Fractures also are a consequence of mechanical stress. They occur at the girdle, and more rarely at the point, of the stone when no culet is present.
FRACTURE:
A crack or feather inclusion on the surface of a gemstone, it can show up as a whitish area because light does not pass through it.

Cleavage and Fracture
Minerals aren't always found as perfect crystals -- they are often partially or completely broken into smaller parts. Just how they break apart is an important identifying characteristic.
Fracture Filling Leftover Marks
While filling the cracks with the glass-like solution there are some air bubbles that get trapped because glass is transparent.
Fractures
Fractures are caused mainly by mechanical stresses like pressure or impact and may run in all directions within the diamond.

Fracture - The breaking or chipping of a stone along a direction other than a cleavage plane.
fracture filled Asilica type substance (similar to glass) is heated to a liquid state and forced under pressure into an open inclusion. When using the term "open" this can be a hairline opening to the surface.

Fracture Filling:
Most often used in emeralds, which are prone to cracks, this process uses a glass-like substance to fill and thereby strengthen the stone. It's a non-permanent solution, but can last for generations.
Fracture
Chipping or breaking of a stone in a way unrelated to it's internal atomic structure. Because of this fractured surfaces are often uneven.

A mineral fractures when it is broken or crushed. Fracture takes place when a mineral sample is split in a direction which does not serve as a plane of perfect or distinct cleavage.
jagged fracture Synonym of hackly fracture: Type of fracture resembling broken metal, exhibiting sharp, jagged surfaces.
Fractures fillings - In diamonds, fracture filling entails a molten glass filling that improves clarity. You can get a lot more stone for your money buying fracture filled diamonds, the problem is that the treatment isn't always permanent.

Fracture is the way a stone breaks. It is a break in a direction other than along cleavage planes and results when the bonding forces are similar in all directions.
FRACTURE
A fracture is a crack or feather in a diamond or gemstone in the opposite direction of its naturally occurring crystals.
Fracture: Uneven to granular
Luster: Greasy to dull

Fracture Filling
Fracture filling is a treatment used to fill-in tiny cracks in a gemstone with a clear, glasslike substance. The cracks don't disappear, but the film creates an optical illusion that makes them invisible to the naked eye.
FRACTURE - A break or chip in any direction not parallel to the planes of the atoms in a crystalline mineral and other than on or across cleavage planes. In other words, any uneven break.

Fracture Filling:
The process that uses a different substance to fill fractures in a gemstone and thereby strengthening the stone; it is a non-permanent solution. This process is common in emeralds but also occurs with other gemstones.
Fracture is a physical property of minerals. It is defined as any break that other than that caused by cleaving or parting. Fractures may be internal or external. Internal fractures are called feathers.
Fracture: A crack or a feather in a gemstone.

A cleavage fracture or fissure with an irregular path inside the stone, usually breaks the surface of the stone.
Crown
The portion of the diamond above the girdle.
Inclusions, fractures, and incipient cleavage cracks all fall under the general heading of "flaws" that affect a diamonds clarity. In grading, no distinction is made among them, except with respect to the extent each affects appearance.
Fissures and fractures that are characteristic of emerald are traditionally filled with oil to minimize their visual impact. Cleaning emerald with an ultrasonic cleaner can remove or damage the oil, thus making the fissures more visible.
Conchoidal..(fracture), A breakage which leaves a conchoidal shell shaped surface.

Amazonite has a soft rating of 5 to 6 on the Mohs Scale and is easily fractured if treated roughly. The gemstone is said to aid in building new business, inspire hope and self confidence, and for some fortunate parents, motivate lazy teenagers.
The luster is silky with a wavy light-ray on fractures. Typically displays stripes, because included fibers are crooked or bent. It is sensitive to acids.
Occasionally, to improve appearance, diamonds are laser-drilled and, sometimes, a foreign substance is used to fill surface cavities or fractures. Diamonds may also be irradiated and/or heated to induce "fancy" colors.
Stones that have a Mohs hardness of less than 8 are highly subject to scratching; harder stones are less likely to be scratched but are still subject to chipping and fracture.
The highest-quality material is a rich apple-green of even color, without flaws, fractures, inclusions, cavities or other imperfections. Much of the chrysoprase used for beads has a brownish matrix.
With the technological advances in the field today many new kinds of treatment are emerging, among them fracture-filling and lasering . For the most part these augmentation techniques are permanent though some are not, and will require special care.
