Are these items significant and how?

I think you're Jesus reincarnated.

You should get together with Chickenfat.

20 years ago? wow. Anyway, the #7 is very significant in the Bible and represents completion. In the book of Revelations (the last book of the Bible) there is reference to 7 eyes and 7 trumpets. It would take me millions of pages to explain the representation and symbolism of Revelations as it is very reflective of society and government in that time period as well as Christianity and the end times.

As far as the stone, it is representative of the stone that was placed in front of Jesus' tomb when he was crucified. It's white because white stands for purity-everyone is cleansed through the forgiveness of Jesus Christ. He is called many things including "the lamb". This is because of his innocence and purity and the lamb was representative somehow of culture at the time Jesus was living.

About not showing it to anyone---that's weird. I don't know why she would say that since Christians want to spread the word of God.

I would ask Robert Langdon. Well, maybe not, he was wrong in almost all of his assumptions about history and that is proven. I would show it to someone like an antique dealer. They tend to see weird little trinkets quite often

You've kept them this long. You might as well hold on to them.

I have no idea what they are supposed to symbolize or represent,

although from your description they sound biblical.

I would hand them over to homeland security

wow!!! that signifies Christ's second coming!!! for more information...read Revalation (in the Bible) all of those things are found in Revalation...
