Please view and inspect any photos closely. We endeavor to fully disclose all condition information clearly and concisely, however, please note that what qualifies as excellent condition for historical jewelry differs from modern and contemporary pieces; please take the age of the piece into account when examining the piece. Minor age wear is typical and to be expected for antique and vintage jewelry.
