GEMSTONES GUIDE

INTRODUCTION TO GEMSTONES

 

The gemstone is a mineral or a rock which is used in making jewelry after its proper cutting. Gemstones look like pebbles and rocks but after cutting them properly, they signify beauty. There are many gemstones that have little beauty in their rough state.

Gemstones are nowadays considered an essential commodity in today’s market. In Ancient times, there were no gemstones but nowadays, gemstones are quite popular and people can easily afford them.




THE FIVE FORMATION CATEORIES OF GEMSTONESG
NATURAL GEMSTONES

Natural gemstones are formed in nature, with no interaction of the humans. They will form in different environments from several chemical compositions. They will appear in jewelry after proper cut and polish. But they can not be treated as altered.

GENUINE GEMSTONES

The Genuine gemstones are also natural gemstones, they are commonly treated to enhance the large percentage of appearance of the jewelry manufacturing in the market.

SYNTHETIC GEMSTONES

Synthetic gemstones are natural stones that have physical and chemical quality, and are created in a laboratory. The synthetic version of almost all gemstones is available in the market. Synthetic Gemstones are natural, but they are difficult to identify, they can be identified by the professional jeweler or gemologist only.

IMITATION OR SIMULATED GEMSTONES

These gemstones are natural gemstones, but they do not have chemical compositions and physical characteristics. They are usually less expensive, compared with others. They are made up of glass and plastic material and can be caught up easily by the jeweler.

TREATED GEMSTONES

Several techniques are used by the peoples to improve the appearance of Gemstones. The oldest method to improve the color of the gemstone is heat treatment. But nowadays, there are many techniques to improve the appearance of gemstones, be they by Laser, Heating or by other procedures. Lasers are mostly used to drill the hole in the stone. Some techniques are permanent and some are temporary. For e.g. Drilling is a permanent solution whereas strains, heating solutions, leaks are some temporary solutions. Gemstone’s brilliance is enhanced because of the increasing demand for the gemstones in the recent market.

WHAT MAKES A GEMSTONE UNIQUE

There are mainly six things which make gemstone look unique, desirable and attractive so that everyone loves them. These things are- Beauty in gemstone, Rarity, Durability, Fashion, Personal taste, and Attractive properties. All these are the characteristics that are required to make a gemstone look unique, Attractive, and Desirable.

BEAUTY

A gemstone must have beautiful colors so that people will attract to it. Beauty can not only be described by color but also by shape, size, proper cuts, etc. The gemstone must sparkle through refracting, reflecting, dispersing light. Beauty is further divided into four types, they are Size, Color, Shape, Sparkle.

COLOR

The most important characteristic of a gem to look beautiful is an attractive color. If the color of Gem is not on the mark of choice, then the beauty of the gem can somewhere be lost. Gemstones like Emerald, Ruby, Amethyst, and Sapphire are attractive only because of their color, which attracts everyone. Diamonds that are colorless are less in demand while compared with the colored ones. There are some colors which are high preference colors, as everyone loves them and some other colors have high attention from people. The blue color is one of the high preference colors among all the colors.

SPARKLE

Stone sparkle consists of four things- Facetting, Dispersion, Reflection, and Refraction.

Facetting refers to the number of facets present in the gemstone and if facets are placed properly, then sparkles beauty will enhance. Dispersion refers to the difference between the refraction of different colors of light. A dispersive material that has high split light into its component color gives the color PRISM which shows RAINBOW. Dispersion is also known as fire.

Reflection refers to the stones which reflect light from the surface. Light reflection will depend upon surface reflectivity. Refraction refers to the material of refracted light on alter angles.

SIZE

If the size of the gemstone is large then it magnifies beauty, a proper size matters a lot in the gemstone. If the size is larger, then it has greater desirability. It is necessary for a gemstone to be bigger in size, to be fitted in jewelry, as a small one doesn’t look attractive in jewelry while compared with the larger one. A small gemstone will be the choice of Gemologist only because of rarity.

