Liddicoatite Tourmaline Slice
Anjanbonoina, Antananarivo Prov., Madagascar
42 cm tall x 28 cm wide
Liddicoatite is a rare member of the Tourmaline family, identifiable by their exotic internal geometric patterns. Liddicoatite tourmalines are commonly sliced and polished to reveal their multitude of colors, and what is known as "The Mercedes" symbol hidden at the center of every crystal. Liddicoatite crystals are mainly found in Madagascar, named in honor of Richard T. Liddicoat (1918–2002), gemmologist and president of the Gemological Institute of America.
This slice is considered the largest fine Liddicoatite ever found. Its size is enormous for the species. It is one of three that came from the same crystal - actually two large crystals in parallel growth.
The central focus is an elongated, oval-like shape with a rich, deep pink core. Surrounding the core is a lighter pink hue that transitions into a white band, which contrasts with the outer layer of the piece composed of a dark, almost black color. The bottom crystal has the cranberry red color of a Rubellite Tourmaline while the upper crystal has the more classic Liddicoatite structure.
The combination of colors highlighted by natural fractures and patterns add depth and complexity.
The stark black outline enveloping the composition adds a sense of containment and finality, framing the inner vibrancy with a profound contrast that is both striking and contemplative. For any sliced mineral it is imperative that this edge is complete, or intact. This slice has a perfect edge, rich strong colors, and mammoth size, placing it well beyond all other examples.
