Etymology
Origin of gem
1275–1325; Middle English gemme < Old French < Latin gemma bud, jewel; replacing Middle English yimme, Old English gim ( m ) < Latin
Explanation
A gem is a precious or semi-precious stone, or a jewel. A silversmith might experiment with adding gems to her rings and necklaces. The sparkly gem in your grandmother's fancy ring might be a diamond, while your aunt appears to prefer the polished greenish-blue gems called turquoise. If you're trained to identify and put a value on gems, you can call yourself a gemologist. Gem is from the Old French gemme, which has a Latin root, gemma, "precious stone or jewel."
