Sculptural avant-garde ring, Europe (likely Italy or England), circa 1960, crafted in solid 14K yellow gold with high polish. Features pure geometric forms—a cube and a floating 10 mm natural lapis lazuli sphere—reflecting Zero-group concepts of light and space. Expertly constructed as a miniature model, fastened with two screws. Measures 14 x 14 mm (0.55 x 0.55 in), rises 15 mm, size 6.5 (resizable), weighing 11.95 grams. Stamped with maker’s mark, gold assay, and signed “14K TH.” Very good conditions. All our diamonds and colored gemstones are naturally earth-mined. Any synthetic (lab-grown) stones will be clearly indicated in the description. 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.
