A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are about 5900 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The silicates are the most abundant and chemically complex group of minerals. All silicates have silica as the basis for their chemistry. "Silica" refers to SiO2 chemistry. The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4. Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens "belong" to each silicon. The resulting formula for silica is thus SiO2, not SiO4.
The simplest & most abundant silicate mineral in the Earth's crust is quartz (SiO2). All other silicates have silica + impurities. Many silicates have a significant percentage of aluminum (the aluminosilicates).
Quartz (silicon dioxide/silica - SiO2) is the most common mineral in the Earth's crust. It is composed of the two most abundant elements in the crust - oxygen and silicon. It has a glassy, nonmetallic luster, is commonly clearish to whitish to grayish in color, has a white streak, is quite hard (H≡7), forms hexagonal crystals, has no cleavage, and has conchoidal fracture. Quartz can be any color: clear, white, gray, black, brown, pink, red, purple, blue, green, orange, etc.
The white coloration of milky quartz is attributed to the presence of abundant microscopic fluid inclusions.

Le quartz est une espèce minérale du groupe des silicates, sous-groupe des tectosilicates, composé de dioxyde de silicium de formule SiO2 (silice), avec des traces de différents éléments tels que Al, Li, B, Fe, Mg, Ca, Ti, Rb, Na, OH. La citrine est une variété de quartz, dont la couleur jaune est due à la présence d'infimes quantités d'oxydes de fer dans le minéral. La citrine se trouve assez rarement à l'état naturel. Le plus souvent il s'agit d'améthyste chauffée qui prend une couleur jaune au lieu de violette. (Wikipedia)

A 50 carat bicolor quartz - clear and yellow. According to the dealer, this is from a find in Bolivia a few years ago. I bought it at the AGTA show in Tucson. I was having DOF issues with this picture; the light was low, I took it without a tripod, so I had to open up the aperture. It's a big enough stone that it ended up not all in focus.

Golden Rutilated quartz is also purported to enhance mental and physical stability, self-reliance, and meditation on feminine ideas.
It is reputed to diminish issues with decision-making by enhancing one's understanding in difficult situations, thus facilitating timely and appropriate solutions.
It is also said to relieve depression and loneliness, and to help provide new direction and enhance creativity.
Rutilated quartz is also used metaphysically to deflect negative energies and unwanted energetic, psychic, and magical interferences.
Rutilated quartz is said to assist with tissue regeneration, assimilation of nutrition, and slow the advancement of aging.
It is also said to boost the immune system and treat respiratory illness. Rutilated quartz is said to slow down the aging process and to help strengthen the immune system. It is also said to be a strong healer and to be helpful in recovering from radiation exposure.
Physically, rutilated quartz is said to be beneficial for food disorders, the immune system, regeneration of tissue, fatigue, depression, respiratory illness, stability of all physical systems and general health, and absorption of nutrients from food. It is also reputed by intuitive sources to be helpful for getting energy moving in meridians and areas where the physical energy is sluggish. Rutiliated quartz is also a mystical crystal "diagnostic tool" which can help discover the true cause of an ailment.
