I am looking for the web site that has a pin & pendant  ( you can put
the name on the back & date the front has the birthstone )  it is for
victims killed on 9/11 it is called A quiet rememberance

I've looked at quite a few sites that offer 9/11 memorial jewelry, and
I have not found anything like the item you describe.

It would be very helpful if you could give any more details you can
remember, such as the materials used (was it gold? silver? brass?) and
whether this item might have been oriented toward remembering
firefighters, police officers, or other specific groups. The memorial
jewelry business has become quite niche-driven; there are even special
pins dedicated to Flight 93 victims.
