Selection of rutile quartz depends on the attractiveness of the disposition of the inclusions.
The name is from the Latin "rutilus", which means "golden-red". There are three polymorphs of Titanium Dioxide, rutile, anatase, and brookite. Rutile is by far the most common. It is an important ore of titanium.

Rutilite, also known as Rutile, is a mineral which consists of titanium dioxide, generally with a little iron. It is typically of reddish-brown in color, but deep red or black, with brilliant metallic or diamond-like luster is also seen.
Rutile Composition
Rutile is a crystalized mineral that is composed of titanium dioxide which crystallizes in the tetragonal crystal system, usually forming into a prismatic or twinned configuration.
Rutile
A mineral that is reddish-brown to red, sometimes yellowish, and has a brilliant lustre. It is sometimes found as a needle-like inclusion in some gemstones, e.g. Sagenitic quartz and sagenite.
Rutile
The most common and familiar inclusion in quartz is rutile. The needle-like crystals can be thick or thin, pale gold to rich orangey brown and arranged in dense or sparse patterns.

saturation The quantity of color in a gem which translates into the color's vividness or dullness.
Rutiles
A titanium dioxide mineral with needle-like inclusions (or foreign matter) within a stone. The rutile needles can be reddish (which is what rutile means in Latin).
Rutiles: Needle-like inclusions within a stone, which can produce such gem phenomena as an asterism (or star) and a cat's-eye, depending on the direction of the rutiles.
Rutile
The term used for metal flecks or crystals inside gemstones. A type of inclusion.
A type of hoop earring, often called saddle hoop earrings, wherein the hoop is enlongated vertically creating a more elliptical, saddle-like shape.

Rutile is a major ore of titanium, which is a metal used for high tech alloys. It often forms needle-like crystal inclusions inside quartz. This form of quartz is known as rutilated quartz and it looks like small bars of imbedded gold.
rutile (n) the mineral titanium dioxide. Rutiles sometimes feature as inclusions in other gemstones. Rutile inclusions are often needle-like and may also produce asterism effects, e.g., in rubies.

Rutile adds a high-energy dimension, making this an excellent stone to program for your goals for faster manifestation. It is especially effective for those who want, through the realization of their personal dreams, to make a difference in the world.
Included rutile needles or hematite plates are called 'silk', which bring about a soft sheen in the stone.

Microscopic rutile inclusions, commonly known as silk, are a typical characteristic of rubies. When evenly distributed, small quantities of silk enhance a ruby’s beauty and value by creating a soft uniform distribution of sparkling light.

sixling Rutile twin - Two or more crystals that twin in a repeated pattern ("repeated twinning") as depicted in the figure below. Named after the mineral Rutile, which most frequently exhibits this form of twinning.
Examples of such species include zincite (ZnO), tenorite (CuO), cuprite (Cu2O), rutile (TiO2), uraninite (UO2), corundum (Al2O3), hematite (Fe2O3), and magnetite (Fe3O4).
Star sapphire is the result of reflection of light from fine, oriented, rutile needles. Like star ruby, star sapphires may be heat treated to high temperatures to dissolve the rutile and produce blue sapphires of good clarity.
This phenomenon is caused by very fine needles of rutile. And now and then one of the rare star rubies is found.
Later, sapphire, spinel, rutile, and strontium titanate were grown with this technique. In this process, a single crystal, called a boule, forms in the flame of a simple, downward-impinging oxygen-hydrogen blowtorch.
To help identify an unheated Burma fancy sapphire, try to locate short rutile needles that intersect at 60 degree angles and inclusions that are intact (unexploded).
Genuine Star Rubies are usually not heat treated because heating can dissolve the rutile (silk) which causes the star to form in the first place.
Beware of Synthetic (Lab-made) Star Rubies! Synthetic star rubies jump out as way too perfect looking, i.
If there are no rutile needles within a cabochon sapphire you will only see color and not the phenomenon of a star. Stars have been used in jewelry for as long as sapphires have been cut.
The one essential element needed to produce the star effect is rutile. In corundum (ruby and sapphire), rutile is arranged in densely paced bundles of crisscrossing needles.
"Silk," networks of fine, included rutile needles, intersecting at 60 degree angles, are commonly seen in natural ruby
Included crystals of zircon, and related stress fractures (or halos) are sometimes seen.
Quartz containing large included crystals of rutile or tourmaline is often more valuable than quartz without. Characteristic "horsetail" inclusions are preferred in demantoid.
Gold-colored, hairlike inclusions of rutile (a titanium dioxide mineral) embedded in this gemstone give it the appearance of a frozen meteor shower. The term rutile means "reddish" in Latin.
Sapphire often contains minor inclusions of tiny, slender Rutile needles. When present, these inclusions decrease the transparency of a stone and are known as silk.
rutilated quartz - rutile (roo'til) are needlelike crystals, transparent to opaque brownish to red to black mineral of a higher refractive index than diamond that occurs in a variety of minerals.
Rutilated quartz is transparent rock crystal with golden needles of rutile arrayed in patterns inside it. Each pattern is different and some are breathtakingly beautiful. The inclusions are sometimes called Venus hair.
Rutilate quartz is quartz with a mineral called rutile running through it. Rutile has a high refraction so it appears in long, thin shots of colour.
Clear to opaque shades of yellow, the golden rutile crystals have a near metallic luster. If quartz is heat-treated, which is often done to achieve a more uniform color, then the rutile will burn away.

These rubies contain needle-shape rutile-like inclusions, referred to as silk, that create the illusion of a six-rayed star inside the ruby.
Very fine needles of rutile within the corundum cause this star.Corundum gemstones are the second hardest of the most precious of gemstones.Corundum comes in many colors, and any color other than red is referred to as "sapphire" .

This effect, called asterism, is caused by light reflecting off tiny rutile needles, called "silk," which are oriented along the crystal faces.
"Venus hair stone" is quartz containing needle-like crystals of rutile, and "iris" is quartz that has been crackled within, so as to produce rainbow colors, because of the effects of thin layers of material.
Also found with the rutile needles making a cats' eye or marvelous 6 rayed star when cut en cabochon. Most popular as a blue stone and the most desired are Kashmir sapphires, although they now come from Burma.

Some inclusions decrease the value of a stone, but some, like rutile forming asterisms in star sapphires and needles in rutilated quartz and tourmalated quartz, are prized. The tumbled stones in the photo to the left are tourmalated quartz.
Six-sided asterisms sometimes occur in star sapphires (caused by inclusions of tiny, thin, parallel needles of rutile). Sapphires are related to rubies. Sapphires were once thought to protect the wearer from poisonous creatures.
Inclusions can be solid, liquid, or gaseous. Many inclusions decrease the value of a stone, but some, like rutile forming asterisms in star sapphires and needles in rutilated quartz and tourmalinated quartz, are prized.
