Indonesian petrified palm root oval cabochon, 51–57 × 22–24 mm. Mirror polish on convex face, flat back. The pattern of silicified vascular cells —palm tissue converted into mineral— makes each of these pieces unique.

This specific piece
The elongated oval format (~51–57 × 22–24 mm) favors longitudinal pendants: the piece hangs centrally, and its width-to-length ratio is visually dynamic. Compared to the XL teardrop format in the catalog, this oval is more contained and fits silver settings without needing a fully custom bezel. The background color ranges from beige, toasted brown, to gray depending on the variation.
How petrified palm root is formed
Silicification occurs when plant tissue is buried in volcanic sediments rich in dissolved silica. SiO₂ replaces organic matter atom by atom without altering the cellular geometry. In Indonesia, this process occurred in Neogene basins (5–23 M.a.), preserving the vascular architecture of the original palm with microscopic detail.
What mounting it works for
-
Pendants with bezel in 925 silver or copper — the elongated oval proportion works well for vertical pendants; a simple bezel allows the pattern to take center stage.
-
Brass or bronze settings — the warm tones of brass complement the beige and brown of the fossil.
-
Wire wrap — flat back facilitates anchoring; the oval shape is compatible with medium variation weaves.
Petrified palm root in the lapidary market
It is mainly extracted in Java and Kalimantan, where Neogene volcanic sedimentary deposits have preserved plant structures for millions of years. In the international lapidary market, it is known as "palm root fossil" or "petrified palm root," prized for the regularity and size of its cellular pattern. In crystal traditions, it is associated with grounding, patience, and connection to deep time.
The symbolic properties attributed to minerals belong to cultural and historical traditions. They are shared for educational purposes, not as medical advice.
How to recognize genuine petrified palm root
The pattern should be three-dimensional under magnification: cells with real depth, not a surface print. Hardness ~6.5–7 Mohs; not scratched by a steel knife. Resin imitations are notably lighter than silica.
Frequently Asked Questions
Is the pattern natural or printed?
Natural. Cellular microstructure of palm preserved in silica for millions of years. No detectable treatment; statement based on lapidary observation.
What setting is it designed for?
We recommend a closed bezel in 925 silver, copper, or brass. The oval proportion is compatible with standard bezel templates for pendants.
How do I know which variation is mine?
Each variation has its exact dimensions in the name. The piece you receive corresponds to the selected variation number.
Are the measurements exact?
Tolerance ±0.5 mm, as these are individual freeform pieces.
Is it the same material as the teardrop format?
Yes, same mineral and origin. The difference is the shape: this listing offers an elongated oval (51–57 × 22–24 mm); the other offers XL teardrop sizes (46–68 mm).
How do I care for it?
Warm water and neutral soap, dry with a soft cloth. Avoid ultrasonics. More at jewelry care.
