Saw that ad for their jewelry and as a designer myself I could not fathom knowingly using such similar designs in my work. If the artist never knew she was using a child pedo symbol she must have been told by someone....

I tried to dig up something on the Open Hearts Foundation as well, run by Jane Seymour, but not much time right now, will investigate further later.
Could be a dead end, but imm suspicious. Good luck voat.
