This thread makes me think about a good friend whose wife passed away after battling cancer for 5 + years, leaving my friend devastated, but surrounded by people who had known and loved them both. As he cleaned up their house, giving away much of what they had collected in their many travels together, he didn't find some beautiful, valuable indian silver and turquiose necklaces he had given her over the years (he would go to Central America for a couple weeks most winters for intensive Spanish language study, and had found a silver master who's work he admired in the city where the language school was, and would get a necklace as a gift for each trip she allowed him- not needed, but appreciated.) His wife had loved them. Not too long after her memorial service, (which had over 500 folks travel to attend, telling you a lot about his wife) in a small midwest town, he ran into a local woman they had both known- someone without much money, who was wearing one of the necklaces. His wife, in the months before she died, had had this woman, and several others, admire her necklaces while she was wearing them. If she felt those women would truely appreciate them, she would simply take them off, and put them on the other woman's neck and tell them it was a gift, to be enjoyed. He encountered several of these necklaces in the ensuing months. They all felt as if they needed to explain why they had them, and treasured the memory of the woman who had given them away. My friend was fine with that.
My advice would be to store them away, and perhaps you will be lucky and find someone else wonderful. Maybe, or maybe not, they would appreciate what you have saved. Just play it by ear, whenever the time is right. And, sorry for your loss.
