Olivine in Basalt Matrix is a natural volcanic rock specimen featuring green olivine crystals embedded within a dark basalt host rock. Formed during the cooling of basaltic lava, specimens from the USA are prized for their striking contrast between the vibrant green olivine and fine-grained black basalt.
Olivine has a hardness of 6.5–7 on the Mohs scale, while the surrounding basalt provides a durable natural matrix. These specimens are popular among mineral collectors, educators, and geology enthusiasts for their unique volcanic origin.
Each specimen displays distinctive crystal sizes, natural textures, and color variations, making every piece one of a kind.
