Authenticity & care

Authenticity

Every MINERALIA piece is a natural stone. Each listing describes the individual specimen, and we disclose any known treatment such as heating or dyeing.

Caring for your stones

• Keep stones away from prolonged direct sunlight; some colours, amethyst for example, can fade.
• Avoid harsh chemicals, ultrasonic cleaners and sudden heat.
• Clean with a soft, dry cloth. Softer stones (Mohs hardness below 5) should never be soaked.
• Store pieces separately so harder stones do not scratch softer ones.
