How do I address this with SIL's

My mother in law died over the summer. It was sudden and very unexpected. I'm married to her eldest child and only son but she has 2 daughters as well. One my age and the other 2 years younger than me.

A little back story, my MIL had a pill problem. Not sure exactly what it was because no one ever directly found it or asked my father in law who was helping her get what she wanted. I've been a part of this family for 12 years, I love her and I miss her beyond words. I needed her, we all needed her and she's gone. Out of everyone in the family, I was the only one who wanted to confront her and attempt to stop this cycle of abuse and get her the help she needed but I was vilified for it. Now we will never have the chance because she is gone. She was only 60!

Anyways, her daughters have been able to get things to remind them of her, little things like her purse or a sweater, things like that. I've not but I only wanted a few things that need to be addressed all of us together I think. She has this gigantic collection of recipes that I just want a copy of. I also wanted the last jewelry set she was given, but here's why. She confided in ONLY me what she wanted for her 60th birthday. She wanted a pair of diamond earrings, so I told the family and we put money together and got them for her. She wore them everyday till she died. Then for Christmas I got her a necklace to match her earrings and she adore it as well. Mother's day, 3 weeks before her death, I picked out a diamond bracelet to match her necklace and earrings. She was shocked as she never had a gift like this before. I want this set for 2 reasons the first because it came from a heartfelt conversation between she and I. The second is because her daughters will pick out things they have seen her wear their whole lives and this is something that really came from my heart.

It will be a year she was gone in June, how do I address this? I really wish I had something small now to hold or touch of hers but I also want the cookbook and jewelry!

To clarify, I don't blame them for her death nor have I brought up her addiction issues since her death. She died of a heart attack but had been abusive to everyone in the family except me. I only wanted to get her help when she put my children in danger. Because I wanted us to come together and finally get her the help she needed, my SIL's were mad at me. I'll add this was after her birthday and Christmas, 3 months before her death. So it was raw.

She had been very vocal about her really nice jewelry, things she's gotten from her mother, her mother in law and over the years. I wouldn't ever ask for ANY of that. It means soo much to her daughters and absolutely nothing to me. I only want the 3 items that are meaningful to the relationship she and I had, especially since I was the one to get them for her. I'll add my husband also want me to have that set since we gave them to her.

I'm not asking if I should or shouldn't ask for them, I'm asking how would you word the conversation. Because make no mistake, it is going to happen at some point. I'm just missing her so much more and I have nothing but pictures. I've been in the family for over a 3rd of my life and I'm as much a part as anyone else.

I forgot to add that we haven't divided up anything yet and my FIL did say she wanted the 3 of us girls to pick what we want of her fine jewelry. But I will reiterate.. I DONT WANT ANY of her jewelry from her mother or mother in law. She got nice things from them when they died. NONE of that do I feel should go to me at all. I ONLY want the things I bought her and the matching earrings. I also bought my SIL's matching bracelets that go with their mother's so they don't really need that. None of them have daughters or will have daughters and I have a daughter that is her namesake.

After seeing your comments, I think many of you don't seem to understand or comprehend how family's work. I'm her only daughter in law BUT she was like a mother to me and I was closer to her than her daughters in the last few years. They would literally come to me to figure out what was wrong with mom. So YES I am as much a part of this family as her BIO children, that's how our family works.

I'll have my husband ask them when we can divi up the stuff but I don't even want to used the term divi up. I just want the 3 things listed. I don't think that's unreasonable AT ALL nor does my husband, who actually wants our daughter to have more than that. Since they don't have daughters, it is likely she will inherent their stuff anyway but I'm not really worried about that at all.

I just miss her and would like something I could look at everyday that belonged to her. I'm grieving too, we all are.

Final edit***

To all those suggesting it's a "money grab" or fishing through her "estate" that's all laughable. My husband and I are millionaires by our own making and hard work. We paid of their mortgage and bought them a boat. The only reason we pooled money for the earrings is because they wanted to contribute to that gift. I purchased the necklace and bracelets worth 2k each. That's nothing for us. It is about my relationship with my mother in law. How my gifts to her made her feel and how I will feel wearing them.

Some of you "women" suck at looking at the question and answering it without putting your personal emotions into it. This isn't about YOU or YOUR family. Smh
