Is that table green? A couple more photos would help. On a dull white background in indirect light. How about one with a part of the strand showing closeup. What is the MM? Pick a part with the most banding or irregularities.
From the variation in sizes and the couple of pearls with bands, My first guess is freshwater. Value will partly depend on the size of the pearls. It is worth more as a necklace than as a strand of pearls.
I know. I think they are very wearable pearls. They are quite pretty. Perhaps you could get them strung or learn how to knot yourself, then give it away.
They are very attractive pearls. Was this a continuous strand that broke? Or was the clasp removed? Plenty of pearls for necklace and bracelet if you wanted to wear them, or just restring as ropes are very popular now.
