This is a gorgeous David Yurman Amethyst and diamond 18k yellow gold enhancer from the Chatelaine Collection. It is rare and no longer available. This enhancer is in perfect condition. The amethyst is approximately 13mm wide and 22mm long. The facets really catch the light. The enhancer is 1 1/2” tall including the bale. The bale opens to accommodate a chain up to 3mm wide. It is hallmarked D.Y. 750 on the back of the bale. The bale can detach from the pendant. This sale does not include a chain. I show it on a DY Madison Link 20” chain for illustration purposes only. I have added a picture of this gorgeous pendant next to a DY Amethyst amulet that retails for $1100 so you can see the value in this piece. This stone is about twice the height and this pendant has diamonds.
