A type of stony-iron meterorite called "pallasite". The green parts are olivine. This is believed to be a material that can be found in large quantities at the core mantle boundary of larger rocky planets.

Two end members:

• iron-olivine: Fe₂SiO₄
• magnesium-olivine: Mg₂SiO₄

Other properties:

• Mohs 6.5 to 7.0
• Orthorhombic – (Nesosilicate like topaz)
• (Nontrivial base cell?)

Suitability as a base material for gemstone metamaterial technology seems quite good.

Some Trivia

Olivine is an extremely common mineral.
It is believed that there are large quantities of this stuff down at the core mantle boundary of Earth and above.
We know that from stony–iron meteorites called "pallasites" (very pretty to look at).
The asteroid psyche is believed to be the biggest arteroid in the asteroid belt that is mainly made out of pallasite.

Artificially mechanosynthesized ultra pure and flawless olivine would likely be colorless not green.
