Sphene

Sphene, also known as titanite, is a rare and striking gemstone prized for its exceptional brilliance and vivid dispersion, surpassing even that of diamonds. It typically exhibits a rich green, yellow, or brown hue, often with a captivating play of colors due to its high refractive index. Sphene's name derives from the Greek word "sphen," meaning wedge, referencing its crystal shape. Found in regions like Brazil, Pakistan, and Madagascar, this gemstone is also valued by collectors for its unique crystal structure and significant titanium content. Despite its beauty, sphene's relative softness requires careful handling in jewelry.
