Part 11 of an occasional series about rings in my Etsy shop that remind me of things.
Ring:

Vintage enamel and sterling silver ring by Joid’art of Barcelona, Spain. For sale in my Etsy shop: click on photo for details.
Thing:

Lichen Xanthoria parietina. Photo by James Lindsey at Ecology of Commanster.
UPDATE: The ring is now sold. Sorry!
So far I have had rings that remind me of an Iron Age hillfort, an alien spaceship, a cream horn, a radio telescope, Noah’s Ark, an octopus tentacle, spider eyes, Pluto and its moon Charon, the rings of Saturn, and The Starry Night by Vincent Van Gogh.
