Welcome to SuchenGems!
Sphene, also known as titanite, is a calcium titanium silicate mineral prized for its exceptional "fire" and brilliance, exceeding even that of diamonds. It's known for its wedge-shaped crystals and a range of colors including yellow, green, orange, brown, pink, red, black, and colorless.
Here's a more detailed description:
Composition and Structure:
Chemical Formula: CaTiSiO5 (calcium titanium nesosilicate).
Crystal System: Monoclinic.
Shape: Typically occurs as flattened wedge-shaped crystals or massive forms.
Properties:
Color: Varies widely, including yellow, green, orange, brown, pink, red, black, and colorless. Iron content can influence color.
Hardness: Mohs hardness of 5 to 5.5, making it relatively soft compared to other gemstones like zircon.
Dispersion: One of the highest dispersions of any mineral, meaning it breaks white light into spectral colors, resulting in strong "fire".
Transparency: Can range from transparent to translucent, with jewelry-grade crystals being transparent.
Other: Sphene can exhibit pleochroism (different colors when viewed from different angles) and in rare cases, even color change.
Luster: Resinous to sub-adamantine.
Cleavage: Fair to good on one direction (110).
