Vintage DRGM stamped Schreiber & Hiller Art Deco channel set paste sapphire blue rhinestone geometric machine age bracelet, unusual colour

Wonderful vintage Art Deco bracelet in silver tone with geometric, three dimensional design and scores of channel set rhinestones in an unusual blue colour. 

Made by Schreiber and Hiller in Germany as we now know, these pieces are beautifully and intricately engineered. The snake-like links of the bracelet follow the curve of the wrist and it feels so comfortable to wear. It fastens with a secure push-in clasp hidden in the ends of the bracelet.

The length of the bracelet is hard to show in the pictures as it will not lay flat on its own due to the construction. However, I can confirm that the length is an extremely slim fitting 6 3/4 inches, so please check wrist measurements carefully. This example is stamped DRGM with a patent number 44385251 as is often the case with these Schreiber and Hiller pieces.

The final picture shows a copy of the 1930 patent submitted by A Hiller to produce these channel set designs (fig 3 shows the three sided half-hexagonal pattern similar to that used in this bracelet). The bracelet is in good vintage condition for its great age but please look at all the photos very carefully.

I adore this website for such detailed information about the manufacturer and their designs:
