Vintage 1950s Mother-of-Pearl Shell Caviar Dish for Jewelry

I find vintage caviar dishes are always designed in such a way that suggests something special sits inside (for good reason, of course), which makes them ideal for housing your prettiest jewelry pieces. I scooped up one of these iridescent shells at an antiques market about five or so years ago to cradle a few favorite adornments, and I'm delighted to see that there are similar styles available on Etsy. The option currently linked here also has little feet(!).
