Perusing etsy a while back I stumbled on tons of jewelry where you can have a name or word written on grains of rice. It made me think of and want to break out my own tiny glass menagerie. They say artisans were so good in Turkey and India that not only would they write words on rice but create entire miniature paintings as the ultimate keepsake. The oil they're preserved in acts as a magnifying glass. Search rice jewelry on etsy and lots of these will pop up.
