Seed Pearl Necklace and Bracelets

[Steve]

I know I'm repeating myself from an earlier comment, but I would really like to hear people's opinions on this question. Judging just by looking at the image, and not inferring anything by any outside assumptions (like who the people in the image may be and when you think the photo was taken), how old do you think the two people in the image are? What age range, in their 20's, 30's, 40's, 50's? Note that the man has a slight graying of his beard but I don't think I can see any other graying hair on the man and woman.
