FLUOROSCENTS DIAMONDS


FLUOROSCENTS DIAMONDS

Fluorescent diamonds is a diamond which imparts color while expose to UV light or sunlight. The molecules in the crystalline structure get excited and begin to fluoresce. The more excited molecules get the stronger fluorescence which emits different strength of a diamonds. Every stone has some amount of fluorescence in it. Some executes negligible while other executes this property very strongly. Fluorescent scale is given below ranging from negligible to very strong:

NONE  >>  NEGLIGIBLE  >>  FAINT  >>  MEDIUM  >>  STRONG  >>  VERY STRONG

Fluorescent stones are transparent too; this means possessing fluorescence property will not affect its transparency. According to GIA (GEMOLOGY INSTITUE OF AMERICA) average person could not make a difference between fluorescence diamond and normal diamond. We can perform the experiment to check whether your diamond is fluorescent or not. By performing several steps we can identify its fluorescence nature. First we have to place a diamond on a clean surface. Secondly we will emit UV light upon diamond. As a result we can see that if a diamond turns milky and fluorescence than that diamond is fluorescent diamond. And if diamond glows slightly it also poses some fluorescent property. And when  it do not respond while UV light falls on it and shows no change that diamond do not have fluorescent property. Some other property has been examined such as phosphorescence. Phosphorescence can be elaborated as; when you take diamond away from the ultra violet light it will continue to fluorescence. This property can be noticed in very rare diamonds. Let’s have look towards some positive and negative factors of fluorescent diamonds.

Positive factors of Fluorescent Diamonds:
  •  Medium, strong, very strong fluorescence can be discounted to a graded degree.
  • No impact on the transparency of diamond.
  • It can make warmer color diamonds look whiter than what they actually are.
  • Fluorescence can be seen in natural sunlight or natural daylight.
  • Diamond appears wider than its actual size under natural daylight as it has long –wave UV rays.

Negative factors of Fluorescent Diamonds:
  • Diamonds look oily and chalky which do not have property of strong or very strong fluorescence.
  • Fluorescence can make a diamond appear hazy in certain lighting.
  • Diamond graining can also make diamond appear milky.


Types of Diamond


Types of Diamond

  1. Natural Diamond      
  2. Treated Diamond     
  3. Man-made Diamond     


Natural Diamonds:

Diamonds - the hardest material ever found on the earth by humans known as Natural Diamond. It is made up from primarily carbon. Its unique structural formation makes it the hardest substance ever known. It take millions of years to form and are created naturally deep inside the earth mantle, as it takes long span of time for formation it is very costly. Its amazing characteristics make a stretch in its uses from ornamental production to industrial purpose, as they are good conductors of heat.
  

Treated Diamonds:

It is very rare to find perfect diamond without any flaws however treated diamonds are also natural diamonds but altered by technology. It is also called ‘enhanced diamond’ which are treated to improve clarity grade so that it appears translucent and show perfect shape. Its color and purity has been changed by heating under pressure.


Manmade Diamonds:

Manmade diamonds are also known as synthetic diamonds. These types of diamonds are developing under expert supervisions where the same kind of environment is created inside a laboratory. This technology has been around long time. The same pressure and same temperature (heat) is created to genuinely replicate natural diamond with synthetic one.
This diamonds appear same as natural one by look and properties too. There are two types of manmade diamonds:
·        CVD – Chemical Vapor Deposition
·        HPHT– High Pressure  High Temperature


Chemical Vapor Deposition Diamond:
CVD is a method in which hydrocarbon gas is being treated in special surrounding to grow diamonds. This diamonds are required substrate preparation choosing an appropriate material and its crystallographic orientation, feeding varying amounts of hydrocarbon and non-reactive gases into a chamber and energizing them. The required diamond is formed after several cycles of treatment. This diamonds also have semiconductor properties which is further uses for industrial purpose as well.

High Pressure High Temperature:                                      
HPHT is a scientific procedure which is performed inside laboratory where temperature and pressure is raised much higher to produce genuine facsimile mined diamonds. The price of lab grown diamonds is fairly comparable with natural one. It shows the same optical and chemical property. The 4Cs still apply: cut, clarity, carat and color. 

We will go in depth to each type of Diamond in next articles separately. 

ABCD of Diamond


ABCD of Diamond ?

Yes you read right. Its ABCD of Diamond instead of 4C of diamond. The world of Diamond gone beyond 4C which represent Color, Carat, Cut and Clarity. Nowadays the first question is like "Is it Natural, CVD or HPHT?" and Second is  "How authentic is it?". Then the buyer go for 4C parameters. So looking at the situation we have decided to update knowledge of our readers by writing series of articles about Diamonds. This will include basic information about Diamond to modern and scientific updates in industry. And from history of Diamond to latest trend and beyond it our future prediction about Diamonds. We will try to answer your questions too. So subscribe to this site and get ready to fly in journey of updating your knowledge and belief about Diamond. We will be happy if you suggest us the topic which you wanted to know about in this segment.
