Epidote Included Quartz Cabochon

Elongated oval cabochon of clear quartz with green epidote inclusions, 24 × 11 × 4 mm. The epidote formations create dendritic structures visible to the naked eye: small prismatic crystals floating in the vitreous quartz matrix. Hand-cut in our lapidary workshop.

Item details

This specific piece

The epidote inclusions form a dendritic cluster in bottle green tones with ochre flashes at the edges of each crystal. The quartz matrix is semi-transparent: it softly filters light and allows the formations to be seen in depth, creating a window-like effect into the stone's interior. The visual texture varies with the lighting angle, revealing different planes of inclusion.

The lapidary decision was to maintain the elongated proportion —24 mm on the long axis, 11 mm wide— to expose the greatest length of the growth axis of the epidote needles. A wider cabochon would have cut the formations crosswise and lost the linear effect that defines this piece.

How epidote inclusions form in quartz

Epidote forms under low to medium-grade metamorphic conditions, often in rocks altered by hydrothermal fluids rich in calcium and iron. When quartz is subsequently deposited —from hot fluids that saturate rock fissures— it encapsulates pre-existing epidote crystals. The result is a mineral inclusion within a vitreous matrix: the epidote remains trapped in its original position.

What mounting it works for

• Bezel setting (925 silver or gold) — The elongated oval shape and slender 4 mm profile facilitate a low-wall bezel that leaves the entire inclusion area visible. Ideal for a central pendant or statement ring in 925 silver.
• Long or medium-length pendants — The 24 × 11 mm proportion works especially well when the piece hangs vertically; the long axis of the cabochon aligns with the natural direction of vision.
• Wire wrap — An alternative for those who work with wire wrapping; the slender 4 mm profile allows for a clean wrap with copper or silver in 20-22 gauge.

Epidote in lapidary tradition

Epidote has been known since antiquity under regional names such as "pistacite" (due to its pistachio-like color in some varieties).

In crystal tradition, quartz with epidote is associated with the artisan's patience and the beauty of what grows slowly. The green of its inclusions evokes presence and rootedness. A stone especially appreciated in conceptual and collector's jewelry.

How to recognize genuine quartz with epidote

Authentic epidote inclusions feature prismatic crystals with well-defined terminations: they are not diffuse spots or homogeneous colorations. Under a jeweler's loupe: the crystals have flat faces and a recognizable profile. The color is intense green to yellowish green with slight translucency in larger crystals.

Frequently asked questions

What is the origin of the material?

This cabochon comes from deposits in Brazil, an area with notable production of inclusionary quartz. The inclusions are metamorphic epidote; no treatment or enhancement has been applied to the material.

What type of setting do you recommend?

We recommend a closed bezel setting in 925 silver. Quartz has a hardness of 7 Mohs, sufficient for daily wear, but the bezel protects the cut edges. With a 4 mm profile, it is compatible with standard wall bezels for artisan jewelry.

Does it have any applied treatment?

No detectable treatment. No dyeing, stabilization, or heating. The green color of the inclusions is natural mineral epidote. Statement based on lapidary observation; the piece does not include formal gemological certification.
