This is a specialized industrial stepless ear clamp used primarily in automotive or plumbing applications to secure hoses. It is not a piece of jewelry or a gold item. The '110.5' stamp indicates the open diameter size, not a gold fineness. Its design ensures a 360-degree seal through its unique overlapping inner band.
