Sphene (Titanite) 0.66 CT | Oval Cut Transparent Madagascar
A bright lemon yellow fills this 0.66 carat sphene, also known as titanite. The oval cut is well proportioned with an open table and clean facet junctions that return a steady, lively brilliance. Transparency is good and the luster is vitreous. Small internal crystals and fine wisps create unique inclusions that are visible under the table and serve as a natural fingerprint while the face remains bright. Under a lamp the gem shows strong dispersion with crisp rainbow flashes that sphene is prized for.
Madagascar’s central highlands host metamorphic terrains that produce titanite in small artisanal workings. Output is irregular and much rough is too included or too brown to cut into bright yellow gems, which keeps clean stones in short supply. Collectors value sphene for its high dispersion and noticeable birefringence that can give a subtle doubling of facet edges. Transparent yellow pieces near one carat from Madagascar are uncommon, and those with distinctive yet attractive inclusions are particularly desirable for their individuality and clear link to origin.
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.
