I wondered where one gets such a pendant. Both "heart within a heart" and "double heart" necklaces searches comes up with mostly jewelry by Zales, occasionally by Kay Jewelry.

https://en.wikipedia.org/wiki/Zale_Corporation < in 2014, Signet Jewelers bought out Zale Corporation https://en.wikipedia.org/wiki/Signet_Jewelers < Signet basically owns all the diamond/jewelry companies, including Zales and Kay

https://www.hrw.org/news/2010/02/01/blood-diamond <- Diamonds are mined using human slavery (so is cobalt, which we use for cellphones, did you guys know that?)

Diamond/jewelry companies have many reasons to be friendly with PGers. They are involved at a very high level.
