This individually documented natural Tourmaline is presented by Natural Gems Belgium with its specimen-specific identification, measurements and recorded characteristics. Weighing 0.88 carats, this transparent gemstone displays an attractive intense purplish-pink colour, combining vivid pink tones with a distinct violet influence.

The gemstone has been fashioned into a classic round shape with a brilliant cut, designed to maximise light return and enhance the visual intensity of the stone. Measuring approximately 5.48 × 5.61 × 4.34 mm, it offers well-proportioned dimensions and a compact size suitable for a wide range of jewellery applications.

Its transparent character allows light to pass effectively through the gemstone, helping to emphasise both brilliance and colour saturation. The intense purplish-pink appearance gives this Tourmaline a distinctive and lively visual character, particularly under bright or directional lighting.

This gemstone has been recorded as irradiated. Irradiation is a treatment used in certain gemstones to modify or enhance colour by exposing the material to controlled radiation. The treatment is disclosed as part of the documented characteristics of this individual specimen.

Tourmaline is a complex borosilicate mineral group known for its exceptionally broad range of natural colours. Pink Tourmaline is especially valued for shades ranging from delicate pastel pink to strongly saturated purplish and reddish pink tones. Variations in chemical composition during crystal growth are responsible for much of this colour diversity.

As a natural gemstone, this Tourmaline may contain small inclusions, subtle colour zoning or minor surface-reaching features. These characteristics can occur naturally during crystal formation and are part of the individual identity of natural gemstone material.

Every gemstone presented by Natural Gems Belgium is individually documented according to its recorded identification and specimen-specific characteristics. Natural inclusions, colour zoning and surface features may occur and contribute to the unique appearance of each natural stone.

With its vivid intense purplish-pink colour, transparent appearance and classic round brilliant cutting, this 0.88 ct natural Tourmaline offers a striking combination of colour and brilliance for gemstone collectors or distinctive jewellery designs.
