Mid-20th Century Asian Diamond Big Dipper Bi-color Gold Ring

DESCRIPTION

This is a diamond ring from the mid-20th century, crafted in 14k solid gold with parts plated in white gold, and set with seven brilliant-cut diamonds, totaling approximately 0.91 carats.

The design features five 0.15-carat and two 0.08-carat diamonds arranged to represent the Big Dipper constellation in the night sky. The diamonds are bezel-set, creating a smooth and clean outer frame that mirrors a star chart, highlighting the overall contour. The varying sizes of the diamonds add liveliness to the design, while the open-back setting allows more light to enhance the brilliance of the diamonds.

Beyond its romantic and delicate composition, the ring also exhibits intricate structural details. Some diamonds are bezel-set in white gold, adding depth to the color scheme and brightening the overall tone. Additionally, the constellation is set on a gold base connected to the ring shank, creating a layered, three-dimensional effect while ensuring a comfortable fit on the finger. The design is meticulously crafted, showcasing years of refined craftsmanship in a beautiful piece.

The ring is in good vintage condition, with normal oxidation and signs of wear. The inner shank is stamped with "585," indicating 14k gold. Since the assessment of condition is highly subjective, please click and enlarge our photos to view more detailed conditions as a basis for your judgment.
