This extraordinary oversized geometric cocktail ring, crafted in Italy during the postmodern period in 1980, is a bold statement piece of remarkable artistry. Designed with sharp triangular and faceted shapes, it is meticulously crafted in solid 18-karat yellow gold with a high-polished finish. At its center is a bezel-set natural Brazilian blue topaz, pentagon faceted with a step cut, weighing approximately 65 carats. Enhancing the design are 28 linear cabochon-cut stripes of natural black onyx in inlaid settings, alongside 15 geometric beveled and flat-cut pieces of natural white agate. Weighing an impressive 55.20 grams (35.39 dwt), the ring measures 48 mm by 42 mm (1.89 x 1.65 inches) with a 13 mm rise above the finger. Sized at 6, it can be adjusted upon request. This striking piece is a true testament to the bold creativity of postmodern Italian design. Very good conditions. Upon Request, Auction House may provide ring resizing or/and appraisal. This will carry an additional cost. Appraisals are made by our in house GIA certified Gemologist.
