Two brooches

Two old brooches I have collected and not worn. One is a gold coloured metal with large central purple stone and six very sparkly diamantes - c clasp on back. Diamantes are open set. Bar brooch also has c clasp and a gold coloured engraved top with a silver coloured panel inset with three diamantes and faux pearls - stones are not open back. Both are very pretty and sparkly but have no marks. I am not a jeweller but am just describing them as best as I can. Bar brooch is 4cm x 1cm for size comparison.
