It is possible that the pendant was part of a larger item, there are a couple of patches of yellow solder and some marks where another fitting may have subtly been removed. All diamonds present and correct. The bale hinges open so it could be put onto a strand of pearls of an item with a broader suspension. The setting is unmarked but is in our opinion platinum.
