Specular iron (/ˈspɛkjʊlər ˈaɪərn/) is a type of high-quality iron ore that has a reflective or mirror-like appearance. The word "specular" comes from the Latin word "speculum," meaning mirror. The spelling of the word "specular" can be explained using the International Phonetic Alphabet (IPA): the first syllable contains the vowel sound /ɛ/ (as in "bed"), followed by the consonant cluster /kj/ (as in "key"), and the second syllable contains the vowel sound /ʊ/ (as in "put") and the consonant /l/ (as in "all").
Specular iron refers to a type of iron ore that possesses a distinctive metallic luster and a mirror-like appearance when polished or exposed to light. It is also commonly known as specular hematite due to its characteristic red coloration.
In terms of composition, specular iron is primarily composed of hematite (Fe2O3), which is an iron oxide mineral. It typically forms in sedimentary environments and can be found in various parts of the world. The name "specular" is derived from the Latin word "speculum," meaning mirror, which aptly describes the reflective nature of this iron ore.
Specular iron is often used as an important ore in the production of iron and steel. Its high iron content makes it an attractive option for extraction and smelting. Due to its unique properties, such as its exceptional reflectivity and metallic luster, it is also highly sought after in jewelry and ornamentation.
The distinctive mirror-like appearance of specular iron makes it an intriguing material for both industrial and aesthetic purposes. Its striking visual appeal has made it a popular choice for ornamental items, including beads, pendants, and decorative objects. Furthermore, its reflective properties have been utilized in industry as a component in certain optical and scientific instruments.
In summary, specular iron is a variety of iron ore that stands out for its characteristic metallic luster, mirror-like shine, and red coloration. It is primarily composed of hematite and finds applications in the production of iron and steel, as well as in jewelry and ornamentation.

The term "specular iron" combines two words: "specular" and "iron".
The word "specular" originates from the Latin word "speculum", which means "mirror" or "reflection". It is derived from the verb "specere", meaning "to look" or "to see". "Specular" describes something that reflects light or has a shiny, mirror-like surface.
On the other hand, "iron" comes from the Old English word "īren", which also has its roots in the Proto-Germanic word "īsarną". This term has cognates in other Germanic languages, such as the Old Norse "jarn" and the German "Eisen", all representing the metal known as iron.
When combined, "specular iron" refers to a particular type of iron known for its bright, reflective surface, resembling a mirror.
