Condition: this brooch came to me with one emerald replaced as a round cut; my jeweler has restored this round replacement with an appropriate square cut to match the existing emeralds. One diamond was off-center in its setting and thus reset and re-centered. The pendant bail loop to back was added by my jeweler via laser welder. Overall in good condition for age: the gems are preserved whole, without chips or major damages. Minor age-wear includes tarnish to the silver and tiny abrasions and nibbles to the facet junctions of stones.
