There are stones that need no introduction: their story is written in color. Chrysocolla carries in its veins the trace of the copper that formed it—those blues and greens that change with the light are the same copper that tints turquoise and ancient enamels, mineralized here alongside silica for thousands of years. This pendant is a conversation between that stone and silver: a 28 × 22 × 6 mm piece, a freeform cabochon set in 925 sterling silver. A 45 cm silver chain is included. Unique piece.
The stone: chrysocolla
Chrysocolla is a hydrated copper and aluminum silicate (approximate formula (Cu,Al)₂H₂Si₂O₅(OH)₄·nH₂O) that forms as a secondary mineral in the oxidation zones of copper deposits—where infiltrating water dissolves native copper and recombines it with silica. Its color, from light turquoise to deep green, comes from the presence of copper in its structure; brown or dark veins are residues of iron and manganese oxides from the host rock. The main deposits are in Peru, Chile, Arizona (USA), and the Democratic Republic of Congo; in antiquity, it was already worked in Egypt and the Eastern Mediterranean as a pigment and makeup.
The hardness of chrysocolla depends on its degree of silicification. Pure chrysocolla (2.5–3.5 Mohs) is too soft for jewelry; the material suitable for cabochons is chrysocolla with intergrown silica—microcrystalline quartz or chalcedony—which reaches 6–7 Mohs and allows for carving and polishing. This piece is of that type. Chrysocolla is opaque: the blue-green color is appreciated by reflection on the polished surface.
The SOFIA design
The name SOFIA comes from the Greek σοφία — "wisdom." The choice is not arbitrary: chrysocolla is a stone that accumulates time. The copper atoms that give it color took thousands of years to reorganize into that mineral; the artisan took hours to hand-carve the cabochon and conform the bezel to its exact perimeter. That is what SOFIA names—not the color or the stone, but the process behind the piece.

Manufacturing technique
The piece is entirely produced in our workshop. The cabochon is hand-carved in a freeform shape: an irregular, non-standard silhouette chosen to frame the area of the stone with the best color and vein distribution. The back is polished flat so that it sits cleanly on the silver base.
The setting is built around the cabochon: the silver strip is shaped to its exact perimeter, and the bezel is closed by hand once the stone is in place. Finally, the oxidized finish is applied through controlled sulfuration, which darkens the silver, giving it an aged tone.
Chrysocolla in history
Chrysocolla was described by Theophrastus in the 4th century BC with the name chrysokolla ("gold" + "glue"), due to its use as a flux in gold soldering. As a blue-green pigment, it is documented in Egypt since the second millennium BC. In pre-Columbian metallurgy in Peru and Bolivia, it was carved as a gem from at least the Mochica culture, which recognized the symbol of water in its color. The mineral now set in 925 silver has a history of human work spanning millennia.
In crystal traditions, chrysocolla is associated with serene communication and the wisdom of measured words. It is considered the stone of those who speak from calmness—of the orator, the mediator, one who chooses well what to say and when to say it.

Pendant care
This piece has character and deserves it: the oxidized finish is a deliberately applied patina, not an imperfection. To ensure it continues to tell its story over time, avoid using aggressive polishing paste or anti-tarnish cloths on the darkened areas—these would remove the desired effect and expose the bright silver underneath. To clean, simply use warm water with mild soap and a soft cloth; if the patina lightens with continuous use, it is a normal part of the piece's aging. Silicified chrysocolla (6–7 Mohs) withstands daily use, but like any copper mineral, it is advisable to remove the pendant before showering, exercising, sleeping, or applying perfume, lotion, or sunscreen—chemical products can alter both the metal's patina and the mineral's copper content.

Frequently Asked Questions
Is chrysocolla authentic?
Yes. It is chrysocolla in silica—copper silicate intergrown with microcrystalline quartz or chalcedony, the commercial form suitable for jewelry. No detectable treatment: the blue-green color comes from the copper naturally present in the mineral structure, and the veins are remnants of the original matrix that the lapidary preserves as part of the pattern. Statement based on lapidary observation; the piece does not include formal gemological certification.
Why is the silver dark?
The oxidized finish is a deliberately applied patina: the surface of 925 silver is treated with controlled sulfuration to darken it, creating an aged tone that contrasts with the blue-green of the cabochon. It is not dirt or a defect; it is the finish of the SOFIA design. The patina may lighten with continuous use, which is part of the natural aging of the piece—if at some point the original contrast is preferred, it can be repatinated in a workshop.
What does SOFIA mean?
SOFIA comes from the Greek σοφία, "wisdom." The name originates from the history of the mineral—a stone with millennia of human work behind it—and the careful craftsmanship required for each piece: hand-carving, shaping the bezel, choosing the finish. Wisdom as a synonym for time and attention.
Can it be worn daily?
Yes, with normal silver jewelry care. Silicified chrysocolla (6–7 Mohs) withstands continuous use as a pendant without problems. It is advisable to remove it for sleeping, showering, exercising, or applying perfumes and creams: chemical products can alter the oxidized patina of the silver and, with prolonged exposure, affect the copper in the mineral.
Can the chain be changed?
Yes. The 45 cm 925 sterling silver chain is detachable and can be replaced with another chain—40 cm for a choker, 50 or 60 cm for a long pendant—depending on the preferred drop.
Is it a unique piece?
Yes. The SOFIA design is part of a recurring collection, but each pendant is assembled from a different chrysocolla cabochon: the pattern of blues and greens, the arrangement of the veins, and the exact silhouette of the cabochon are unique to this piece.
About stone selection: each chrysocolla cabochon undergoes visual verification of color, veins, and material cohesion before being set in the workshop. The material is selected for color density and a vein pattern that works well in pendant form—the size of the piece (28 × 22 mm) is generous, so the stone's pattern is legible at a close distance.
