Corundum crystals belong to the ditrigonal-scalenohedral class of the trigonal symmetry D63d - R 3-C(L33L23PC) with symmetry elements:
• Mirror-turn axis of the sixth order (ternary inversion axis)
• Three axes of the second order normal to it
• Three symmetry planes normal to the axes of the second order and intercrossing
along the axis of the highest order
• Symmetry center

What crystal has six sides?
Graphite is an example of a hexagonal crystal. Beryl also forms a six sided crystal.Magnesium exhibits close packed hexagonal crystal structure.
What word describes the first particles of a crystal that form a three dimensional pattern?
The word that describes the first particles of a crystal that form a three-dimensional pattern is "nucleus." In crystallization, the nucleus serves as the initial site around which additional particles arrange themselves, leading to the growth of the crystal structure. This process is crucial for the development of ordered crystalline materials.

Why nickel face is two directions?
Nickel has two faces, or crystallographic orientations, due to its face-centered cubic (FCC) structure. This structure allows for multiple equivalent arrangements of atoms in the crystal lattice, leading to distinct planes of symmetry. As a result, nickel can exhibit different surface properties and behaviors depending on the direction of the crystal face being examined, which is important in applications such as catalysis and materials science.
Do sapphires come in red?
No, sapphires are typically blue in color. Red sapphires are actually a specific type of corundum called rubies. Rubies are red due to the presence of trace elements like chromium in their crystal structure.
What is the sapphires crystal shape?
a oval
What is it that makes sapphires blue?
Sapphires are blue because of the presence of trace elements, mainly iron and titanium, in their crystal structure. These elements absorb certain wavelengths of light, causing the sapphire to appear blue to the human eye.
Where makes sapphires blue?
The blue color of sapphires primarily comes from trace amounts of iron and titanium within the corundum crystal structure. When aluminum oxide (the main component of sapphires) incorporates these elements during its formation, it alters the way light interacts with the crystal, resulting in the characteristic blue hue. Additionally, the specific shade of blue can vary based on the concentration of these trace elements.
Why are sapphires blue in color?
Sapphires are blue in color due to the presence of trace elements, specifically iron and titanium, in their crystal structure. These elements absorb certain wavelengths of light, causing the sapphire to appear blue to the human eye.
What is the texture of a sapphire?

What is the crystal structure for silver?
There is no crystal structure.
Dose malachite have a crystal structure?
Yes, the mineral malachite does have a crystal structure.
What is the crystal structure of beryllium?
Beryllium's crystal structure is hexagonal.
What is the crystal structure of phosphorous?
The crystal structure of phosphorous is monoclinic.
What is the crystal structure of fermium?
The crystal structure of fermium was not determined.
What are sapphires formed from?
Sapphires are formed when heat and pressure are applied to the mineral corundum. A sapphire can be any color but red. Impurities introduced in to the corundum during crystal formation dictate the final gemstone color.
