Tamara,
My sympathy to you. I understand your feelings.

Even tho my mom died several years ago, this time of year is still hard for me. She died a few days before Thanksgiving, her birthday was Dec. 15, and Christmas was an important time for her, so all those things happened close in time. So this time of year is hard for me. Also, she preferred cremation, so I don't have a grave to visit or put flowers. My brother keeps her urn on a shelf in his house. He lives many states away from me, so I don't visit there very often.
Mostly, I just think about Mom, and look at pictures of her. When I go shopping for gifts, I see things and just automatically think, "Ooh, Mom would like one of those!" It just happens.
I also think about her during World Series time. She was a very strong baseball fan, and would get very excited watching ball games on TV. It was funny to watch her get involved in the games.
I think each person has to do what means the most for them. I like the idea you have of wearing your mom's jewelry. That is a good connection between the two of you.
I didn't inherit any jewelry, but some antique furniture. One small table, passed from my grandmother, to her daughter (my mom), to me, and then someday, to my daughter. That is special to me because I remember seeing that table in my mom's house, so I remember her. When my dad died, he didn't leave much but I do have his college typewriter (from the 1940s). I like having that because I know he actually touched it and used it. I also have some small kitchen items from my late grandmother. I prefer having those things because I can remember her using them to bake our bread and cook our dinner.
