It is a calcium titanium silicate with a refractive index of 1.885–2.050 and a dispersion value of 0.051 — higher than diamond (0.044). This gives faceted sphene its characteristic fire and color play. Madagascar is one of the primary sources for gem-quality sphene with strong green hues.\u003c\/p\u003e\n\u003ch3\u003eSuitability\u003c\/h3\u003e\n\u003cp\u003eDue to its relatively lower hardness (5–5.5 on the Mohs scale), sphene is best suited for pendants, earrings, brooches, and collector settings rather than rings or high-wear jewelry. It is a collector-grade stone and a recognized May birthstone alternative.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs sphene a durable stone for everyday jewelry?\u003c\/strong\u003e\u003cbr\u003e\nSphene has a Mohs hardness of 5–5.5, making it more suitable for low-contact settings like pendants and earrings.
