Citrine and Diamond Ring by Ostag Studio New York, Circa 1980s

A bold and sculptural 18k yellow gold ring by Ostag Studio, New York, exemplifying the expressive, high-volume aesthetic of 1980s jewelry design.

The ring is centered by a richly colored citrine weighing approximately 3.00 carats, bezel-set within a substantial, softly contoured gold mount. The warm amber tone of the citrine is enhanced by the surrounding gold, creating a harmonious and luminous palette.

A gently curved line of round brilliant-cut diamonds totaling approximately 0.68 carats sweeps across the surface, adding contrast and a refined sparkle to the otherwise matte-textured gold finish. The interplay between the brushed texture and polished accents gives the piece depth and a distinctly architectural presence.

The wide, tapering shank and sculptural silhouette make this ring both a statement piece and a comfortable, well-balanced design.
