Garnet – The Fire of the Earth
Garnet is one of the most diverse gemstone groups and has captivated people for millennia with its intense luminosity. Its characteristic red coloration is created by iron and manganese compounds – but garnets come in almost all colors, from vibrant orange to rare green

Cut & Shape

Inclusions & Characteristics
Garnets are natural stones – inclusions are a sign of authenticity and not a flaw. Only under a microscope does the true nature of the stone reveal itself.
Typical inclusions:
- Needle-like crystals (create the coveted asterism/star effect in cabochons)
- Fingerprint inclusions (healed fractures)
- Crystal inclusions (mineral crystals inside)
- Feather inclusions (partial fractures)
- Zoning (color bands or zones)
Quality grades: Eye-clean (no inclusions visible to the naked eye) is considered premium quality. Slight inclusions are normal in natural stones and only slightly reduce their value. Strong inclusions can impair transparency and brilliance.
Special feature: Demantoid garnets often exhibit characteristic "horsetail" inclusions of byssolite fibers – a unique quality feature and proof of authenticity, not a defect.
Treatment & Authenticity
Natural garnets are typically untreated – which makes them particularly valuable and authentic. Transparency in declaration is a matter of course for us.
Thermal Treatment (Heating): Rarely applied to some garnet varieties – garnets usually retain their color naturally and do not require treatment.
Filling with Glass/Resin: For heavily fractured stones – significantly reduces value, not in our assortment.
Untreated (Natural): The norm for garnets – especially for Demantoid, Tsavorite, and Rhodolite. Natural color without any interventions.
Certificates of Authenticity: All our garnets are natural stones. Upon request, we provide certificates from renowned laboratories (GIC, GRS, Gübelin, SSEF). We do not carry synthetic or simulated stones.
