About us
SYNO Unique is a goldsmith's with an attached workshop and salesroom in Hameln. Owner Barbara Ziegler creates custom jewelry pieces, wedding rings and engagement rings as one-off items. Production is carried out using craft methods based on traditional techniques such as casting, rolling and forging of precious metals. Only recycled precious metals (gold, platinum) from RJC-certified suppliers are used, made in Germany; diamonds are of natural origin and come with Kimberley certification. In addition to new custom pieces, the business offers repairs, ring resizing, laser engravings (including handwriting, fingerprint, coats of arms) and the reworking of customer gold (melting down old gold). Another offering is wedding ring and goldsmith courses, in which customers make their own piece of jewelry under guidance. The location is at Wendenstraße 17 in Hameln.
