Sphene (Titanite) 0.6 CT | Oval Cut Transparent Madagascar
A bright yellow green tone fills this 0.60 carat sphene, also called titanite. The oval cut shows an open table and well aligned facets with a steady return of light across the face. The body is translucent and displays interesting internal patterns that look like soft bands and feathered veils, a natural record of growth that adds character while the face remains bright. Luster is vitreous and the gemstone shows crisp spectral flashes under a lamp, a hallmark of sphene’s strong dispersion.
Madagascar’s central highlands produce titanite in small artisanal workings from metamorphic terrains. Output is modest and irregular and much rough is too included or leans brown, so lively yellow to yellow green stones suitable for fine faceting are not common. Collectors prize sphene for its high dispersion and noticeable birefringence which can give a gentle doubling of facet edges at certain angles. A gem near this size with attractive color and readable internal patterns is a concise and desirable example of Malagasy sphene.
Fully certified for authenticity and quality, comes with a sensory experience that you won't forget. Don't miss your chance to own this stunning piece of earth wonder.
