This is a vintage silver necklace with a white stone from K.C. Manufacturing of Tenefly N.J. This necklace has a 16" silver chain with a 3" extension. On the chain is a silver rectangle with a white 1" oval stone in the center. On the back of the pendant are the letters K. C. with a copyright mark in a heart shape. Research says this is the mark of K. C. Jewelry Manufacturing in Tenefly N.J., which has been in business since 1955.
This necklace needs more cleaning than we gave it, but would make a nice vintage piece.
**This necklace is not marked 925 but our silver cloth was removing tarnish.**
