Bi-color Blue Purple Indicolite Tourmaline 1.80 CT Emerald Cut | Mozambique
A cool gradient moves through this 1.80 carat tourmaline, shifting from steel blue to soft purple along the length of a clean emerald cut. The steps are even and well aligned, giving a bright, orderly return of light that makes the zoning easy to read. Luster is vitreous, transparency is high, and the color remains stable in daylight and indoor light.
This is elbaite from Mozambique, a source known for fine blue tourmaline traditionally called indicolite. The indicolite effect refers to blue color caused by iron in the crystal combined with tourmaline’s strong pleochroism, which makes the blue appear deeper as the stone is turned or viewed along different directions. The presence of a second growth zone influenced by manganese introduces a distinct purple segment, creating a blue to purple bi-color that is far less common than green to pink combinations. Clean stones near two carats that display a clear blue segment together with a true purple zone are scarce, which places this piece among the rarer color expressions of Mozambican tourmaline.
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.
