15.89 Ct. Tourmaline from Mozambique

I am pleased to present a rare and charming watermelon tourmaline slice offered by The Natural Gemstone Company, a specimen that blends natural beauty with collector appeal. This transparent slice weighs 15.89 carat, and measures 21.26 x 18.66 x 4.01 mm, showcasing an appealing thin profile that makes it ideal for both display and creative jewelry design. The slice shape preserves the crystal as it was formed, and the piece displays a soft pink core surrounded by a pale green rim that is characteristic of classic watermelon tourmaline. The color intensity is very light, which gives the stone a delicate pastel appearance when viewed face on, and the clarity is graded slightly included evaluated at eye level, which means natural internal features are visible but do not overpower the gentle color zoning. The surface has received an excellent polish, allowing light to pass through and accentuate the inner color zones, and importantly this tourmaline has no enhancement, preserving its natural origin and character from Mozambique.

From a gemological perspective this slice offers several attractive attributes that make it desirable for collectors and designers alike. The transparency and thinness allow for a degree of translucency that highlights the concentric color zoning, and the very light pink center transitioning to a pale green edge creates a soothing and visually balanced contrast. Slight inclusions are present when viewed at normal viewing distance, and these internal characteristics tell the story of the stones natural growth, adding to its authenticity and charm. The excellent polish enhances the appearance by creating a smooth reflective surface that intensifies the gentle color shift without obscuring the natural features. Because there has been no enhancement, the color and clarity are entirely natural, which is a key consideration for buyers who value untreated gemstones. The Mozambique origin further contributes to the appeal, as East African mines have become known for producing attractive tourmaline material with pleasing hues and interesting crystal habits.

In terms of practical use and styling ideas this watermelon tourmaline slice is exceptionally versatile. Its modestly thin profile of 4.01 mm makes it an excellent candidate for a custom pendant with an open back setting to allow light to enter, a bezel mounting that emphasizes the slice silhouette, or a framed display as a focal piece in a collectors cabinet. Paired settings that let the light interact with the stones natural zoning will showcase the soft pink core and pale green halo to best effect. For designers who prefer a contemporary look, a minimalist mount in warm metal tones will complement the pastel colors, while a white metal setting will lend a crisp contrast that emphasizes the delicacy of the hues. Because the material is natural and unenhanced, standard care recommendations apply. Clean with warm soapy water and a soft brush, rinse thoroughly, and avoid harsh chemicals and repeated thermal or mechanical shock to protect the stone and the natural inclusions that make each slice unique.

At The Natural Gemstone Company we pride ourselves on sourcing distinctive natural gemstones that reflect authentic origin and minimal intervention, and this Mozambique watermelon tourmaline slice is a fine example of that commitment. Its combination of 15.89 carat weight, transparent slice form, very light pastel color intensity, slightly included clarity evaluated at eye level, and excellent polish with no enhancement makes it a compelling acquisition for collectors, bespoke jewelers, and anyone seeking a gentle and natural color statement. Availability of such well preserved slices is limited, and we recommend contacting our sales team for additional photos, custom mounting options, and any certification requests.
