The pearls in photos 1 and 2 are dyed Chinese freshwater pearls. Their value is low.
I can't make the 3rd photo out well enough to comment on those.
Sorry, this is a pearl forum-- I don't know anything about jade! You could try posting the jade photos on the Colored Gemstones forum on Pricescope.com.
Discuss all other natural gemstones here: post pictures of your favorite stones or jewelry, chat about cut styles, and learn about how to pick the perfect gem.
