White gold Teka brooch

This is a first time for me, a white gold brooch made by Theodor Klotz / Teka. I found this in a thrift
shop mixed with other brooches. This thrift store doesn't look at marks, they priced this brooch the same
as the sterling broches.
I never found a white gold brooch before.

More info on Teka found on vintage-Jewels:
TEKA (THEODOR KLOTZ)
Teka was a German jewelry brand that was founded in the forties in Pforzheim, the jewelry city of Germany. The company was led by the renowned designer Theodor Klotz. Most of the jewelry was made of silver. In the sixties and seventies the company began to make excellent modernist jewelry. The modernist designs were very progressive for that time. The jewelry is relatively scarce but still reasonably affordable.
