Curious to find out about these religious items

Size?
They look like rosary crosses, like this one:


Ca 1900, I think. The one on the right could contain a relic, could we see a close-up of the contents?

 

The best I can manage at the moment I'm afraid...

 

It is Italian, from Rome.
Lignum Arboris S.P.D means the wooden inlay is made from the tree planted by st Dominic, Sancti Patris Dominici. Agnus Dei is the Lamb of God (Christ).

The tree of St Dominic is an orange tree in the cloister of Santa Sabina all'Aventino, next to the Dominican order's headquarters in Rome.
Here is the story of the tree:

Thank you, that's really interesting.

 

Found one on ebay, don't know if the asking price is realistic:

A.J. your knowledge and your ability to find knowledge is amazing.

 

Much more than I thought it was worth. Knowing the history of them, it's unlikely I'll sell them. I may pass them on to a religious friend.

 

It does not come from the orange tree planted by St. Dominic, but rather a different miraculous tree associated with him. St. Dominic gave a cypress stick to Blessed Reginald of Orleans. Reginald planted the stick and it grew into a cypress tree.
