Description
An authentic Victorian heart-shaped pendant crafted in rare 15K gold. The hallmark '15 CT' identifies this as a piece of British heritage jewelry. The reverse features a distinctive textured finish that provides a beautiful contrast to the polished edges, reflecting the era's focus on sentimentality and fine metalwork.
Key Features
The '15 CT' hallmark is the most significant feature, immediately dating the piece to a specific 78-year window in British jewelry history.
Color & Finish
Deep honey-yellow with a textured 'bloomed' or sandblasted finish on the reverse; the surface shows a natural matte patina characteristic of age.
Hallmarks & Stamps
Stamped '15 CT' in a raised rectangular cartouche. This is a classic British hallmark used before the 15K standard was retired and replaced by 14K in 1932.
Dimensions Estimate
Small to medium, approximately 15mm x 12mm; standard size for a sentimental Victorian pendant.
Gemstones & Inlays
None visible on the reverse; the front likely features seed pearls, turquoise, or a personalized engraving typical of the era.
Clasp & Closure
Attached via a circular jump ring and a tapered bail; the jump ring shows signs of hand-soldering.
Chain & Links
The visible chain appears to be a basic cable link, though it may not be contemporary to the pendant itself.
Craftsmanship Details
Hand-finished casting with a textured reverse to hide surface imperfections and provide a soft luster. The jump ring is hand-soldered for security.
Authentication Indicators
Raised '15 CT' stamp is consistent with genuine antique dies; the color of the gold matches the expected higher-copper content of 15ct alloy; natural age-related tarnishing in recessed areas.
Origin & Maker
Likely United Kingdom. The 15ct mark was a British Commonwealth standard specifically used for high-quality jewelry production.
Era & Period
Late Victorian (c. 1854–1901). The 15ct stamp and the heart shape are quintessentially Victorian romantic jewelry indicators.
Age Estimate
Circa 1880–1910 based on the stamping style and the texture of the gold casting.
Cultural Significance
Heart jewelry in the Victorian era was deeply symbolic of love and 'Mizpah' (emotional bond). 15K gold was often reserved for the middle and upper classes as a step above common 9K gold.
Condition Notes
Good antique condition. The hallmark is crisp and deep. There are micro-scratches consistent with long-term wear and some oxidation near the solder joints. Grade: Very Good (Antique).
Value Estimate
The value is primarily in its collectible antique status rather than weight. Estimated $250 - $450 USD depending on the design of the front side.
Care & Maintenance
Avoid modern ultrasonic cleaners which may damage internal locket components or fragile settings on the front. Clean with a soft jewelry cloth and warm soapy water only.

Interesting Facts
15K gold is a 'discontinued' purity. It was primarily used in the UK and was eventually phased out in 1932 because 14K was more internationally recognized.
