Inside the ring, there are hallmarks of a \"crown\" mark, \"375\", and \"F\", indicating 9-carat gold (= 37.5% gold). Additionally, the \"B.BROS\" hallmark can be seen, suggesting it was made by Berker Brothers Ltd., a long-established British jewelry manufacturer. They operated from Birmingham from the late 19th to the 20th century. A single diamond is beautifully set in the center, and the surrounding radial star-cut-like gold work is designed to reflect light and sparkle. It is a simple yet elegant and classic piece. From its overall style and finish, it is estimated to have been manufactured in the late 1970s to early 1980s. The size is 14.5 (Japanese size), which is relatively suitable for many men's ring fingers and women's middle fingers. The ring comes with a carefully maintained vintage case, making it perfect for collectors or as a gift.
