Mid-Century (1950s-1970s) based on the prong-setting style and metal patina

Condition
Good to Very Good. The stones appear intact and the plating shows minor age-related patina/discoloration on the back which is common and often preferred by collectors of vintage costume jewelry.

Moderate. Blue is a popular color for collectors, but unbranded costume jewelry earrings are a high-volume/lower-margin category.

Lovely pair of vintage MCM cluster earrings featuring deep cobalt blue faceted glass rhinestones. Each earring is set in an antiqued gold-tone base metal with secure prong settings.

Key Features
Rich cobalt blue colorway, high-quality prong-set stones (not glued), classic mid-century cluster silhouette, versatile size.

Construction style (prong settings) and patina are consistent with mass-market vintage costume jewelry from the 1960s. No designer hallmarks visible. Confidence level: High (as genuine vintage costume).
Flaws to Note
Slight oxidation on the earring posts and back of the setting; one post may be slightly bent but still functional. Rhinestones should be checked for tightness.
Selling Guide
Where to Sell
Etsy (best for vintage), eBay (good for global reach), or Poshmark (best if bundled with other vintage accessories).
Selling Tips
Use keywords like 'MCM', 'Cobalt Blue', 'Rhinestone Cluster', and 'Prong Set'. Photograph them on a clean white background or a jewelry bust to show scale. Mention they are 'pierced' specifically. If selling on Etsy, emphasize the 1960s aesthetic.
