Vintage Cultured Pearl Necklaces

These were inherited. Sea Gem brand - after researching this brand, they were a company which sold high quality pearls in Canada. These were kept in their original box and case. The box is marked "cultured pearls". I don't know if these are fresh or saltwater pearls. I haven't had these valued professionally, so they could be worth a significant sum of money. After some research, I suspect they are worth much more than what I'm asking for the set. I performed a simple test to determine their authenticity, and both necklaces passed. As they were inherited from someone with some equity, would prefer these go to someone who will wear and appreciate them v. someone who will resell them. Both off white, one more cream in colour. Pearls are not perfectly consistent, but close to. They will fall below the collar bone. Note: clasp is missing on the necklace with the gold tassels. However, a clasp can be added very cheaply by a jeweller or even by purchasing a clasp online and using a fine gauge tool. Attached some styling ideas I adore. Thanks for looking!
