At Minéraux d’Ailleurs, we offer professionals carefully selected Onyx. However, the mineral market contains many imitations. Knowing how to distinguish genuine Onyx from an artificial or dyed stone is essential to guarantee the authenticity of your products.
The characteristics of genuine Onyx
Onyx is a variety of agate belonging to the chalcedony family. It is distinguished by:
Its color: deep black or black marbled with white/beige bands.
Its texture: smooth and uniform surface, with a hardness of 7 on the Mohs scale.
Its density: heavier than glass or synthetic stones.
Its natural bands: sometimes irregular patterns, never perfectly uniform.
Common imitations of Onyx
The market sometimes offers alternatives sold as Onyx that are not:
Dyed glass: often lighter, shinier, and without natural bands.
Dyed chalcedony: a natural stone artificially colored to imitate black Onyx.
Plastic or resin: extremely light and not very resistant to scratches.
Observation of the bands: color variations are irregular and natural, unlike uniform dyes.
Weight: Onyx is dense and feels heavy in the hand.
Temperature: a natural stone remains cool to the touch, unlike plastic or heated glass.
Precautions for professionals
As retailers, jewelers, or therapists, it is recommended to work with trusted suppliers to avoid counterfeits. At Minéraux d’Ailleurs, we guarantee natural Onyx from responsible and traceable supply chains.
Why choose genuine Onyx?
Beyond aesthetics, authentic Onyx retains its lithotherapeutic properties: grounding, protection, and strengthening self-confidence. An imitation, even visually similar, cannot reproduce these energies.
Conclusion
Knowing how to recognize genuine Onyx is essential to guarantee your customers the quality and authenticity of their minerals. A watchful eye, a few simple tests, and a reliable supply are the keys to a successful selection.
