This piece has outstanding aesthetics . When slightly backlighted its intense blue phantoms just glow contrasting with the lighter coloured and matt rhombododecahedron faces. Luster is good, especially for the largest crystal, however the left side crystal has matt appearance probably caused by late mineralization fluids. Condition is excellent with only one millimetre ding and a natural conchoidal fracture at the lower crystal. This completely floater specimen was covered at the back with amorphous calcite, recently carefully removed to show better its gemminess.
