How about a mindfulness retreat or a meditation course? You can find local retreat centers that offer courses in meditation and mindfulness. Alternatively, you could also get her a book on mindfulness or a set of meditation CDs or a mindfulness journal. Another idea could be to get her a subscription to a meditation app, so she can practice anytime, anywhere. Finally, if you want to go the jewelry route, you could consider getting her a mindfulness bracelet that she can wear daily as a reminder to stay present and calm.
Or you can get her a star map with the date of your anniversary.
