1.69 Ct. Tourmaline from Mozambique

This 1.69 carat watermelon tourmaline from Mozambique is a rare and beautiful example of natural color zoning, presented as a transparent slice with dimensions of 8.09 by 7.88 by 3.08 mm, and an excellent polish that maximizes its visual appeal. This piece displays the classic watermelon configuration, a vivid pink core surrounded by a lively green rim, rendered here at a medium intense color intensity that balances saturation with clarity, allowing light to pass through the stone and reveal the layered hues. The cut is not applicable in the conventional faceted sense, because this is a slice, yet the finishing polish is excellent, which is a decisive advantage over many raw or poorly finished slices on the market. Clarity is graded included, evaluated at eye level, which means there are internal features that are visible and that reinforce the natural character and provenance of the gem, rather than detracting from it. The stone has received no enhancement, it is untreated and natural, which is an increasingly rare quality in tourmalines and a strong point for collectors and connoisseurs who seek authenticity and long term value.

When you compare this watermelon tourmaline to other options available on the market, several important differences emerge, differences that make this offering from The Natural Gemstone Company stand out. Many commercially available watermelon tourmalines are small, heavily included, or have been subjected to treatments such as heat, irradiation, or dyeing to intensify colors and improve marketability. Treated stones may look striking at first glance, but their color can be unstable and their long term value is compromised. This Mozambique slice, by contrast, is naturally colored, untreated, and transparent enough to show the interplay of pink and green while retaining the characteristic inclusions that certify its natural origin. Other sources of watermelon tourmaline, such as some Brazilian or Madagascan material, may produce strong colors but often require cutting and polishing that reduces the distinctive heart like pattern seen in genuine slices. Here, the combination of medium intense color, transparency, and an excellent polish preserves the natural pattern and offers a piece that is equally suited to collectors who prize authenticity and designers who need a striking natural focal point.

From a practical and design perspective, this slice shape watermelon tourmaline offers advantages over both faceted tourmalines and rough mineral slices. Faceted stones can deliver flash and brilliance, but they rarely preserve the concentric zoning that makes watermelon tourmaline memorable, and faceting can result in significant weight loss from the original crystal. Rough slices can show the zoning but often lack polish or have ragged surfaces that limit their use in fine jewelry. This stone occupies a sweet spot, it is a slice that has been polished to an excellent finish, preserving the central pink heart and the surrounding green halo while offering a transparent body that plays with light. The 3.08 mm thickness makes it manageable for bezel settings, channel inlays, or custom pendants where the slice can be protected yet displayed face forward. The included clarity characteristics should be embraced as part of the gem story, they add texture and individuality, and they will be less of a concern in wearable designs that protect the stone with a secure mounting.

Value and rarity are central to the appeal of this Mozambique watermelon tourmaline, and The Natural Gemstone Company offers this stone as part of a curated selection that emphasizes provenance, natural state, and artisan finish. Mozambique has become known for producing tourmalines with pleasing hues and good transparency, and this piece reflects that regional quality while remaining unenhanced and responsibly sourced. Compared to synthetic alternatives or heavily treated stones, this natural slice provides a one of a kind aesthetic and a stable investment in color and character. For discerning buyers seeking a unique center stone or a conversation piece for a bespoke design, this watermelon tourmaline offers a compelling mix of size, 1.69 carat, precise dimensions, 8.09 by 7.88 by 3.08 mm, excellent polish, and the unmistakable natural pattern that cannot be duplicated by lab processes. If you value authenticity, tasteful color intensity, and the provenance that comes from a reputable source, this offering from The Natural Gemstone Company is a superior choice that will stand out in any collection or custom jewelry commission.
