Diamonds come into touch with a estimate of elements during their formation in the ground and these lead towards their impurities or imperfections. Trapped air is one such element. Even if a brilliant is cut and polished to perfection, the trapped air bubble would still be visible to the naked eye by the way light is refracted by this pocket of air. The pockets of air look like cracks or fissures inside the diamond. These imperfections can greatly sell out the request for retrial of the rock and hence the price.
The process of fracture filling was invented by an Israeli scientist in the 70's. This process involves the use of a clear glass like substance which is forced into the brilliant through the fissures. This glass like material refracts and reflects light just like a brilliant would and hence the brilliant would look somewhat perfect. This process makes the pockets of air disappear and the brilliant would seem exquisite to the naked eye and sometimes even under a microscope.

The filler does not alter a diamonds weight. The brilliant still retains all its qualities in terms of color, shape and carat weight but the clarity improves by one or two grades. The top attainable grade for a fracture filled brilliant is Vs2 and the brilliant appears best and hence the value increases.
Normal wear and tear will not take off the filler from a fracture filled diamond. This however is still a temporary rehabilitation and sure circumstances can take off the filler and cause the brilliant to sustain it traditional look. A jeweler's torch or acid can cause the filler to evaporate. however most rehabilitation lab will certify their work and in these rare cases they will refill the brilliant at no extra cost.
A expert jeweler is able to tell if a brilliant has undergone fracture filling. There is a flash consequent that can be seen when light goes through the filler material. These flashes are great colors that are apparent on rotating the diamond. These flashes are not apparent when the brilliant is viewed form the face up position. They are apparent when the brilliant is viewed from the bottom.
Fracture filled diamonds caused a huge controversy when they were introduced into the Us since some jeweler were fleecing customers by selling them at the price of flawless diamonds without revealing that they had undergone any enhancement.
Today, these types of diamonds are readily sold and suitable by buyers as long as the jeweler discloses that they are enhanced diamonds.
