Here, in Koktebel, Marina met a great love — Sergey Efron. They wandered along the shore of the Black Sea. Marina was collecting pebbles, and Sergei began to help her. And suddenly she decided: if a handsome young man finds a carnelian for her, she will definitely marry him. And so Sergei, without looking — because he was looking only at Marina, takes a pebble and hands it to her. And, of course, it was carnelian. Later, Tsvetaeva will insert this stone into a silver ring and will not part with it for the rest of her life.
