Diamonds in the Rough

Yesterday, upon returning from their weekly walk to the library, David presented me with a paper lunch bag with the label "DIMONDS (EMRALDS)"

When opening the bag, I saw some lovely broken auto glass that had broken into gem-sized pieces. They had a slightly bluish-green cast to them, so they did indeed look a little bit like diamonds/emeralds.

I've never gotten a sack full of gems before! What a thoughtful Valentine's present.
