I have a pair of quartz crystal earrings that I love, but tend to lose frequently. It must be their power that I always manage to find them, even after one has fallen out of my ear in an odd place.
He probably didn't know what it was, but I also have a necklace with a polished rose quartz that my ex gave me. I don't have as much attachment to it as I do the earrings, but I do seem to be very aware of it when I do wear it. I don't know if that's for sentimental reasons, or because the chain usually gets stuck on my magnetic name tag at work. I had hoped it would affect the love between my ex and I, but it didn't. Maybe he should have been the one in possession of the stone. Anyways... I would feel guilty wearing it now in hopes to attract new love, so I probably won't wear it much unless it would look good with an outfit, and I never wear pink.
