Pre-Owned Luxury Jewelry
Roberto Coin Jewelry
Inside every Roberto Coin piece — against the skin, invisible to the world — a small ruby is set by hand. You feel it. Only you.
Inspired by ancient Egyptian and Burmese traditions of wearing a ruby as a talisman of love, joy, and protection. The hidden ruby has been Roberto Coin’s signature since the debut Appassionata collection in 1996.
Pre-Owned Roberto Coin — Italian Goldsmithing at Its Most Personal
Roberto Coin was born in Venice in 1944. He spent his early career as a hotelier before following his real passion to Vicenza — the city known for 700 years of goldsmithing heritage, where more than 20% of all Italian jewelry is produced. He established his manufacturing operation there in 1977, initially producing for other Italian luxury lines. In 1996, he launched his own brand with the Appassionata collection, introducing the hidden ruby signature that defines every piece he has made since.
Roberto Coin’s design vocabulary is rooted in the intersection of ancient craft and modern Italian precision. His collections draw from Byzantine architecture, Baroque ornamentation, Art Nouveau botanical forms, and the bold geometric sensibility of contemporary Italian design — all executed in 18-karat gold, the metal Vicenza’s craftsmen have worked with for centuries. At Opulent Jewelers, pre-owned Roberto Coin pieces are individually authenticated before listing and backed by our full money-back guarantee.

Roberto Coin Collections
Each Roberto Coin collection has a distinct design identity rooted in a specific cultural, historical, or natural reference — all executed in 18-karat gold in Vicenza and signed with the hidden ruby.
Italian for “passion.” Interlocking ribbed gold links woven into a basket-weave pattern with fabric-like flexibility. The debut collection of 1996 and the first to carry the hidden ruby. Woven gold bracelets, necklaces, and earrings in 18-karat yellow gold.
Gold threads twisted and woven into open, textural forms inspired by Byzantine and Baroque architecture. Bold gold work with diamond accents, in yellow and two-tone 18-karat gold. Among the most recognizable Roberto Coin formats on the secondary market.
Square shapes with hand-etched and -carved detail. Geometric and graphic, combining white, rose, and yellow gold in stacking configurations. Inspired by the Classica Parisienne tradition of mixing metals into a single modern composition.
Inspired by the canals, carnival masks, and architectural ornament of Venice — Coin’s birthplace. Floral and botanical forms in 18-karat rose gold with diamond and colored stone accents. Among the most feminine and most ornate formats in the collection.
Built around Coin’s patented 100-facet diamond — a proprietary cut developed exclusively for the collection to maximize brilliance and fire beyond standard round brilliant performance. Set in 18-karat white gold in pendant, ring, and earring formats.
Effervescent bubble forms in 18-karat gold — inspired by champagne. Clusters of polished spheres in yellow, white, and rose gold, set with diamonds. Bold and joyful, among the most immediately recognizable Roberto Coin formats for its tactile three-dimensional quality.
Delicate floral forms in 18-karat rose and yellow gold with diamond pavé petals. The most wearable and most gifted Roberto Coin format — a classic flower silhouette elevated by Vicenza-level goldsmithing precision in pendant, ring, and earring formats.
Fish, horses, scorpions, octopuses, and other nature forms rendered in 18-karat gold with diamond and enamel accents. Roberto Coin’s most playful collection — each piece a complete sculptural work with the hidden ruby set inside. Highly collectible in the secondary market.
Floral and botanical motifs that pay homage to the European Art Nouveau movement — sinuous gold lines, petal and leaf forms, and the organic vocabulary of a design era that Italian goldsmithing absorbed and made its own. In 18-karat yellow and rose gold.
The Ruby You Cannot See
In 1996, Roberto Coin began setting a small ruby on the interior of every piece in the Appassionata collection — pressed against the inside surface, hidden from view, touching the skin of the person who wears it. The practice was inspired by ancient Egyptian and Burmese traditions of wearing a ruby close to the body as a talisman of love, joy, and protection. In those traditions, the stone did not need to be seen to work. Its power came from contact.
Coin translated this into a modern jewelry signature unlike anything else in the luxury market. Every Roberto Coin piece — every ring, bracelet, necklace, and earring produced since 1996 — carries this ruby. It is not decorative. It is not visible in photographs. It is a private gift from the designer to the person wearing the piece, and from the person giving the piece to the person receiving it. When authenticating pre-owned Roberto Coin jewelry at Opulent Jewelers, the presence and condition of the hidden ruby is verified on every piece before listing.
“The ruby is our signature. It is set inside each piece, close to the skin — a secret message, a gift to every woman who wears it.”
