The name "sphene" comes from the Greek word, "sphen", meaning "wedge", which alludes to the formation of its crystals. Due to its high dispersion, when brilliant-cut, sphene can exhibit a fire similar to that of diamond. Sphene has been known since 1787 and was named according to its titanium content in 1795 by Martin Klaproth. In 1801, it was given the name "sphene" by French mineralogist, Rene Just Hauy. In 1982, the International Mineralogical Association Commission on New Minerals and Mineral Names (CNMMN) decided to use the name "titanite" rather than "sphene". However, both "sphene" and "titanite" continue to be recognized in mineralogy circles, and sphene is the most frequently used gemology term. Lore Sphene Gemstone Mythology, Metaphysical and Alternative Crystal Healing Powers Back to Top Sphene is said to be a calming and soothing stone that protects its wearer from negative energy. Additionally, sphene is thought to aid clear thinking and creativity. In traditional Hindu belief systems, sphene is associated with the Ajna chakra; also known as the third eye, or brow chakra, which is related to the mind and previous lives. Physically, sphene is thought to help alleviate muscle strain, fever and tissue inflammation.
