Nat Sphene/Titanite From Madagascar 1.00 CT
Madagascar is one of the world's premier sources for natural sphene (also known as titanite). The region is highly prized by gem collectors and jewelers for producing exceptionally clear, vivid green, golden-yellow, and brown crystals that frequently exhibit large sizes.
Key Characteristics of Madagascar Sphene
- Exceptional Fire: Sphene is renowned for its extreme dispersion (its ability to split light into rainbow flashes), which is even higher than a diamond.
- Color Palette: Madagascar material is uniquely celebrated for its lush, vibrant green stones (often compared to chrome tourmaline or tsavorite) and rich, golden-yellows.
- Size: Unlike localities such as Brazil where sphene is typically under 5 carats, Madagascar yields larger roughs, allowing for 10-carat or larger faceted gems.
Gemological Properties
- Composition: Calcium Titanium Silicate
- Hardness: 5.0 to 5.5 on the Mohs scale. Because it is relatively soft, it is best suited for earrings or pendants rather than daily-wear rings.
