I tried looking - it is SO hard to research gold jewelry manufacturers... sorry nothing. The earrings and ring look new(er) maybe even manufactured in another country? Usually, if not gold, or if gold/filled, plated, etc. the mark beside the 10K would be something other than TJ - but if you are in doubt, you may want to have the earrings tested for metal content. I'm assuming Lind is a manufacturer's mark... wish I could be more help. Most likely the ring is sterling if marked as such. CZ center stones?
