The Tank Ring: A Symbol of Strength and Glamour

Tank rings, named after the armored tanks of WWII, became fashionable in the 1940s and 1950s. Their bold, architectural lines and substantial volume symbolize power and modernity, often reflecting the strong roles women began to embrace during and after wartime. These rings are instantly recognizable for their geometric construction, broad bands, and dramatic flair. Wearing a Tank ring is a statement of confidence and timeless elegance.

Invisible Setting: The Art of Seamless Brilliance

The invisible setting (or “serti invisible”) is one of the most technically demanding techniques in fine jewelry. It allows square-cut stones—like the rubies in this ring—to be placed edge-to-edge without visible metal between them, creating a seamless mosaic of color and sparkle. This technique was developed in the early 20th century and is highly prized for the way it maximizes the visual impact of the gemstones while requiring extraordinary precision.

Rubies: The Stone of Passion and Protection

Rubies have captivated humanity for centuries, symbolizing passion, courage, and vitality. These rich red gemstones are one of the four precious stones alongside sapphires, diamonds, and emeralds. Traditionally believed to offer protection and prosperity, rubies are associated with the heart and intense emotional energy. In jewelry, their vibrant hue provides a striking contrast to gold and diamonds, as seen in this stunning vintage ring.
