Sphene (Titanite) 0.65 CT | Oval Cut Transparent Madagascar
A bright lemon yellow fills this 0.65 carat sphene, also known as titanite. The oval cut is proportioned to show a clear open table, crisp facet junctions and a steady return of light. Transparency is high for the variety with only fine internal features that do not interrupt the view in normal light. Under a lamp the gem shows strong dispersion with small rainbow flashes, a hallmark of fine sphene. Luster is vitreous and the color remains lively in both daylight and indoor light.
Madagascar has become an important modern source of titanite from metamorphic terrains in the central highlands. Production is small scale and irregular, and much rough is either too included or too brown to yield bright faceted stones. Clean crystals that cut into transparent gems of pleasing yellow are uncommon, especially in sizes near one carat. Collectors value sphene for its high dispersion, birefringence that can create a subtle doubling effect, and the distinct chemistry that gives the species its name. This stone represents that limited supply from Madagascar and shows the color and optics that make titanite 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.
