, also known as titanite, is a brilliant and rare gemstone prized for its exceptional fire—dispersion even greater than that of diamond. Typically found in hues of green, yellow, brown, or even reddish tones, sphene owes its rich colors to traces of iron and rare earth elements. Its strong pleochroism allows it to display different colors when viewed from different angles, adding to its visual intrigue. With a hardness of 5 to 5.5 on the Mohs scale, it is more suitable for jewelry worn occasionally or in protective settings. Sphene’s vibrant sparkle and unique optical properties make it a collector’s favorite and a striking choice for distinctive jewelry.
