Art Nouveau Amethyst, Pearl & Enamel Brooch, Watch Pin, 14K

About This Brooch:

This antique Art Nouveau brooch features a stunning amethyst and an old European cut diamond, adorned with iridescent enamel. The beautiful design and vibrant bloomed gold exude femininity and evoke sentimental feelings. Originally used as a watch pin, it now adds a touch of elegance to any outfit.

Bloomed gold is a historic surface treatment in which an acid wash was used to bring a thin layer of pure gold to the surface, creating a soft, velvety matte finish. Most commonly seen on Victorian and Edwardian jewelry, it can also be found on some vintage pieces. This delicate finish remains highly sought after by collectors today.

Condition:

There are tiny scratches on the amethyst and is likely a recent replacement. The enamel is in good antique condition. The 10K clasp is a replacement. The entire brooch is 14K and was originally treated with an acid wash to produce a richer gold color.
