Type
Earring Back (Butterfly/Friction Back Findings)
Purity
14K (58.5% Pure Gold). This is the standard purity for American jewelry findings due to its balance of durability and gold content.
Gold Type
Yellow Gold (Alloyed with silver and copper to provide strength and maintaining a warm gold tone).
Weight
0.05 - 0.15 grams. These findings are extremely lightweight and are usually sold by the dozen or gross in the industry.
Description
A classic essential in fine jewelry, this 14K yellow gold friction back is the workhorse of the earring world. Known as a 'butterfly' back due to its double-looped wings, it provides secure tension against a grooved earring post. While functionally simple, its presence in 14K gold ensures it won't irritate sensitive ears unlike base-metal alternatives.
Key Features
Double scroll 'butterfly' design, central puncture for post insertion, and high-tension spring metal properties.
Color & Finish
Classic Bright Yellow Gold with a High-Polish finish. The surface appears reflective and smooth, consistent with mass-produced jewelry findings.
Hallmarks & Stamps
Usually stamped '14K' or '585' on the flat circular surface of the butterfly wing. The stamp on this specific piece is too small to read from the image distance but would typically be centrally located.
Dimensions Estimate
Approximately 4mm to 5mm in diameter. Designed to fit a standard 0.8mm to 1.0mm (20 gauge) earring post.
Gemstones & Inlays
None. This is a functional mechanical finding intended to secure a primary earring piece.
Clasp & Closure
Friction-style butterfly back. It utilizes two curved 'wings' of metal that act as springs to grip the earring post through tension.
Chain & Links
N/A. Single-piece stamped construction with rolled metal wings.
Craftsmanship Details
Machine-stamped and die-struck. This process ensures high uniformity and allows the metal to be work-hardened, which is essential for the spring-tension of the wings to function without snapping.
Authentication Indicators
The rich yellow color suggests a high gold content rather than plating. Purity stamps should be looked for with a 10x jeweler's loupe on the flat face of the scroll.
Origin & Maker
Likely USA or Italy. Major manufacturers of these include companies like Stuller, Hoover & Strong, or Richline Group.
Era & Period
Contemporary (Late 20th Century to Present). This specific die-struck design has been the industry standard for decades.
Age Estimate
Modern production, likely manufactured within the last 10-20 years based on the standard scroll design and finish.
Cultural Significance
Represents the shift in jewelry from heavy, screw-back designs of the early 20th century to the more convenient and mass-produced friction post styles favored by modern consumers.
Condition Notes
Good condition. The 'wings' appear to be properly aligned. Over time, these can loosen or 'spread,' requiring them to be gently squeezed back together to maintain grip.
Value Estimate
Melt value is negligible (approx. $3-$8 USD based on current spot prices). Retail replacement value is typically $15-$30 USD per pair at a jewelry store due to overhead and shipping.
Care & Maintenance
Should be cleaned regularly in warm soapy water to remove skin oils and hair products that can build up in the tracks. Check tension periodically by sliding it onto a post; if it slides too easily, the wings need tightening.

Interesting Facts
Earring backs are the most commonly lost item in the jewelry world. Despite their small size, the global market for replacement gold findings constitutes a multi-million-dollar industry segment.
