What mineral is a hard abrasive?
Corundum - Crystalline Aluminium Oxide (Al2O3) is a mineral that is hard (9.0 on Mohs scale) and used as an abrasive.
A hard colorful mineral with a brilliant luster or color?
Could be diamond, ruby, emerald, tourmaline.
Which property best describes a piece of quartz?
It is a hard crystalline compound of silicon and oxygen.
Is igneous rock generally soft or hard rock?
Igneous rock is generally hard rock because it forms from the solidification of molten magma below or at the Earth's surface, resulting in a crystalline structure that is dense and strong. However, the hardness can vary depending on the specific mineral composition and cooling history of the rock.
Can an emerald be scratched by a fingernail?
No, emeralds are relatively hard gemstones, ranking 7.5-8 on the Mohs scale of mineral hardness, while a fingernail ranks around 2-2.5. This means that an emerald should not be easily scratched by a fingernail.
How does a garnet feel?
A garnet is a hard, crystalline mineral. In nature it is usually rough and jagged, but it can be polished for use in jewelry
What is a six sided mineral crystal a very hard mineral called?
A six-sided mineral crystal that is very hard is typically referred to as a hexagonal crystal. One common example of a hard mineral with this crystal structure is quartz, which has a hardness of 7 on the Mohs scale. Another example is beryl, which includes varieties like emerald and aquamarine. These minerals are characterized by their distinct six-sided (hexagonal) symmetry and exceptional durability.
What type of rock is an emerald?
Emerald is a form of the mineral beryl. It is typically found in metamorphic or igneous rocks, such as mica schist or granite. The green color of emerald comes from trace amounts of chromium or vanadium in the crystal structure.
What is a very hard native crystalline carbon valued as a gem?
Diamond is a very hard native crystalline carbon valued as a gem
What comes in many forms and is hard like a rock?
Minerals can come in a variety of forms and are naturally occurring solids that have a characteristic crystalline structure. Minerals like quartz and diamond are examples of hard minerals that can be mistaken for rocks due to their physical properties.
Is a white mineral that is very hard?
Diamond is a very hard white mineral.
What is the complete definition of mineral?
A mineral is a naturally occurring inorganic solid with a specific chemical composition and a crystalline structure. Minerals can be identified by their physical properties, such as color, hardness, and cleavage. They are the building blocks of rocks and are formed through geological processes.
