Type
Jewelry (Single Earring)
Maker
Unidentified Manufacturer; likely a commercial jewelry producer of mid-market fashion accessories from the late 20th century.
Material
Sterling Silver (.925) setting with a faceted colorless synthetic stone (Cubic Zirconia, Crystal, or Glass Paste). Total weight approximately 1.5-2 grams.
Dimensions
Stone diameter approximately 8mm to 10mm; total weight estimated at less than 1 troy ounce.
Description
This is a single sterling silver earring featuring a large, round brilliant-cut colorless stone. The design is a classic solitaire arrangement, prioritizing the light refraction of the center stone. The silver frame is visible only as four understated prongs that wrap onto the crown of the stone.
Key Features
Four-prong basket setting; round starburst facet pattern on the stone; silver composition indicated by the gray-white oxidation on exposed metal surfaces.
Material & Composition
Sterling Silver (.925) setting with a faceted colorless synthetic stone (Cubic Zirconia, Crystal, or Glass Paste). Total weight approximately 1.5-2 grams.
Finish & Decoration
Polished high-shine finish; minimalist four-prong basket setting without additional ornamental engraving or embossing.
Hallmarks & Stamps
None visible in the primary image; likely stamped '925' or 'Sterling' on the earring post or the butterfly friction nut, which are not currently displayed.
Construction Details
Machine-cast basket setting; faceted stone is mechanically set with bent prongs rather than hand-wrought filigree.
Functional Features
Tension-set prongs securing a faceted stone; would originally include a friction post and nut closure.
Handle & Grip Details
Metal prongs (silver) acting as the stone grip; evidence of slight oxidation on the prong tips.
Craftsmanship Details
Industrial quality; prongs are slightly unevenly spaced, indicating mass-market production rather than artisanal bench-made craftsmanship.
Authentication Indicators
The characteristic grey-black tarnish is consistent with silver alloy (.925); the regularity of the faceted stone suggests a machine-cut synthetic rather than a natural gemstone.
Origin & Manufacturing
Likely Southeast Asia (Thailand, China) or Italy, which are primary hubs for high-volume sterling silver fashion jewelry manufacturing.
Era & Period
Modern Era (post-1970); standard design for costume and travel jewelry meant to replicate high-value diamonds.
Age Estimate
Circa 1980–2010; based on the style of the facet pattern and the standard commercial prong configuration.
Cultural Significance
Represents the democratization of luxury aesthetics; 'travel jewelry' allows the wearer to project a diamond-like status without the security risk of real gemstones.
Condition Notes
Fair to Good. The stone appears cloudy or 'sleepy,' suggesting soap residue or surface micro-scratches. Metal shows light tarnish (sulfide deposits) near the prongs. The earring is a solitary piece missing its mate.
Value Estimate
$5.00 - $15.00 USD; value is limited as it is a single earring and a common commercial design.
Care & Maintenance
Clean with warm soapy water and a soft toothbrush to remove film from underneath the stone. Use a silver polishing cloth for the prongs. Avoid immersion in liquid chemical silver cleaners which can damage some composite stones.
Similar Pieces
Tiffany & Co. Solitaire Studs (would have higher quality polishing and explicit branding); costume jewelry from brands like Swarovski (often rhodium-plated base metal rather than sterling).
Interesting Facts
Sterling silver became the 'standard' for affordable luxury jewelry in the 1970s and 80s as the price of gold skyrocketed, leading to a massive increase in the production of CZ stud earrings.
