Emeralds have a hardness of around 7.5-8 on the Mohs scale, so minerals with a higher hardness like corundum (9) and diamond (10) can scratch emeralds. Minerals with a lower hardness, such as quartz (7) and feldspar (6), would not be able to scratch an emerald.
Diamonds are proven to scratch all minerals including itself.
Minerals that can scratch apatite include fluorite, quartz, topaz, and corundum. These minerals have a higher hardness level than apatite on the Mohs scale, which allows them to scratch apatite.
A steel file can scratch minerals with a hardness of 6.5 or lower on the Mohs scale. This includes minerals such as gypsum, calcite, and fluorite.
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
The scratch table is called the Mohs Scale of Mineral Hardness and measures the hardness of minerals in relation to the known hardest (diamond) and softest (talc) minerals.
Emeralds are not actually rocks, but minerals of the beryl family that have gemstone qualities.
Diamonds are proven to scratch all minerals including itself.
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
Malachite is also green.
Minerals that can scratch apatite include fluorite, quartz, topaz, and corundum. These minerals have a higher hardness level than apatite on the Mohs scale, which allows them to scratch apatite.
A steel file can scratch minerals with a hardness of 6.5 or lower on the Mohs scale. This includes minerals such as gypsum, calcite, and fluorite.
Talc is the softest mineral on the Mohs scale with a hardness of 1, so it can be easily scratched by harder minerals. Talc can scratch over minerals with a lower hardness value, but it cannot scratch minerals that are harder than itself, such as quartz or diamond.
Emeralds are essentially just gem quality beryl's. Another sort of beryl used in jewelry and by gem collectors is aquamarine. Emeralds also fit the criteria of minerals, being inorganic, solid, crystalline, naturally occurring, and having a well defined chemical composition.
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
Emerald is a mineral. Specifically, it is a variant of the mineral known as beryl.
Kimberley is renowned for diamonds, but there are gold and emeralds there too.
Any mineral with roughly a hardness of 6 or more on the Mohs scale of mineral hardness could scratch glass, which is roughly 5.5 on the Mohs scale. Some minerals that could scratch glass would be quartz, topaz, corundum, and diamond.
