Periodic Table of the Elements; Ag,
ring, made of sterling silver or sterling silver-glossy material, for reasonable cost!
This (initial test)
version is 21mm inside diameter ( US/Canada ring size: 11½ )
Sterling silver (92.5% pure)
Silver (pure) density; 10.49 g/cm³ x 0.925 = 9.703 g/cm³ sterling silver density
Ring volume, 2.15 cm³ x 9.703 g/cm³ = 20.86 grams, silver content (0.671 troy ounces,) even though total weight will be greater (7.5% of sterling is another metal - typically copper)
