Sphene (Titanite) 0.57 CT | Oval Cut Transparent Madagascar
A bright lemon chartreuse tone fills this 0.57 carat sphene. The oval cut shows a clear open table and clean facet junctions with an even return of light across the face. Transparency is good, with tiny internal crystals and fine wisps that add character while the face remains lively. Luster is vitreous and, under a lamp, the gem displays strong dispersion with crisp rainbow flashes that are characteristic of fine titanite.
Madagascar’s central highlands host small artisanal workings in metamorphic terrains that produce titanite in limited quantities. Much rough is either too included or carries a brown cast, so transparent yellow stones of pleasing brightness are not common. Collectors value sphene for dispersion that exceeds diamond and for noticeable birefringence that can softly double facet edges at certain angles. This stone represents that combination of optics and origin that makes Malagasy sphene a sought after specialty gem.
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.
