Overall condition good. Minor surface wear in keeping with general wear. Glue residue can be seen to some of the seed pearls. The diamonds are bright, lively and well matched. Unhallmarked. Light nicks and chips can be seen to some. Fine feathers and fractures can be seen under magnification.

Without the aid of laboratory equipment, it has not been possible to determine if these cultured pearls are from a fresh or saltwater source. Individual size and setting prevents accurate colour and clarity assessment. Due to the closed back settings and nature of the rose-cut it is not possible to calculate a (total) diamond weight. Based on the surface spread alone of the diamonds, they appear to occupy the same surface space as diamonds with an estimated total weight of 0.42cts, however it is important to note that as it is not possible to gauge the depth of the stones, this estimated weight does not reflect the true weight of the diamonds in any way.
