14.23 Ctw 50/50 Split Bi-Color Blue-Green Tourmalines from Mozambique

This very rare set of tourmalines was mined in Mozambique about 15 years ago.  They have a perfect split directly in the middle of each tourmaline with one side being a lagoon blue and the other a vivid green.  The split is not included or fractured like the vast majority of bi-colors you see out there, these are both eye clean stones.  The bar cut on these creates a very neat optical effect that pixilates the blues and greens creating many beautiful blends of the two colors.
