Seed Pearl Necklace and Bracelets

Just curious, based on appearances alone how old, or what age-range would you place the couple in the photograph?

Also basing on mostly the women's clothing and hairstyle, I would tentatively guess the daguerreotype was taken in the early-to-mid 1850s. I'm not an expert though, so if there are any experts out there, or if anybody knows any experts - I would love to hear their thoughts on the age of the photograph based on the subjects' styles.
