4.12 Ct. Tourmaline from Mozambique

This transparent watermelon tourmaline is a precise collector grade specimen, weighing 4.12 carats, with dimensions 14.28 x 11.34 x 2.42 mm, slice shape, cut n a, and excellent polish. The piece displays classical boreal zoning, with a concentrically saturated pink core transitioning to a very light green peripheral bodycolor, presenting a very light color intensity overall. Clarity is graded slightly included, evaluated at eye level, with fine needle and liquid inclusions that are typical of Mozambique tourmaline and that serve to verify natural origin rather than detract from visual appeal. No enhancement has been applied, and the original crystal surfaces have been preserved in the slice format to retain natural growth features and termination character where present.

From a gemological and lapidary perspective this slice offers important technical advantages for designers and specialists, including a broad window for light transmission, stable polish response on flat planes, and predictable cleavage orientation for secure bezel or inlay settings. Optical characteristics are consistent with elbaite tourmaline, including refractive index in the typical range for tourmaline, notable pleochroic variation between the pink and green zones, and a specific gravity that aligns with Mozambique sourcing. The slightly included clarity, when observed at eye level, enhances internal contrast and delineation of the pink core without compromising transparency, making the color zoning particularly legible under standard jewelry lighting. For mounting considerations we recommend protective settings that support the thin profile, such as bezel, flush inlay, or custom micro mountings that minimize edge exposure while showcasing the concentric color targeting. This specimen from Mozambique is offered by The Natural Gemstone Company, presented as a natural, untreated slice ideal for collectors, connoisseurs, and designers seeking authentic watermelon tourmaline material with clear provenance and technical integrity.
