Solid 14K Gold Open Heart Filigree Pendant With Natural Amethyst Stone

Vintage heart pendant with light purple / lilac / lavender amethyst stone. Real solid 14 karat gold. It has beautiful authentic vintage filigree work, and was likely made in the 1950th or earlier. In excellent condition. This pendant is either not stamped, or I can't find it. But it was professionally tested by a jeweller and confirmed as 14 K gold.
