The diamond and ruby brooch is in overall good condition. The diamonds are bright and lively. Nicks and small chips can be seen to the central diamond. The diamond drop also has a small nick to the girdle. It may deteriorate with a heavy bang. Small scattered inclusions can be seen under magnification under the table facet. Fire fractures and inclusions can be seen within the diamond surround. Some fractures are running through the stones. One is surface reaching. Chips and nibbles can also be seen to the girdle edges of these stones.  The rubies have a red to pinkish red hue. One has a deeper hue compared to the others. Light nicks and chips can be seen to the rubies. Minor scuffs can be seen to the brooch, in keeping with age. All settings will need attention, as several of the claws have worn thin.

Dimensions of central diamond: 8.90 by 8.80 by 4.6mm

Diamond drop dimensions: 8.80 by 8.80 by 4.90mm.
