An antique locket charm dating to 1900, crafted in 15K gold and adorned with vibrant blue guilloché enamel and a single rose-cut diamond. Guilloché enamel, prized for its luminous depth and intricate engine-turned patterns, was a hallmark of fine turn-of-the-century jewelry. The rose-cut diamond is a later replacement that complements the original design while preserving the charm's elegant character. The locket opens as intended, offering space for a treasured photograph or memento.
The locket measures approximately 0.8 inches from the top of the bail to the bottom and 0.55 inches wide. It weighs 2.65 grams and remains in great antique condition with the enamel well preserved.
Gemstone identification has been confirmed using Raman spectroscopy, a non-destructive analytical technique that provides a precise chemical fingerprint to verify authenticity.
Metal authenticity has been professionally verified using XRF (X-ray fluorescence) analysis and traditional jeweler’s acid testing, confirming solid 15K gold construction.
