16.52 Ct. Tourmaline from Mozambique

The Natural Gemstone Company is pleased to present a beautiful natural watermelon tourmaline slice, a specimen that captures the classic bi color charm in a transparent and wearable form. This piece weighs 16.52 carat and measures 20.86 by 18.50 by 4.51 mm, offering a substantial presence whether set in jewelry or kept as a collector statement. The shape is slice, with a natural outline and polished faces that reveal the internal color zoning, a vivid pink core encircled by a pale green to near colorless rim. The cut is not applicable for this natural slice form, and the clarity grade is slightly included, evaluated at eye level, which means there are small internal features visible upon close inspection that give character without compromising the gem s overall appeal. Color intensity reads very light, lending a soft and delicate appearance that suits elegant and refined settings. There has been no enhancement, and the origin of this tourmaline is Mozambique, a region respected for producing attractive and ethically minded tourmalines.

As a gem professional I recommend this slice for versatile design approaches because of its transparency, excellent polish, and workable thickness. The 4.51 mm depth provides enough material to set securely in a bezel or in a custom open back mount that allows light to pass through and emphasize the watermelon effect. For rings consider a protective bezel with a minimal gallery to show the color ring, for pendants an open back floating setting will make the pink center glow, and for high end custom objects the slice can be suspended between glass or resin to showcase it as a freestanding display. Slight inclusions add interest and proof of natural formation, and they are not disruptive when the stone is viewed in practical wear situations. Pairing suggestions include warm metals to enhance the pink ring, or cool white metals to let the very light color speak for itself with understated elegance. The natural edge and internal growth features make this slice particularly appealing to collectors who appreciate specimens that show formation history as well as aesthetic beauty.

Care and provenance are important selling points for this piece, and The Natural Gemstone Company stands behind the description and origin. As an untreated natural tourmaline with no enhancements, this slice retains the authentic characteristics that discerning buyers seek, and the Mozambique origin supports traceability and responsible sourcing practices. Cleaning should be gentle, using mild soapy water and a soft brush, avoiding harsh chemicals and extreme heat, and professional jewelers can recommend the best mounting techniques to protect the thinner edges.
