A cool blue emerald-cut stone sits prong-set in warm gold, flanked by small bow-shaped shoulders for a touch of vintage sweetness. Signed by Esposito, a maker known for well-made mid-century gold filled pieces, this ring has the weight and finish of costume jewelry built to last. The adjustable band means an easy, comfortable fit. A quiet, classic piece that wears well on its own or stacked.

Diamond-cut rays fan outward from a small center flower, framed by an open, elongated silhouette that catches light from every angle. The wide, textured shoulders taper into a slim band, giving the piece presence without weight. Unsigned, but finely cut, with the kind of intricate openwork more often reserved for finer goldwork. A small, sculptural statement for the hand.

A wide, asymmetrical leaf unfurls across the finger, its surface covered in fine radiating ribs that catch light from every angle. Cutting diagonally across the center, a smooth inlaid channel holds five small round rhinestones in a gentle curve — the single point of sparkle against an otherwise all-gold composition. The leaf curls slightly at its edges and tapers to a point at the lower corner, giving it a naturalistic quality that softens what could otherwise read as purely geometric. Leaf motif rings in this style were a recurring presence throughout the 1970s and into the 1980s, when nature-inspired forms dominated costume jewelry and gold tone metal was the default. This one is unsigned but well-made, with good weight and clean detail.

Nine round prong-set crystals appear to float across an irregular organic landscape — a wide, open-worked band of molten-looking gold tone metal that bubbles and branches like coral or cooling lava. The stones sit at varying heights across the top, their silver-tone prongs contrasting against the warm gold beneath, which gives the whole surface a two-tone quality that feels intentional rather than incidental. The underside of the band continues the texture, leaving no part of the ring unfinished. This is squarely in the Brutalist and organic modernist jewelry tradition that defined the 1960s and early 1970s, when cast metal jewelry rejected clean lines in favor of raw, elemental form. It wears like a piece of sculpture.

A sculpted ribbon bow spreads wide across the finger, its looped and gathered folds rendered in warm gold tone with fine engraved line detail across each wing. At the center, a small oval cabochon in muted blue — somewhere between slate and periwinkle, with a slightly speckled, matte surface — anchors the whole composition without competing with it. The bow is generous in scale but sits closer to charming than costume, the kind of ring that reads as intentional rather than loud. Avon produced bow motif jewelry throughout the 1980s in consistent quality, and this one holds up — signed on the interior shank and in very good condition for its age.

A faceted oval stone in deep sapphire blue sits flush in a bezel setting, flanked on each side by a ribbed fan of silver tone metal that tapers smoothly into the shank. The silhouette is architectural — substantial without being heavy, with the fluted shoulders giving it a sculptural quality that reads closer to Art Deco revival than costume. The stone shifts between inky navy and bright aqua depending on the light, which is most of the reason to wear it. Rings built around a single bold stone and a strong geometric setting were a recurring theme of 1980s costume jewelry, and this one holds that moment with quiet confidence.

A single cream faux pearl sits at the center of two sweeping bypass bands, each set with a row of clear crystal rhinestones and edged in fine milgrain detail. The movement is elegant and slightly sculptural — the crossover design lifts the pearl off-center just enough to feel dynamic rather than stiff. Signed on the interior shank, it comes with the provenance of a recognized name and the wearability of a piece that never fully goes out of style.

Materials
Gold tone base metal, simulated pearl, clear crystal rhinestones

Details

• Era: 1980s
• Maker: Avon (signed on interior shank)
• Style / design notes: Bypass crossover setting; two rhinestone-paved milgrain bands cradling a central faux pearl
