Help! SP, GF, and a flying Unicorn! What does this mean?!

Help! I’m so confused when it comes to shopping for jewelry. I just don’t know what all those terms mean! Have no fear- Super Jeweler is here! Alright, not really, but I’m a metalsmith-jeweler and I can help explain all the little symbols and arcane...

As a token of my appreciation- all orders between now and December 31st include a free pair of silver earrings. Thank you for being wonderful collectors.
