Title: Rare Earths

Description: In the collection below, find materials related to rare earth elements, a group of 17 elements composed of scandium, yttrium, and the lanthanides. These abundant elements, characterized by similar geochemical and magnetic properties, are mined for a variety of uses including magnets, alloys, glasses, and electronics. The diverse collection of materials found below demonstrates the range of uses for rare earths throughout the twentieth and twenty-first centuries. Browse the topic to find materials related to fine art, lasers, cathode ray tube televisions, the first incandescent lights, and more!

@apinkney0696 I'm going to change "In the collection below" to "In this collection" -- we don't want words in there that assume a certain page layout, we may re-use the description in other contexts.

(Other featured topic descriptons tend to say "This digital collection features…" instead of, as here "In the collection below, find materials…", btw. We could re-use that wording generally, "This digital collection features materials related to rare earth…" )
