This Italian ring is crafted in 18K rose gold and built around a deep black agate form with crisp diamond accents that cut cleanly through the surface.
The agate, approximately 12.75 carats, is smoothly carved and highly polished, giving the ring its sculptural volume. Set directly into the stone are three round diamonds totaling about 1.55 carats, creating a strong visual center. A subtle scatter of eighteen smaller diamonds (approx. 0.09 carats total) adds texture and light without softening the design.
Weighing 12 grams and sized at 7, this ring has real presence but wears comfortably. Marked 750 for solid 18K gold. A confident late-20th-century piece that leans into contrast, scale, and clean lines.
A statement ring for someone who prefers structure over ornament.
