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 is another name for crystal shapes?
crystallographic structure
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.
A solid with flat sides that meet at sharp edges and corners is called?
a solid with flat sides meet at sharp edges and corners is called crystal structure
How many sides does a crystal have?
The number of sides a crystal has depends what minerals or elements make up the crystal. A cubic crystal has 6 sides. A hexagonal crystal with flat ends has 8. A hexagonal crystal with pointed ends has 18.
Which is the hardest mineral?
Diamond is the hardest mineral at Mohs hardness 10, ten being the hardest. There is no natural mineral substitute for processes requiring diamond. Diamond is four times as hard as corundum, the mineral constituting rubies and sapphires. Although diamond is the hardest naturally occurring mineral, it is easily fractured, a characteristic which allowed early jewellery makers to facet this crystal.
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 the texture of a sapphire?
hard a heck
What is the crystal structure for silver?
There is no crystal structure.
Dose malachite have a crystal structure?
Yes, malachite does have a crystal structure. It belongs to the monoclinic crystal system.
What is the crystal structure of fermium?
The crystal structure of fermium was not determined.
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 does definite crystal structure mean?
a crystal structure is a turtle in disguise
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.
What is radium's crystal structure?
The crystal structure of radium is cubic, body-centered.
Do both diamond and graphite have a crystal structure?
Yes, both diamond and graphite have a crystal structure. Diamond has a cubic crystal structure, while graphite has a hexagonal crystal structure.
