For women who have lost a child only pls?

My wife has worn an empty locket for 8 years to remember Emily, who lived a few hours before dying in mum's arms. In the past six months, she has separated from me, and found a new boyfirend. Also, our youngest child snagged her locket chain, and broke it.
Yesterday, she was sporting a new necklace. It is half of a medallion that she is sharing with her new boyfriend. I am absolutely thrilled that she has taken the step to wear a necklace other than the locket.
When we were married, I bought her a pair of ruby earrings that had a matching necklace. I gave her the earrings, but never bought her any necklaces. I figured I could buy the necklaces after she made the decision to wear something besides the locket. There is also a necklace to match rings I have bought her, and a bracelet, and etc.
Now I want to go back to the jeweler and buy the necklaces that complete the sets that I meant for her to have years ago. I don't though, want to 'celebrate' Emilys passing...suggestions?

I know that is an awful thing to go through, i gave birth to twin boys 15 weeks prem and one of them only live an hour then died. It is something you will never be able to fully get over it leaves a hole that cant be filled like part of you is missing.
I wore a Cross with my babys name on for years its been 12 years since he died. I think now she has decided to wear different necklaces anything you buy will be fine,because i found you think of them in other ways instead.
