A true collector’s highlight: we are offering rare, octahedral senarmontite crystals as a small, very well-formed cluster in an attractive size – a piece with special appeal and historical background.
Senarmontite is a rare antimony oxide mineral (Sb2O3), distinguished by its characteristic octahedral to pyramidal crystal forms.
The crystals often show glassy transparency to translucency and high luster – found in this form and as a cluster only occasionally. Chemical Formula: Sb2O3 Hardness: approx. 2–2.5 on Mohs scale (soft, handle with care!) Color: colorless, white, gray to yellowish Luster: adamantine to vitreous Crystal System: cubic (octahedral crystal form)
Special Feature: excellent crystal development, pyramidal accentuation This specimen stands out for its clear, well-defined crystal structure and harmonious arrangement in the cluster – ideal for collectors who appreciate rare oxide minerals and antimony specialties.
