Passed down for generations

The bracelet has been passed down for generations.  It came from my mothers side so it may be from Scotland.  It has .925 on it and the stone in the middle I have no idea what it is.  The rings have also been passed down from great great grandparents one has a turquoise stone in it and I think it says sterling silver although it is not that color. It has two crossing arrows and an arrow head underneath it. The cameo also has been passed down. It is gold 18kt it also says (I think) HGE after the 18kt.  All have been passed down by the same side of the family.  My great grandma is from glad I as well as my great grandfather. You probably won't believe this but his name was Duncan Mcloude. Any info on any of the items would be greatly appreciated.
