This specific piece
Ruby in fuchsite is a mineral combination where chrome-red corundum (Al₂O₃) crystals naturally coexist with a fuchsite matrix — a variety of muscovite mica that also owes its green color to chromium (Cr³⁺).
The shapes in this lot are varied — not standardized — allowing the jeweler to select the silhouette that best suits their design.
How ruby in fuchsite forms
Ruby in fuchsite forms in metamorphic contexts, typically in schists and gneisses from subduction zones or continental collision.
For which mounting it works
-
Silver 925 bezel setting — essential given the very low hardness of fuchsite (2–2.5 Mohs); the closed bezel protects the stone's edge from scratches and allows it to be safely used in a pendant or earring.
-
Pendants with silver mounting — the red-green contrast stands out as a focal point in any pendant design; the scale (18–35 mm) allows for formats from medallion to large pendant.
-
Wire wrap — an alternative for those working with wire; for a hardness of 2–2.5 Mohs, the wire wrap must cover the edges well to minimize exposure to friction; 18–20 gauge wire provides the necessary structural support.
Ruby in lapidary tradition
Ruby (red corundum) is one of the four traditional precious stones along with diamond, emerald, and sapphire. The term "ruby" derives from the Latin ruber (red). In 1st century AD India, the Sanskrit texts of the Ratnapariksha described ruby as the most valuable gem, associated with the sun and sovereign power. Rubies from the Mogok metamorphic belt (Burma) and Karnataka (India) were for centuries the most prized in the international gem trade.
In crystal tradition, ruby is associated with vitality and determination; fuchsite, with self-awareness and emotional healing.

How to recognize genuine ruby in fuchsite
Genuine ruby in fuchsite shows corundum crystals with high-intensity vitreous luster embedded in the silky matrix of green mica.
Frequently Asked Questions
Are these gem-quality rubies or just lapidary rubies?
The ruby crystals in these pieces are genuine red corundum, but of lapidary quality — opaque or semi-opaque, without the transparency needed for fine faceted jewelry.
Why is the hardness so low if ruby is 9 Mohs?
Fuchsite (mica) is only 2–2.5 Mohs and is the matrix that occupies most of the piece's surface.
Which variant do I receive? Can I choose?
Yes. The variants are numbered (24–27) with the exact dimensions in the title.
Is it treated?
Untreated. The red color of the ruby and the green of the fuchsite are natural and produced by chromium in both minerals.
What are the dimensions with tolerance?
The exact dimensions of each variant are in the title: variant 24 (35×22×6 mm), variant 25 (33×28.7×7.5 mm), variant 26 (20.4×17×6 mm), variant 27 (18×17×5.4 mm).
How to care for it?
Clean with a soft cloth and cold water without soap (fuchsite is sensitive to abrasion). Avoid ultrasonics, which can separate the mica layers. Store individually wrapped in a soft cloth. See complete jewelry care guide.
