Natural Prehnite with Epidote Inclusions · 26.86 ct · Pear · Yellowish Green · Unheated

This natural 𝐏𝐫𝐞𝐡𝐧𝐢𝐭𝐞 weighs an impressive 𝟐𝟔.𝟖𝟔 𝐜𝐭 and is fashioned in a large 𝐩𝐞𝐚𝐫-𝐬𝐡𝐚𝐩𝐞𝐝 𝐦𝐢𝐱𝐞𝐝 𝐜𝐮𝐭. The gemstone displays a soft yellowish-green body colour combined with highly distinctive dark Epidote inclusions that create a striking natural internal landscape.

Measuring approximately 𝟐𝟔.𝟎 × 𝟏𝟗.𝟑 × 𝟗.𝟕 𝐦𝐦, this is a substantial faceted specimen with excellent visual presence. Its large face-up dimensions allow the internal structure to be observed clearly and make the inclusion pattern an important part of the gemstone’s overall character.

The body colour ranges through gentle 𝐲𝐞𝐥𝐥𝐨𝐰𝐢𝐬𝐡-𝐠𝐫𝐞𝐞𝐧 tones, with subtle variation in saturation across the stone. The material is 𝐭𝐫𝐚𝐧𝐬𝐥𝐮𝐜𝐞𝐧𝐭, allowing light to penetrate the gemstone while simultaneously revealing the abundant internal inclusions.

One of the most distinctive characteristics of this specimen is its pronounced 𝐄𝐩𝐢𝐝𝐨𝐭𝐞 𝐧𝐞𝐞𝐝𝐥𝐞 𝐚𝐧𝐝 𝐞𝐥𝐨𝐧𝐠𝐚𝐭𝐞𝐝 𝐢𝐧𝐜𝐥𝐮𝐬𝐢𝐨𝐧 𝐩𝐚𝐭𝐭𝐞𝐫𝐧. Dark green to nearly black inclusions occur as fine needles, elongated blades and locally denser aggregates throughout the gemstone. Their irregular orientation and distribution create a dramatic contrast against the lighter Prehnite host material.

The gemstone displays a clarity profile comparable to 𝐈𝟑. In this case, the lower clarity designation is primarily the result of the abundant and clearly visible natural inclusions rather than an absence of visual interest. These inclusions are a defining characteristic of the specimen and give the stone a highly individual collector-oriented appearance.

Prehnite is a calcium aluminium silicate hydroxide mineral and commonly occurs in pale green, yellowish-green and occasionally nearly colourless material. Transparent to translucent facetable material is less common than massive or cabochon-grade Prehnite, particularly in larger sizes such as this specimen.

The 𝐦𝐢𝐱𝐞𝐝 𝐜𝐮𝐭 combines different facet arrangements to preserve the substantial size of the material while producing surface reflection and highlighting the internal inclusion pattern. The cut, polish, symmetry and luster are all assessed as 𝐠𝐨𝐨𝐝, resulting in an attractive overall presentation despite the strongly included nature of the stone.

The gemstone shows a pleasant 𝐯𝐢𝐭𝐫𝐞𝐨𝐮𝐬 𝐭𝐨 𝐩𝐞𝐚𝐫𝐥𝐲 𝐥𝐮𝐬𝐭𝐞𝐫, with reflective facets adding brightness to the otherwise softly translucent body.

There are 𝐧𝐨 𝐢𝐧𝐝𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐡𝐞𝐚𝐭𝐢𝐧𝐠 and 𝐧𝐨 𝐢𝐧𝐝𝐢𝐜𝐚𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐚𝐧𝐲 𝐨𝐭𝐡𝐞𝐫 𝐭𝐫𝐞𝐚𝐭𝐦𝐞𝐧𝐭, preserving the natural condition and internal features of the specimen.

This gemstone is Evaluated 𝐛𝐲 𝐍𝐚𝐭𝐮𝐫𝐚𝐥 𝐆𝐞𝐦𝐬 𝐁𝐞𝐥𝐠𝐢𝐮𝐦, with its individual characteristics and treatment status documented for identification and verification.

With its impressive 26.86 ct weight, substantial pear-shaped presentation and dramatic natural Epidote inclusions, this Prehnite is particularly distinctive as a collector gemstone. Rather than hiding its internal features, the large faceted form reveals them prominently, creating a unique contrast between the soft yellowish-green Prehnite and the dark elongated inclusions.
