$45.00 - $85.00 USD

Provenance History
Unknown; typical of pieces circulating in the secondary vintage market or passed down as family heirlooms from the mid-20th century.
Art Historical Significance
The piece represents the post-war boom in high-quality costume jewelry. The use of the Aurora Borealis coating, invented by Swarovski in 1955 in collaboration with Christian Dior, dates this piece to the late 50s or early 60s when this 'rainbow' effect became a global fashion phenomenon.
Notable Features
Features elaborate filigree bead caps and a decorative 'hidden' box clasp set with a matching faceted stone, indicating a higher quality of production than standard department store mass-market jewelry.
Condition Issues
Visible wear to the iridescent AB coating on high-contact facets; possible oxidation or 'verdigris' on the brass bead caps; potential weakening of the original stringing material due to age.
Conservation Recommendations
Keep in a low-humidity environment to prevent brass oxidation. Clean only with a dry, soft microfiber cloth to avoid stripping the delicate iridescent coating. Store flat to prevent stretching the string.
