See image below of Flaws and Inclusions in a Diamond.
Feathers: cleavages or fractures often white and feathery in appearance. (There are 4 cleavage planes in diamond, which run in octahedral directions.
Feathers: As the name suggests these inclusions are the referred to fissures that group together and looks like feather. It is usually seen in the gemstone.
FEATHERS. White subtransparent lines in the body of a stone.
FEMININE. Rubies of a pale tint.
FERROUS. Any mineral substance having a considerable portion of iron in its composition.
Feathers: These are small fractures in a diamond.
Finish: This term refers to the qualities imparted to a diamond by the skill of the diamond cutter.
Feathers can occur during the formation of a gemstone, perhaps as a result of rapid heating or cooling, or through pressure or mechanical stress. They can also occur long after the formation process, for the same reasons.

Feathers - An internal flaw (inclusion) in gemstones that can begin on the surface of the stone and work deep inside. They can either add character, or destroy value, depending on how much they block color uniformity and threaten durability.
Feathers
A fissure in a precious stone or diamond, usually only a tiny crack. The feather may not affect the strength or beauty of the stone, but depending on the depth or location can make the gemstone more fragile and susceptible to cracking ...
Feathers are small fractures in a diamond caused by the tremendous stress that the diamond suffered while it was growing underground. Under magnification, these small fractures appear very much like a feather.

Sea shells work well when combined with crystals, feathers, or other shamanic tools. They are especially useful to counterbalance overly dynamic energies due to their watery nature.
Typical flaws include tiny pinpoints, faint clouds, tiny feathers, or internal graining.
VS1, VS2 (very slightly included) - Very small inclusions and/or finish faults, somewhat difficult for a trained eye to see under 10x magnification.
Feathers can get larger with a hard knock and thus considered more problematic than any other inclusion.
bearded girdle
Fine feathers scattered around the diamond's perimeter. If it's heavy, it can go all the way around the stone.

In its widest sense the term jewelry encompasses objects made of many kinds of organic and inorganic materials such as hair, feathers, leather, scales, bones, shells, wood, ceramics, metals, and minerals.
Two of the most common inclusions are crystals and feathers. Crystals are merely minerals trapped inside the diamond; feathers are tiny breaks in the diamond. Blemishes are usually very small and are only on the surface of a diamond.
Inclusions typically consist of crystals, clouds and feathers. Crystals are tiny minerals that become trapped inside a diamond during its formation.
Structural color is responsible for the blues and greens of the feathers of many birds (the blue jay, for example), as well as certain butterfly wings and beetle shells.
Inclusions may take the form of dark specks, light-colored planes called "feathers", voids, general cloudiness, and other types of imperfections.
Most diamonds contain some blemishes (crystals, clouds, or feathers), which can be found inside the stone (called inclusions). Surface blemishes are not considered a major concern, since they can often be polished away.
Contains minute inclusions such as small crystals, clouds or feathers when observed with effort under 10x magnification.
Feathers
-All types of cracks which are perpendicular to the crack plane and appear white and feathery are termed "feathers" or "glets". Also small blow marks and indentation marks on the edge of a facet are sometimes so described.
The seller requested that only serious international inquiries be sent, which indicated that he was aware that it was illegal to sell eagle feathers in the United States.
Density - The density of a substance depends on both its mass and its volume. For example, feathers are less dense than lead. 1 tone of feathers will have a greater volume than 1 tone of lead.
Internally, inclusions may occur in the form of tiny spots, fractures, feathers etc., while externally they may appear as scratches and fissures. Sometimes an inclusion does not affect a diamond's brilliance or gets easily hidden by its setting.
If a yellow sapphire has been heated at a high temperature these feathers are destroyed and are easily identifiable by a trained gemologist.
Some specimens show a sheen (silk) and some have an interior series of minute, needle-like inclusions (feathers) of rutile; these, when properly cut en cabochon, are star rubies and star sapphires or, when having only one ray of light, ...
Mong Hsu rubies also contain healing feathers, several distinct growth zoning patterns, and very fine white needles on inclusions in untreated stones.
Homogeneous growth of the crystals almost always causes feathers and zoning.
These inclusions may appear as clouds, feathers, veils, silk fibres or rutile needles.
Inclusions consisting of surface crumbling, often accompanied by tiny, rootlike feathers .
Burned Facet
This facet may appear whitish, or burnt, as a result of the cutter polishing the facet "against the grain".
Surface inclusion with crumbling on the diamond's surface along with tiny feathers.
Bruting
Cutting or girdling. Process involves grinding one diamond against another to give it its basic shape.
As the sticky resin rough amberoozed from ancient pine trees, small insects, plant material, feathers and other small objects in the path of the flow became entrapped.
Jewelry strung on a thin leather cord has become popular recently. Pendants, beads, shell, feathers, and/or sharks teeth are strung on leather to make interesting necklaces and bracelets.

