Sphene, also known as titanite, is a rare and brilliant gemstone prized for its exceptional fire—its ability to split light into dazzling rainbow flashes that rival even diamonds. Its name comes from the Greek word sphenos, meaning wedge, a nod to the crystal’s typical shape.

Sphene’s most common color is a vibrant greenish-yellow, though it can also appear in shades of brown, orange, or green. What makes sphene truly unique is its high dispersion and distinct pleochroism, meaning it can show different colors from different angles. This optical performance, paired with a slightly softer hardness of 5 to 5.5 on the Mohs scale, makes it a collector's gem more than an everyday wear stone.

Chemically, sphene is a calcium titanium silicate and is often found in metamorphic rocks. Its rarity, brilliance, and fiery sparkle make it a favorite among gem enthusiasts and those seeking something a little different from traditional gems.
