More Information

The central stone is in good order, no cracks, chips or losses. Some minor scratching and wear commensurate with age and use. A few internal fractures running just below the surface are visible to sides of the stone, visible under 10x. There is a very minor rattle from the ring when moved, indicating that the stone is very slightly loose in it's setting, however the claws are in good order and the stone is secure - some tightening may be required. All diamonds are present and in very good order, no cracks, chips or losses. Settings in good order, some scratching and wear commensurate with age and use, but no splitting, major damage or repair. Shank in good order, moderate scratching and wear commensurate with age and use, but no major thinning, splitting, resizing or repair.
