Italian Modernist 18 Karat Gold Malachite, Onyx and Diamond Geometric Cube Statement Ring, Circa 1980

A striking and highly sculptural Italian modernist statement ring crafted in 18 karat yellow gold, showcasing an ingenious geometric cube design accented with rich green malachite, polished black onyx and four brilliant-cut diamonds.

The architectural composition creates a captivating optical illusion, with four interconnected cube motifs arranged in a three-dimensional formation that reflects the bold design language associated with the finest Italian jewellery workshops of the late 1970s and early 1980s.

Substantial in both scale and weight, this exceptional ring possesses a confident presence on the hand, making it an ideal piece for collectors of modernist, contemporary and designer-inspired jewellery. Its sculptural form and impeccable craftsmanship exemplify the innovative creativity for which Italian goldsmiths are renowned.
