Stunning Natural Baltic Amber Lump Necklace

Vintage genuine Baltic natural amber necklace featuring a huge chunky nugget/ lump pendant worn on a silver metal chain, worn overhead, the chain is hallmarked but I wasn't able to find the maker based on this mark, the tone is best described as cognac with natural imperfect structure and various inclusions, absolutely gorgeous! Condition: overall in great condition for the age, from a non-smoking environment.
