Buck 503 Prince with four diamonds (stones at least)

[Lynn]

OK, this should be my last oddball questions for the week.

In the same lot of stuff I acquired the oddball Craftsman ratchet, there were a couple of nice little pocket knives with locking blades; one is a Gerber, the other a Buck 503 Prince with Rosewood.

The Buck knife has (or had.... two fell out) stones that look like diamonds imbedded into the metal ends.

I cannot find anything like this on the web.

You can see where little holes were drilled, stones inserted and then four stake marks to set the stone.

Have a hard time believing someone would do that with real diamonds.

One off?