How We Authenticate Pre-Owned Roberto Coin Jewelry
Every Roberto Coin piece produced since 1996 carries a small ruby set on the interior surface. On rings, it appears on the inside of the shank. On bracelets and necklaces, it is set on the interior clasp or a link interior surface. On earrings, it appears on the back of the earring body. The presence of the ruby is the most immediate authentication marker — its absence on a piece claimed to be post-1996 Roberto Coin is a significant concern that requires further investigation.
Authentic Roberto Coin pieces carry the "ROBERTO COIN" engraving alongside the 18-karat gold hallmark ("750") on the clasp, the interior shank of rings, or a flat internal surface of the piece. The signature uses a consistent letterform and engraving depth. All Roberto Coin jewelry at Opulent Jewelers is in 18-karat gold — yellow, white, or rose. Pieces are assessed for hallmark consistency with the stated metal and collection period.
Roberto Coin’s Vicenza production is distinguished by specific construction techniques — the Appassionata basket-weave flexibility, the Byzantine Barocco wire-twist precision, the Bollicine sphere clustering — that reflect industrial goldsmithing at a level that counterfeit production cannot replicate consistently. Construction quality, clasp mechanism, and finishing are assessed on every piece against known production standards for each collection.
Diamond-set Roberto Coin pieces — Cento collection, Byzantine Barocco with diamond accents, Bollicine diamond designs — are assessed for stone security, pavé integrity, and setting precision. The Cento collection’s 100-facet diamond is verified for its distinctive cut profile. Colored stone pieces (Venetian Princess, Animale enamel designs) are examined for stone security and finish integrity. All stone and setting issues are disclosed explicitly in every listing.
The Opulent Jewelers Promise
Every pre-owned Roberto Coin piece is authenticated in-house before listing — the hidden ruby verified, house signature and 18-karat hallmark confirmed, and construction quality assessed on every piece, backed by our money-back guarantee.
Pre-Owned Roberto Coin — What Buyers Ask
Every Roberto Coin piece produced since the debut Appassionata collection in 1996 carries a small ruby set on the interior surface of the piece — pressed against the skin, invisible from the outside. The practice was inspired by ancient Egyptian and Burmese traditions of wearing a ruby close to the body as a talisman of love, joy, and protection. On rings, the ruby is set on the inside of the shank. On bracelets, it appears on an interior surface or clasp. On necklaces and earrings, it is similarly set inside the piece. The ruby does not affect the wearability of the piece. Its presence is the brand’s signature and its primary authentication marker on pre-owned pieces. Browse our pre-owned Roberto Coin collection.
Yes. Roberto Coin is a luxury Italian fine jewelry brand, founded in Vicenza — the City of Gold and the heart of the Italian gold and jewelry industry, with 700 years of goldsmithing heritage. Every piece is handcrafted in 18-karat gold in Vicenza and carries the brand’s hidden ruby signature. Roberto Coin is a member of the Responsible Jewelry Council. The brand occupies a similar market position to other Italian fine jewelry houses — genuine 18-karat gold construction, proprietary design collections, and a distinctive brand identity anchored in a single memorable signature element. Pre-owned Roberto Coin pieces are actively traded on major secondary market platforms at prices that reflect genuine secondary market demand.
The Appassionata collection — Roberto Coin’s debut collection from 1996, featuring interlocking ribbed gold links in a flexible basket-weave pattern — is the most recognized and most actively traded Roberto Coin format on the secondary market. Byzantine Barocco, with its twisted gold wire forms and diamond accents, is the second most collected format and among the most recognizable Roberto Coin designs to buyers who know the brand. The Cento collection, built around Coin’s patented 100-facet diamond, is the most significant for collectors focused on diamond quality. Princess Flower and Venetian Princess are the most widely gifted formats. Animale pieces — animal forms in 18-karat gold — are the most collectible for their sculptural character and limited secondary market availability.
The primary authentication markers are the hidden ruby, the "ROBERTO COIN" signature engraving, and the 18-karat gold hallmark ("750"). The ruby should be present on the interior surface of every piece produced after 1996 — on the inside shank of rings, on an interior surface of bracelet links or clasps, on the back of earrings. The signature and 750 hallmark appear on clasps, ring shanks, or interior flat surfaces. Construction quality is also a reliable indicator: the Appassionata basket-weave, the Byzantine Barocco wire-twist, and the Bollicine sphere clustering all have specific construction characteristics that production-quality counterfeit pieces cannot consistently replicate.
Pre-owned Roberto Coin pricing varies by collection, format, and diamond content. Appassionata bracelets and necklaces in 18-karat yellow gold without diamonds typically range from $800–$2,500. Byzantine Barocco pieces with diamond accents range from $1,500–$5,000. Princess Flower and Venetian Princess pendants and rings range from $500–$2,000. Cento collection pieces with the 100-facet diamond range from $1,200–$4,000 depending on stone size. Bollicine and Animale pieces vary widely based on configuration and stone content. All pricing at Opulent Jewelers reflects current secondary market conditions and is stated transparently in every listing.
