The "Same Piece" Phenomenon: Color Zoning
The fact that all three slices came from the same crystal is the most scientifically interesting and aesthetically pleasing aspect of your set.
· How it Happens: Tourmaline is a complex mineral (a boron silicate) whose color is determined by trace elements like iron, manganese, lithium, and others. As the crystal grew in the pegmatite (a very slow-cooling, fluid-rich igneous rock), the chemical composition of the feeding solution changed.
Afghanistan, particularly the Nuristan and Kunar provinces, is world-renowned for producing some of the finest and most colorful tourmalines on the market.
Pink/Red to Green: The most classic "watermelon" pattern, but often the slices are purely pink or purely green if cut from the respective zones.
· Blue (Indicolite) to Green: A rarer and highly prized combination.
. Slices vs. Gems: These are polished slabs, not faceted gems. Their value lies in their display of the internal structure and color zoning.
· Purpose: They are perfect for:
· Collectors: As a scientific and beautiful specimen.
· Jewelry Designers: They can be set in unique, one-of-a-kind jewelry
