Sphene, also known as titanite, is a fascinating gemstone known for its exceptional brilliance and fire. It has a high refractive index, which means it can exhibit a lot of sparkle and colorful flashes of light. Sphene typically comes in shades of green, yellow, and brown, but can also be found in colorless varieties.

One of its most notable characteristics is its strong pleochroism, which means it can show different colors when viewed from different angles. This can make it quite captivating in jewelry. However, sphene is relatively soft compared to other gemstones, with a hardness of about 5 to 5.5 on the Mohs scale, which means it requires careful handling to avoid scratches.

If you're interested in its metaphysical properties, sphene is said to promote creativity and enhance one's ability to manifest their desires. It's a unique stone that can be a great addition to any gemstone collection!
