Overview
A striking pair of mid-century costume earrings featuring large, oval-cut glass stones with a dichroic 'Aurora Borealis' coating. These stones are prong-set in a gold-tone brass or base metal frame with classic paddle-back clip mechanisms.
Story
In 1955, Christian Dior collaborated with Swarovski to create a coating that mimicked the Northern Lights. This 'Aurora Borealis' finish revolutionized costume jewelry, allowing everyday women to wear the colors of the cosmos.
Maker / Origin
While these lack a visible signature, they represent the high-quality 'unsigned beauties' of the mid-century era. Manufacturers like Coro, Trifari, and various Gablonz workshops produced similar styles using imported Austrian lead crystal to achieve this specific level of fire and brilliance.
Condition & Value
The stones show some minor surface abrasions and 'flea bites' consistent with age. The gold-tone finish on the clips appears well-preserved, though slight oxidation is visible on the earring prongs. Minor wear to the iridescent coating reduces value slightly.

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.
Best Venue