Additionally, small pinpoints or feathers do not usually affect fancy colors due to the deeper coloring of the diamond. Fancy diamonds of VS or better clarity are more uncommon in nature and therefore command a greater price.
Amber resin can ooze from trees and fill internal fissures trapping debris such as seeds, leaves, feathers and insects, which are buried and fossilized through a natural polymerization of the organic compounds.
Aigrette: A jewelled hair ornament usually in a spray-like pattern to simulate feathers. Aigrettes were in and out of popularity from the 17th to the 20th century.
Aigrette - an ornament worn in the hair, often decorated with feathers or glitter. Very popular in the early 20th century.
Inclusion can be bubbles, crystals, carbon spots, feathers, clouds, pinpoints, or other impurities, or even cracks and abrasions. They are what make a diamond so unique, as a fingerprint does for a person.
Bruise: Damage consisting of surface crumbling, often accompanied by tiny, root like feathers.
Burn mark: Surface clouding caused by excessive heat.

Although they may have no affect on the strength or beauty of the diamond whatsoever, these feathers, or "fissures" as they are sometimes called, can make a stone more fragile and susceptible to cracking depending on the depth or location.
LEATHER CORD JEWELRY
Jewelry strung on a thin leather cord has become popular recently. Pendants, beads, shell, feathers, and/or sharks teeth are strung on leather to make interesting necklaces and bracelets.

These gemstones may contain insects, plant material, feathers and other small objects that were trapped millions of years ago when the resin was sticky. Amber is quite soft but perfect for jewelry as it can be easily cut, etched, faceted, or carved.
A feather is an internal flaw (also called an inclusion) in a gemstone that can start at the surface of the stone and extend deep inside. Feathers can either ruin a stone (by making it fragile and/or changing the color), or add to its beauty.
I
INCLUSION - Internal characteristics present in gemstones. Common diamond inclusions include feathers, crystals, fractures, graining, pinpoints, and cavities.
Internal fractures are called feathers. External fractures often take characteristic forms that are helpful when identifying minerals. Adjectives used to describe fracture include conchoidal, splintery, even, uneven, irregular, and granular.

Feather
Feather is an inclusion or an internal flaw of a gemstone. There are different grades of inclusion and most are invisible to the naked eye. Feathers can decrease the value of a gemstone.
Spectrolite is a variety of Labradorite which displays intense reds, oranges and yellows and even blues and greens. The colour play in the stone is glistening like the feathers of a peacock or the Northern Lights.
Feather When the plane of cleavage or fracture in a diamond is viewed at right angle to it, the appearance is often reminiscent of a feather. Thus, cleavage and fractures are often called "feathers." ...
These different colors are due to the light interference by thin lamellae, in parallel layers, within the spectrolite. The color play in the stone is iridescent as in the feathers of a peacock or the Northern Lights.
(Structural flaws like feathers and cleavages can be damaged by the high pressure exerted by the prong on the diamond to hold it snug in the ring.) ...
catch all term used to describe any number of optical or physical properties; these are determined to be negative in nature when viewing the gem. They could include but not limited to the following: carbon spots, internal crystals, clouds, feathers, ...
