Natural Tourmaline · 1.82 ct · Round · Brilliant Cut · Unheated

This natural Green Tourmaline weighs 1.82 carats and is fashioned in a classic round brilliant cut, combining a balanced circular outline with a facet arrangement designed to enhance brightness, transparency and the gemstone’s distinctive yellowish olive-green colour.

Measuring approximately 7.3 × 7.3 × 5.0 mm, the gemstone presents a substantial face-up diameter and useful depth, giving it a strong visual presence suitable for individual jewellery design.

The stone displays an attractive yellowish olive-green body colour, offering a warmer and more earthy expression of green than the vivid chromium-rich greens seen in Chrome Tourmaline. Depending on lighting and viewing orientation, subtle variations between yellowish-green and olive-green tones may become visible.

Green Tourmaline is often referred to in the gemstone trade as Verdelite, a traditional colour-variety name used for green members of the Tourmaline group. The exact mineral species within the Tourmaline group can vary and should not be assigned without specific mineralogical identification.

The gemstone is transparent and presents a clarity comparable to approximately SI1, with natural inclusions, internal growth features and minor healed fissures visible under magnification. These characteristics have a moderate influence on internal cleanliness but do not prevent the gemstone from retaining good transparency and an attractive face-up appearance.

Tourmaline is valued for its broad natural colour range and pronounced pleochroism. In green material, directional colour differences may range from lighter yellowish-green to deeper or more olive-toned green depending on crystal orientation and viewing direction.

The round brilliant cut is assessed as Good, providing an effective overall presentation of the colour and transparent material. Fair to Good symmetry introduces some variation in facet alignment, while Fair to Good polish supports a pleasing vitreous surface luster.

There are no indications of heating and no indications of any other treatment. The gemstone is therefore presented with its naturally observed colour and internal characteristics without documented enhancement.

With its warm yellowish olive-green colour, transparent body and classic round brilliant presentation, this 1.82 ct natural Green Tourmaline offers distinctive natural character and versatile jewellery potential. Its untreated condition and subtle pleochroic colour variation make it an attractive choice for custom jewellery or a carefully selected gemstone collection.
