We were absolutely in awe of this piece when we found it. It is a vintage sterling silver dress clip from the renowned German jewelry company Knoll & Pregizer.
The hallmarks went unidentified for many years, lost to obscurity, until recently.
For the past several years, Knoll & Pregizer's sterling silver and paste pieces have become some of the most collectible in the costume jewelry world.
This is both due to their incredible rarity and beauty.
The company was founded in 1887, in Pforzheim, Germany, by Theodor Eberhard Friedrich Knoll and Friedrich Pregizer; Pregizer was later replaced by Carl Knoll.
The company closed in 1975.
This extraordinary dress clip is a stunning example of the company's Art Deco style. The front is comprised of a single, slightly domed sterling circle.
The circle is accented with dozens of inset clear paste gems in varying sizes.
Each stone is framed by delicate millegraine. Some of the stones have yellowed slightly over the years, though this is to be expected.
The reverse of the circle and the reverse of the clip feature tiny "teeth"; these helped grip the fabric of a dress thereby keeping the clip securely in place.
You will also find a stamped "5" on the reverse of both the decorative circle and clip component. This is likely a style number.
The clip also boasts a lovely pierced design and exhibits two important maker's marks, the first of which reads "Sterling".
This is followed by the company's "KP" hallmark.
As you can see, the sterling shows some minor surface scratching and a light patination.
There is darkening to the face of the clip as well as a few areas of discoloration in the paste gems.
We did not polish the silver or clean the paste gems. We are confident it will clean, but leave it to the owner for their preference.
Overall, the clip remains in good vintage condition.
