Part 18 of an occasional series about rings in my Etsy shop that remind me of things.
Ring:

1970 amethyst modernist sterling silver ring, hallmarked in London. For sale in my Etsy shop: click on photo for details.
Thing:

1:60 scale wooden model of a screw propeller of the SS ‘Great Britain’, the magnificent and innovative ship designed by Isambard Kingdom Brunel, and built in 1843. The ship is now a museum exhibit at Bristol; this model is in the Science Museum in London.
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, The Starry Night by Vincent Van Gogh, some lichen, the stepped Pyramid of Djoser at Saqqara in Egypt, the Quality Street lady, a herb knife, a sea anemone, an Iron Age miniature votive shield and the Mayan Temple of Kukulkan at Chichén Itzá, Mexico.
