Type
Jewelry (Earrings)
Maker
Unidentified commercially manufactured jewelry workshop. While lacking a visible brand logo, the mass-produced nature of the friction backs suggests a retail jeweler or department store origin rather than a bespoke silversmith.
Material
Metal is likely 14k white gold or sterling silver (925). The stones appear to be light blue aquamarine or blue topaz. The friction butterfly backs are a white metal alloy designed for tension.
Dimensions
Estimated gemstone size: 5mm to 6mm (approx. 0.50 - 0.75 carats each). Total weight likely under 2 grams.
Description
These elegant stud earrings feature a pair of round or cushion-cut light blue gemstones, reminiscent of clear ocean water. Set in clean, minimalist four-prong baskets, the design allows for maximum brilliance. The cool white tone of the metal provides a sophisticated contrast to the icy blue of the stones, making them a versatile accessory for both daily wear and formal occasions.
Key Features
Four-prong basket setting, notched security posts, friction-fit butterfly backings, and vibrant transparent light blue faceted stones.
Material & Composition
Metal is likely 14k white gold or sterling silver (925). The stones appear to be light blue aquamarine or blue topaz. The friction butterfly backs are a white metal alloy designed for tension.
Finish & Decoration
Polished high-shine finish. The decoration is minimal, focusing on the four-prong basket setting to maximize light entry into the faceted gemstones.
Hallmarks & Stamps
Marks are not legible in the provided image. Typically, hallmark stamps would be found on the earring post (stem) or the flat surface of the butterfly back, usually stating '14K', '585', or '925'.
Construction Details
Machine-cast basket settings with pre-fabricated posts soldered to the base. Prong-set stones. These are characteristic of mass-market commercial jewelry production.
Functional Features
Tension-based friction backs (butterfly nuts) that slide onto the notched posts to secure the earring to the earlobe.
Handle & Grip Details
Functional grip provided by the curved 'wings' of the butterfly backs, designed for easy manipulation by fingertips.
Craftsmanship Details
Commercial grade craftsmanship. Precise machine casting and soldering. The focus is on functionality and affordability rather than unique hand-wrought artistry.
Authentication Indicators
The design corresponds with standard retail jewelry components. Authentic fine jewelry hallmarks would be required on the post to confirm metal purity beyond a visual estimation of 'white metal'.
Origin & Manufacturing
Likely manufactured in a large-scale facility in the USA, Thailand, or China. The production follows standardized industrial jewelry-making traditions.
Era & Period
Contemporary/Modern (late 20th century to present). The design is a timeless standard that has remained unchanged for decades.
Age Estimate
Circa 1990-present day. The style and component type are currently in high-volume production.
Cultural Significance
Solitaire studs represent the standard for 'first fine jewelry' gifts, often given for birthdays, graduations, or as bridesmaids' gifts, symbolizing timeless simplicity.
Condition Notes
Fair to Good. Visible moderate tarnish and grime on the metal surfaces, particularly around the prongs and the interior of the butterfly backs. One earring shows potential heavy oxidation (blackening) near the base of the post. Stones appear intact but may require cleaning.
Value Estimate
Market value is $40–$150 if sterling silver and blue topaz; $150–$450 if 14k white gold and aquamarine. High variability based on metal purity and gemstone authenticity.
Care & Maintenance
Clean with warm water, mild dish soap, and a soft toothbrush to remove accumulated skin oils and dust from behind the stones. Use a silver polishing cloth if the metal is sterling silver. Avoid ultrasonic cleaners if the stones have significant inclusions or are dyed.

Interesting Facts
Light blue stones like Aquamarine have been symbols of youth and health for centuries; in jewelry history, blue topaz became a popular, more affordable alternative to aquamarine in the late 20th century due to advancements in irradiation treatments.
