Sphene, also known as titanite
Sphene has rich body colors, strong trichroism, and a fire that exceeds diamond. Although softer than many more popular gems, sphenes can make wonderful jewelry stones if set and maintained properly. Chrome sphene is the most valuable type. The chrome sphene from Baja California is the color of fine emerald and very rare, especially if clean and larger than 1 carat. Brazilian yellow gem material has a sleepy look and isn’t as bright as that from Baja. Some of the largest and most spectacular green gems have been cut from Indian material. Sphene is usually included and rarely even eye clean. Sphene’s relatively low hardness (5 to 5.5) and distinct cleavage make it a risky choice for jewelry. However, it also possesses gemological properties that make it a desirable piece for collectors as well as adventurous jewelry enthusiasts. For example, sphene’s dispersion or fire ranks among the highest in the gem world. However, its body color, degree of inclusions cutting orientation, and cutting style may enhance or obscure this feature. (Gems with high dispersion and strong pleochroism like sphene may not show both properties at the same time). Never use mechanical cleaning systems such as steamers or ultrasonics. Clean sphenes only with a soft brush, mild detergent, and warm water.
