This natural 𝐏𝐫𝐞𝐡𝐧𝐢𝐭𝐞 weighs 𝟏𝟏.𝟑𝟖 𝐜𝐭 and is fashioned in a distinctive 𝐨𝐜𝐭𝐚𝐠𝐨𝐧𝐚𝐥 𝐦𝐢𝐱𝐞𝐝 𝐜𝐮𝐭. The gemstone combines a soft yellowish-green body colour with prominent dark Epidote inclusions, creating a highly individual internal pattern and strong collector character.
Measuring approximately 𝟏𝟔.𝟎 × 𝟏𝟑.𝟖 × 𝟔.𝟔 𝐦𝐦, the stone presents a broad geometric face-up appearance. The clipped corners and rectangular-octagonal outline frame the inclusion pattern effectively and give the specimen a structured presentation while preserving substantial visual size.
The Prehnite displays a gentle 𝐲𝐞𝐥𝐥𝐨𝐰𝐢𝐬𝐡-𝐠𝐫𝐞𝐞𝐧 colour with subtle variations in saturation and translucency throughout the material. Its 𝐭𝐫𝐚𝐧𝐬𝐥𝐮𝐜𝐞𝐧𝐭 character allows the internal features to remain clearly observable while maintaining the soft, characteristic appearance associated with Prehnite.
A defining feature of this gemstone is its pronounced 𝐄𝐩𝐢𝐝𝐨𝐭𝐞 𝐢𝐧𝐜𝐥𝐮𝐬𝐢𝐨𝐧 𝐩𝐚𝐭𝐭𝐞𝐫𝐧. Numerous dark green to nearly black inclusions occur as fine needles, elongated blades and thicker irregular forms distributed through different levels of the gemstone. Their variable orientation produces a visually three-dimensional pattern within the lighter Prehnite host.
Several longer inclusions cross the face of the stone, accompanied by finer needle-like structures and localized concentrations. Additional cloudy internal areas and subtle structural variations are visible between the darker inclusions, reinforcing the natural character of the specimen.
The gemstone displays a clarity profile comparable to 𝐈𝟑. In this specimen, the clarity assessment primarily reflects the abundance and prominence of the natural Epidote inclusions and associated internal features. Rather than being visually concealed, these inclusions form an essential part of the stone’s collector appeal.
Prehnite is a calcium aluminium silicate hydroxide mineral that commonly occurs in pale green to yellowish-green material. Facetable transparent to translucent Prehnite is less commonly encountered than massive material, and larger faceted examples displaying clearly visible mineral inclusions can be particularly attractive as collector gemstones.
The 𝐦𝐢𝐱𝐞𝐝 𝐜𝐮𝐭 is assessed as 𝐠𝐨𝐨𝐝, with 𝐠𝐨𝐨𝐝 𝐬𝐲𝐦𝐦𝐞𝐭𝐫𝐲 and 𝐠𝐨𝐨𝐝 𝐩𝐨𝐥𝐢𝐬𝐡. The broad facets provide surface reflection while leaving the internal Epidote structures clearly visible, creating an effective balance between faceted presentation and inclusion display.
The gemstone also shows a 𝐠𝐨𝐨𝐝 𝐯𝐢𝐭𝐫𝐞𝐨𝐮𝐬 𝐭𝐨 𝐩𝐞𝐚𝐫𝐥𝐲 𝐥𝐮𝐬𝐭𝐞𝐫, adding brightness to the softly translucent yellowish-green material.
A 𝐬𝐦𝐚𝐥𝐥 𝐜𝐡𝐢𝐩 is present and is primarily visible under magnification. It is documented as part of the gemstone’s current condition and has limited visual impact during normal face-up observation.
There are 𝐧𝐨 𝐢𝐧𝐝𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐡𝐞𝐚𝐭𝐢𝐧𝐠 and 𝐧𝐨 𝐢𝐧𝐝𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐚𝐧𝐲 𝐨𝐭𝐡𝐞𝐫 𝐭𝐫𝐞𝐚𝐭𝐦𝐞𝐧𝐭 for this gemstone.
This specimen is Evaluated 𝐛𝐲 𝐍𝐚𝐭𝐮𝐫𝐚𝐥 𝐆𝐞𝐦𝐬 𝐁𝐞𝐥𝐠𝐢𝐮𝐦, with its individual characteristics and treatment status documented for identification and verification.
With its geometric octagonal form, soft yellowish-green colour and dramatic network of natural Epidote inclusions, this 11.38 ct Prehnite offers a highly distinctive combination of faceted craftsmanship and visible mineralogical character. Its inclusion-rich interior makes each viewing angle different and gives the gemstone particular appeal as an individual collector specimen.
