a like or two

Small objects encased in glass for the purpose of knick-knack or decoration.  Especially: insects, whimsical nature figures, shiny bits.  

When I am bored and under the influence I like to research precious and semiprecious gemstones, and minerals.  Especially: Opal, ammolite, famous diamonds, silly "crystal powers"; etc. 

If you are likewise interested you may find The Smithsonian Gem & Mineral Collection quite titillating.  

A collection of over 1,000 "Picture Agates."  Those little pictures formed naturally in the rock.  They look like silky jelly candies and I want to eat them.
