What is an emerald?

Emerald is green beryl, its color created by chromium and vanadium impurities. It is the most coveted green gemstone in the world – but is almost always delivered with natural inclusions (the so-called "jardin"), which is not a flaw, but rather a sign of authenticity.

What is the Jardin?

Natural inclusions and fine cracks in emeralds are called jardin (French for garden). A completely clear emerald would be suspicious – inclusions prove its natural origin.

Emerald Care

• Almost all emeralds are oiled (cedarwood oil) – accepted and standard
• No ultrasound, no steam cleaner – dissolves the oil
• Only lukewarm soapy water for cleaning

Best Origin

• Colombia (Muzo, Chivor): World's best quality
• Zambia: Slightly darker blue-green – also high quality
