This Specific Piece
The copper structure combines a large open circle with three concentric spiraling inner rings and a small sphere in the center, flanked by two geometric triangles on the sides. The result is a composition that fills the entire space of the pendant and projects a characteristic openwork shadow onto the skin.
The oval moonstone exhibits high-intensity rainbow adularescence: when the piece is moved under natural light, blue, green, and orange flashes are simultaneously perceived. The tear-drop amethyst closes the piece at the bottom with a medium violet and homogeneous translucency.
Copper Electroforming
This piece is made using electroforming: copper is electrolytically deposited onto a mold until a solid structure with controlled thickness is built. The technique allows for the creation of openwork shapes—like the arches and triangles of this pendant—with thin but resistant walls, retaining the characteristic granular texture of the process.
Moonstone in Lapidary Tradition
Moonstone has been used in jewelry since classical antiquity; Rome and Greece valued it for its pearly luster, which they attributed to moonlight trapped in the stone. The optical phenomenon responsible—adularescence—is produced by the dispersion of light between layers of feldspar of different composition.
In crystal tradition, moonstone is associated with intuition and natural cycles. Amethyst, for its part, is historically linked to serenity and clear thinking—its name derives from the Greek amethystos, "not intoxicated."
The symbolic properties attributed to minerals belong to cultural and historical traditions. They are shared for educational purposes, not as medical advice.
Care of Electroformed Copper
Copper can develop a green patina (verdigris) in areas of skin contact or in humid environments. Store in a zip bag, remove before showering, and clean with a dry cloth. See jewelry care guide.
Frequently Asked Questions
What is moonstone adularescence?
Adularescence is the optical phenomenon that produces the floating, multi-colored glow of moonstone. It is caused by the interference of light between alternating layers of feldspar of different composition (albite and orthoclase). It is not a coating or treatment: it is a structural property of the mineral.
Is the pendant too large for daily wear?
At 74 × 45 mm, it is a statement piece designed to be worn as a central element. The weight is less than what the size suggests due to the openwork copper structure, which leaves much of the space open.
How do you care for moonstone?
Clean with a dry or slightly damp cloth. Avoid ultrasonics and acids. Moonstone has cleavage in two directions and is sensitive to impacts. See the jewelry care guide.
