The crystals will always form according the geometric parameters of the mineral crystal system to which they belong, but the size of the crystals varies depending on the environment in which they form.
Tourmaline crystals can have a streak that ranges from white to colorless. The streak of a tourmaline mineral is usually lighter than its external color.
No, the crystals of a mineral can vary in size depending on factors such as growth conditions and the speed at which the mineral forms. Crystals can range from microscopic to very large sizes, even within the same mineral species.
Stibnite is a sulfide mineral that has long metallic slender bladed crystals. It often has a shiny, silvery-gray color and is commonly found in hydrothermal veins. Stibnite is composed of antimony sulfide and is used in the production of antimony metal.
Basalt is a fine-grained volcanic rock, usually dark in color, while gabbro is a coarse-grained intrusive rock that is also dark in color. Basalt tends to cool and solidify quickly on the Earth's surface, resulting in a fine-grained texture, whereas gabbro cools slowly beneath the surface, allowing larger mineral crystals to form.
No. It can vary from the visible color of the mineral and, since visible color of them ineral is not a reliable indicator of type, it is important to learn to use streak, (along with other factors), to correctly identify a mineral.
Crystals have regular, flat faces that form at very specific angles to each other and reflect their atomic structure. To identify what type of mineral you have, consult mindat.org, or a library, or a university earth science department, a local museum with mineral exhibits, or a local mineral collecting club.
What mineral that appears in transparent hexagonal crystals
The arrangement of atoms in a mineral sample can cause the formation of crystals.
Amethyst crystals are a type of quartz mineral that is typically purple in color due to trace amounts of iron in the crystal lattice. They are prized for their vibrant color and are often used for jewelry and decorative purposes.
The crystals will always form according the geometric parameters of the mineral crystal system to which they belong, but the size of the crystals varies depending on the environment in which they form.
Gemstones are made from mineral crystals, yes.

No, the crystals of a mineral can vary in size depending on factors such as growth conditions and the speed at which the mineral forms. Crystals can range from microscopic to very large sizes, even within the same mineral species.
It could be any number of minerals such as biotite mica, or hornblende.
