Natural Tourmaline · 3.429 ct · Cushion · Green · Unheated

This natural Green Tourmaline weighs 3.429 carats and is fashioned in an elegant cushion-shaped mixed cut, combining substantial size with exceptional internal cleanliness and a rich deep olive-green colour.

Measuring approximately 10.1 × 9.7 × 4.9 mm, the gemstone presents a broad face-up appearance with balanced proportions. Its cushion outline gives the stone a refined yet substantial presence, making it particularly suitable as a centre stone for a custom jewellery design.

The gemstone displays a distinctive olive-green body colour, accompanied by lively yellowish-green reflections under direct illumination. These tonal variations add depth to the colour while remaining consistent with the natural pleochroic character of Tourmaline.

Green Tourmaline is traditionally referred to in the gemstone trade as Verdelite, a colour-variety designation used for green members of the Tourmaline group. The exact mineral species within the group should only be assigned when specifically established by mineralogical testing.

A major quality characteristic of this specimen is its exceptional clarity. The gemstone is transparent and presents a clarity comparable to approximately VVS to IF, with only minute natural internal characteristics expected to be visible under magnification. This high degree of internal cleanliness allows excellent light transmission and gives the gemstone an unusually clear and open appearance for Tourmaline.

The cushion mixed cut is assessed as Good, while Good to Very Good symmetry supports a balanced outline and orderly facet arrangement. Good to Very Good polish produces clean reflective surfaces and an attractive vitreous luster.

The deep olive-green body colour remains sufficiently open to transmit light effectively, while the transparent interior and high clarity allow yellowish-green reflections to become visible across the faceted surface under stronger illumination.

At 3.429 ct, the gemstone combines considerable size with unusually high transparency and internal cleanliness, giving it strong visual presence without sacrificing refinement.

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 substantial 3.429 ct weight, deep olive-green colour and exceptionally clean VVS to IF clarity profile, this natural Green Tourmaline combines size, transparency and refinement in a particularly attractive specimen. Its cushion cut, lively yellowish-green reflections and untreated condition make it highly suitable for fine custom jewellery or a carefully selected gemstone collection.
