by plastic, glass or porcelain. It is easy to spot fake Coral because true Coral which is made from calcium carbonate will effervesce when it comes into contact with acid, fake Coral from plastic, glass and porcelain will not.

MOTHER OF PEARLSMother of Pearls is an extremely common type of mineral. While these minerals are extremely beautiful and depending on their quality valuable, they are considered organic minerals because they are created by living organisms.
Mother of pearls are made from mollusks, specifically oysters and abalones. These mollusks secrete calcium carbonate which is silky to the touch and extremely beautiful. Calcium carbonate is generally a hard mineral and will stand up to daily use. While most people are familiar with pearls, mother of Pearls are the same type of mineral except not in a pearl form.
Mother of Pearls are used for a variety of applications. While they can be used as ornamental jewelry, many times Mother of Pearls are used for industrial applications such as home products including tile flooring and materials that are added to fine instruments.

Usually Peridot is found in rocks that are high in iron or magnesium. Unfortunately, Peridot is not found in many regions around the world. This fact is possibly due to the way in which Peridot is very susceptible to weathering. For instance, high heats, water and friction can easily destroy Peridot.

It is also found in volcanic cavities and in pegmatites.

CLEANING GEMSTONE JEWLLERYAfter removing your gemstone jewellery, wipe it with a soft cloth to remove dirt and other residues.
In general, all you need to clean your gemstones is warm, soapy water and a very soft brush-a soft toothbrush and mild dishwashing liquid does a good job. Remove your jewellery, let it soak in the soapy water for about 20 minutes, and then gently brush it and rinse thoroughly. Be careful not to scratch the metal of your setting. Home ultrasonic cleaners are not recommended for all of your colored gemstones. Ruby and sapphire are typically safe to clean in an ultrasonic cleaner but other gemstones are not. Because of their porous composition, opals should never be cleaned in an ultrasonic cleaner. Similarly, emeralds should always be cleaned by hand.
STORING GEMSTONESStore your gemstone jewellery in a lined case or a soft cloth, so the gems do not touch each other or parts of other jewellery. Gemstones are harder than gold, silver, or platinum and can scratch the surfaces of your other fine jewellery if they are not kept separate.
WEARING GEMSTONE JEWELLERYWhile it's true that gemstones such as ruby and sapphire are second only to diamond on the hardness scale, it is not a measurement of their indestructibility. It means that these gemstones are able to resist scratching almost as well as diamond. Abrasive surfaces, harsh chemicals, and sharp blows can damage even the toughest gem. Your gemstone jewellery should be the last thing you put on when getting dressed and the first thing you take off at the end of the night. Store it carefully and it will be enjoyed for generations.
