That's some big shoe to fill!
My College Ring for an Associate in Liberal Arts - Pre-Engineering. It is a color change Spinel mounted in 'Siladium', a silver simulant of alloyed Stainless Steel and Palladium, The Color change of the Spinel is a limited one. At just the right angle in sunlight, one of the side facets shines bright red! It moves around from facet to facet but only one at a time switches to a deep ruby color. Dang you can read the year (1983) and thus guess my age. Oh well, nothing like a little age on a man, right ladies?
