Jar of Mexican Opals

One Jar of rough Mexican Cantera opals from the Magdelena mine. Cantera is the Mexican name of the host rock, rhyolite. 
This jar contains lots of bright opals with rhyolite host rock.  
This jar measures 5" tall and 1 1/2" in diameter. 
I bought these originally with the intention of learning lapidary work. No time for that. What was I thinking? 
A great idea though would be to place them in a decorative bottle with water and use them as a decoration like this:
This jar marked #4.
