Buck 503 Prince with four diamonds (stones at least)
 

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?

That has to be a one-off owner-made modification. I've never see n that before.

I still have the Buck I carried all through high school. It's a slightly smaller version of the 503, I think.

Here it is. I think I bought it in 1978?

Looks like cubic zirconium

Probably is. Just seems like a lot of trouble for a pocket knife.
