Natural Tourmaline · 4.14 ct · Oval · Deep Olive Green · Unheated

This impressive natural Green Tourmaline weighs 4.14 carats and combines substantial size with a rich deep olive-green colour, good transparency and an attractive faceted oval presentation.

Measuring approximately 10.0 × 9.2 × 6.7 mm, the gemstone has considerable visual presence while maintaining balanced proportions. Its generous carat weight allows the depth and tonal complexity of the green colour to be appreciated particularly well.

The body colour is a distinctive deep olive green, combining darker green tones with subtle yellowish or olive nuances. Tourmaline is naturally pleochroic, meaning that variations in colour intensity and tone may become visible when the gemstone is observed from different crystallographic directions or under changing illumination.

The gemstone is transparent and presents a clarity comparable to approximately VS. In a Tourmaline of this size and depth of colour, the combination of transparency and comparatively moderate inclusion content contributes significantly to its overall visual quality.

Cut quality is assessed as Good, providing an effective presentation of the gemstone’s deep green colour. Fair to Good symmetry reflects some variation in facet alignment and outline, while Good to Very Good polish produces clean reflective surfaces and an attractive vitreous luster.

The relatively deep body colour remains clear rather than excessively closed, allowing light to travel through the transparent material and producing lively green reflections across the faceted surface.

At 4.14 ct, the gemstone also offers substantial size for a natural Green Tourmaline, making it particularly suitable as a centre stone for a custom jewellery design or as an individual collector gemstone.

The stone is recorded as unheated, preserving its naturally observed colour without documented heat enhancement.

With its substantial 4.14 ct weight, transparent body and distinctive deep olive-green colour, this natural Green Tourmaline offers strong visual presence and considerable individual character. Its combination of size, colour depth, good transparency and polished faceted presentation makes it an attractive choice for fine custom jewellery or a carefully selected gemstone collection.
