In addition to your contact information, jewelry tags and earring cards should also list the materials (stones, metals, etc.) used in the piece of jewelry.

And because jewelry is an emotional purchase, consider adding any “romantic” information that would be interesting and increase the perceived value of the piece.

For example, “Made from vintage glass beads discovered in a 50-year-old trunk”, or “One-of-a-kind bone pendant hand carved in Alaska”, or “Hand made in a traditional Celtic pattern”.

Include a sentence about your craft, if that would be interesting to customers.

And tradtional gemstone lore related to the jewelry item is another thing you can write on display cards to increase the sentimental value of the piece. However, anything in your gemstone lore that sounds like a medical claim should be accompanied by a disclaimer stating that your jewelry is not intended to take the place of professional medical care.