SHAPE

Shape matters a lot in a gemstone as some preferred heart shape, some preferred round shape, hence everyone has their own choices. There are some stones that are typical in shape, but they can be cut in their desired shape. Every cut has its own and different shape which attracts people a lot towards it and has its different style of cutting and has its own beauty.

DURABILITY

Durability refers to the perfect place of a stone, where a stone may appear on jewelry and looks durable. Durability and Hardness are not the same things. For e.g. try a rubber ball and a bouncing glass bottle, then you realize that the glass is harder than the rubber and the glass bottle smashes. A gemstone has considerable durability while diamonds are considerably indestructible and so on. It is a must know about the durability of a stone to make the jewelry look perfect.

HARDNESS

MOHs hardness is the best way to know about the hardness of scale, except this also there are many ways by which hardness can be measured but, MOHs scale is one of the best methods to know about it. MOH’s scale has a list of 10 minerals on its scale from number 1 to 10. As diamond is the hardest naturally occurring substance, so it is shown as number 10 on MOHs scale. Quartz and Amethyst have been listed as number 7 in the scale, as it is the softest material referred by the professional jewelers. Emerald is listed as 7.5 on the scale because of its hardness. The gemstones which are colorless or transparent have listed on almost 5 to 5.5 on the scale because they do not scratch surfaces because of transparency.

RARITY

According to professional jewelers, rarity is very necessary for the demand of the gemstone. A gemstone will be attractive and beautiful only because of its rarity in the market. The products which are rare have good demand and need in the market, and they are usually expensive, compared with the others because of their demand. Sometimes, you can find rare gems at a cheap price also. The status of a gemstone will also increase because of its rarity. According to some mineral collectors, the value of rare gems is more than the value of other gems, whether they are precious or not.

NATURAL, SYNTHETIC, OR SIMULANT?

Some jewelers and their customers have thought that wearing some natural gemstone accessories can give their look an ambitious look. But some people do not wholly agree with that. They think that rarity can attract them, and expensive gemstones give them the best look. But some do not believe in this also, they think that nothing can make synthetic and simulant it just about the thinking. It’s been up to 7000 years, of the simulants of gemstones and in 1905 synthetic ruby has been produced by the people and spinel in 1908, sapphire in 1911. Pearls are also the stimulant which is produced by the natural process introduced by the human. Cultured pearl has been produced by Oyster by inserting the bead into the oyster. The Oyster has to coat the bead with nacre, and from that natural form is produced. It is difficult to sell the higher priced diamonds to the customer, who doesn’t know about the quality of the gem. So it is natural for some jewelers to threaten progress. There is a huge difference between synthetic, natural, and simulated because not all the stimulants are known as synthetic and, not all the synthetics are called stimulants.

FASHION

Fashion plays an important role in pursuing the material which has been regarded as a gemstone. In the latest trend, moon rock is rare to find and also looks unattractive but earlier it would be regarded as fashionable and regardable in a gemstone. Nowadays, ivory is also not in fashion as a gemstone. Yellow and brown diamonds are regarded as colorless diamonds because they do not attract people. People believe that colored diamonds are going to become our next jewelry fashion trend. Diamond is not much appreciated in England, but other countries loved them.

But now a days this has come to the notice that there are many claims which have non faceted crystals, and they can produce vibrations that protect the wearer from the radiation around them. But the peoples of the current era have to be cynical but tolerant and open minded about all these claims.

RELIGION

There are some bishops, who wear a set of rings that are larger in size as the symbol of their place of work. They wear a set of rings which have stones of red and purple color. The other peoples of different religions will also have this same thinking. Some peoples also think that red color stones will give them special religious significance because the red color represents traditionality.

SOCIAL CUSTOMS

At some places or in some societies and in their culture, people think that the wearing of gemstones will give them ambitious looks, no matter whether it is made up of shells or beads.
