Four-Stone Tiered Graduated Fire Opal Mosaic Pendant

This jewelry piece is a vertical tiered pendant featuring four graduated oval-cut stones, identified as 'fire opals' with a distinct mosaic or triplet appearance. The pendant measures approximately 1.5 to 2 inches in total length. Each stone displays a vibrant blue-green base color with intense spectral flashes of orange, red, and electric green, characteristic of high-quality lab-created or composite Australian-style opals. The stones are arranged in descending order of size, from smallest at the top to largest at the bottom. Each stone is secured in a white metal bezel setting, likely sterling silver based on the finish, which features a decorative rope-twist or milgrain border around the perimeter of each mount. The construction utilizes a classic drop design where the frames are hinged or rigidly soldered to create a linear flow. A simple polished bail is attached to the topmost stone for suspension from a chain. The condition appears excellent with no visible chips or crazing to the stones, though there is a light patina on the metal settings suggesting some age. The style is contemporary, likely mid-to-late 20th century, focused on maximizing the play-of-color through the mosaic assembly technique, which uses slivers of natural opal bonded with a base and a protective clear cap to enhance durability and brilliance.
