Sphene, also known as titanite, is a fascinating gemstone renowned for its exceptional brilliance and dispersion, which is even greater than that of diamond. It typically exhibits a range of colors, including green, yellow, brown, and sometimes even colorless, with an intriguing play of colors due to its high refractive index.

In terms of hardness, sphene has a rating of about 5 to 5.5 on the Mohs scale, making it relatively softer than many other gemstones. This means it requires careful handling to avoid scratches and damage. Sphene often contains inclusions, which can include needle-like crystals, and these inclusions can add to the stone's unique beauty.

Metaphysically, sphene is believed to enhance mental clarity, creativity, and intuition. It's also thought to promote positive energy and help with decision-making. Overall, sphene is a captivating gemstone with striking visual properties and meaningful metaphysical associations.
