Top best answers to the question «Is iolite the same as cordierite»

"Cordierite" is a name used by geologists. When the mineral is transparent and of gem quality, it is known as "iolite" in the gem and jewelry trade. Two older names for the mineral are "dichroite" and "water sapphire." The name dichroite means "two-color rock," inspired by cordierite's pleochroic property.

FAQ

Those who are looking for an answer to the question «Is iolite the same as cordierite?» often ask the following questions:

✨ How is cordierite different from corundum and iolite?

  • Can be distinguished from corundum by its lower hardness Cordierite ( mineralogy) or iolite ( gemology) is a magnesium iron aluminium cyclosilicate.

✨ What is the difference between cordierite and iolite?

  • Iolite: Gem-quality cordierite and blue sapphire look-alike. Cordierite is the mineral known as "Iolite" when it is of gem quality. Iolite: A blue-violet iolite faceted from material mined in Madagascar.

✨ What is the formula for iolite and cordierite?

  • Cordierite. Cordierite ( mineralogy) or iolite ( gemology) is a magnesium iron aluminium cyclosilicate. Iron is almost always present and a solid solution exists between Mg-rich cordierite and Fe-rich sekaninaite with a series formula: ( Mg, Fe) 2Al3 ( Si5AlO18) to ( Fe, Mg) 2Al3 ( Si5AlO18 ).

Whether or not the tales are true, iolite (mineralogists call it cordierite) can be fashioned into beautiful gems. Strongly pleochroic iolite has been incorrectly called “water sapphire,” as it can display a blue to violet hue in one direction and pale yellow to colorless in another. Iolite Description.

The mineral Cordierite has a gem variant called iolite. Iolite ranges in color from light to dark blue, with a purple tint. Stones with a deeper hue are more expensive. Iolite is a low-cost, long-lasting blue gemstone that may be used to replace more costly blue gemstones like Sapphire. Is cordierite a mineral or a ceramic?

Cordierite (mineralogy) or iolite (gemology) is a magnesium iron aluminium cyclosilicate. Iron is almost always present and a solid solution exists between Mg-rich cordierite and Fe-rich sekaninaite with a series formula: (Mg, Fe) 2 Al 3 (Si 5 Al O 18) to (Fe, Mg) 2 Al 3 (Si 5 Al O 18).

Geologists & mineralogists refer to iolite as cordierite, and in the past, the mineral has also been termed dichroite. Cordierite, typically is found in the vicinity of other alumino-silicates, such as andalusite, kyanite & sillimanite, within amphibolite-grade metamorphic complexes. Host rocks include alumina-rich mica schist (metapelite).

The simple answer to this question is yes. Cordierite is the official name of the mineral. Iolite is the commercial name of the stone and "water sapphire" is an alternative name given to the stone. .

Overall, Iolite appears as violet-blue or indigo, but in different positions may shift to a yellow-gray or honey color, and even to a clear light blue. It is also referred to as “Water Sapphire” or Dichroite. Iolite’s name comes from the Greek ios, meaning violet, and is the gem version of the mineral Cordierite.

How are sekaninaite and cordierite the same mineral?
  • Cordierite forms a solid solution series with the rare mineral Sekaninaite. Cordierite is the magnesium-rich end member, and Sekaninaite is the iron-rich end member. Pure Cordierite without any iron present is not common. Cordierite often is replaced by other minerals, especially phyllosilicates such as micas, Chlorite, and Talc.
