This individually documented natural green Aventurine is presented by Natural Gems Belgium with its specimen-specific identification, measurements and recorded gemmological characteristics. Weighing 0.45 carats, this gemstone displays an attractive green colour with a translucent appearance and the characteristic optical phenomenon known as aventurescence.
The stone has been fashioned into a round shape with a rose cut, combining different facet arrangements to enhance its surface reflections and overall visual presentation. Measuring approximately 5.0 × 5.0 × 2.9 mm, it is a compact gemstone with a balanced outline and distinctive natural character.
Aventurine is a variety of quartz characterised by minute reflective mineral inclusions that can produce its characteristic aventurescence. Under suitable lighting, these inclusions create subtle sparkling or shimmering reflections within the stone, giving natural Aventurine its recognisable optical appearance.
This specimen is translucent, allowing a limited amount of light to penetrate the material while retaining its concentrated green body colour. Its vitreous lustre contributes to bright surface reflections, while the aventurescent inclusions provide additional visual texture and depth.
No indications of heating or other treatments have been recorded for this gemstone. It is therefore presented with its naturally occurring colour and internal characteristics as documented for the specimen.
From a gemmological perspective, Aventurine falls within the quartz family and typically shows a refractive index of approximately 1.544–1.553, with birefringence around 0.007–0.010. Its recorded specific gravity range of 2.64–2.69 and hardness of approximately 6.5–7 on the Mohs scale are also consistent with quartz-based gemstone material. Unlike strongly dispersive gemstones, Aventurine does not display significant spectral dispersion; its visual appeal is instead strongly associated with colour, translucency and aventurescence.
As a natural gemstone, internal mineral inclusions, colour variations, growth features and minor surface characteristics may occur. In Aventurine, these internal inclusions are particularly important because they contribute directly to the stone’s characteristic shimmering optical effect.
Every gemstone presented by Natural Gems Belgium is individually documented according to its recorded identification, measurements and specimen-specific characteristics. Natural inclusions, colour variations and surface features may occur and form part of the individual character of natural gemstone material.
With its appealing green colour, translucent body and characteristic aventurescence, this natural Aventurine offers an attractive combination of mineralogical interest and distinctive optical character in a compact round-cut gemstone.
