Kambaba Jasper Rings in Sterling Silver  

About Kambaba Jasper: Earth's Oldest Fossilized Stone

Kambaba jasper rates 6.5 to 7 on the Mohs hardness scale, making it durable enough for everyday ring wear. The stone belongs to the rhyolite family rather than true jasper, though jewelers have used the jasper name for decades. Its green-black coloring comes from embedded microcrystalline quartz and the remains of prehistoric algae structures called stromatolites. The circular patterns you see in kambaba jasper are cross-sections of ancient bacterial mats that built up layer by layer in shallow primordial seas. No two stones share the same pattern distribution, so each ring carries a distinct arrangement of these fossil formations. The material takes a strong polish and holds up well against scratches. We source our kambaba jasper from verified suppliers who work with material from Madagascar's deposits. Every ring in this collection uses solid .925 sterling silver settings. SilverRush Style has specialized in natural stone jewelry since 2005. Check back soon as we update our kambaba jasper ring inventory regularly.
