"Founded in Geneva in 1886, Adler has spent nearly 140 years creating heirloom-quality jewelry that balances European heritage with modern sensibility — a rare combination that defines true luxury."
About Adler Jewelry
Founded in Geneva, Switzerland in 1886, Adler is one of Europe's most respected fine jewelry houses — a family-run maison now in its fourth generation of master craftsmen. For nearly 140 years, Adler has created exceptional jewelry and watches from its Geneva atelier, combining the precision and perfectionism of Swiss tradition with a deeply personal approach to design. Each Adler piece is conceived, crafted, and finished by hand — a commitment to artisanal excellence that is increasingly rare in the modern luxury landscape.
Adler has long been a jeweler of choice among European royalty, collectors, and discerning clients worldwide. The house is known for its extraordinary use of colored gemstones — rubies, sapphires, emeralds, and rare fancy-colored diamonds — set alongside brilliant-cut and fancy-cut diamonds in 18K yellow, white, and rose gold. At Opulent Jewelers, our pre-owned Adler collection offers authenticated pieces from this celebrated house at prices well below retail, backed by our full money-back authenticity guarantee and free domestic shipping.
The Adler Collections
The Vintage Collection
Adler's Vintage collection draws on the great jewelry traditions of the late 19th and early 20th centuries — incorporating intricate filigree work, delicate hand engraving, and ornate milgrain detailing. These pieces celebrate the elegance of a bygone era while meeting the highest contemporary standards of craftsmanship. For collectors who appreciate historical jewelry aesthetics rendered in exceptional modern materials, the Vintage collection is an extraordinary choice.
The Classic Collection
The Classic collection reflects Adler's belief that true luxury is defined by restraint. Clean architectural lines, minimalist silhouettes, and flawless finishing characterize these enduring designs — rings, necklaces, bracelets, and earrings conceived to be worn across decades without ever looking dated. These are the pieces that become heirlooms.
The Rosaria Collection
Inspired by the rose in full bloom, the Rosaria collection is Adler at its most romantic. Intricate floral motifs, pavé-set diamond petals, and softly curved gold work combine to create pieces of extraordinary femininity and beauty. The Rosaria collection is among Adler's most sought-after on the secondary market — particularly for engagements, anniversaries, and landmark occasions.
The Men's Collection
Adler's Men's collection brings the same standard of Swiss craftsmanship to accessories for the modern gentleman — cufflinks, tie clips, and money clips crafted in 18K gold with diamond and gemstone accents. Understated, refined, and built to last, these pieces are the definition of quiet luxury for men who understand the difference.
Materials & Craftsmanship
Every Adler piece begins with an uncompromising selection of materials. The house works exclusively in 18K yellow, white, and rose gold — chosen for its richness, durability, and ability to showcase the full brilliance of set stones. Diamonds are individually selected for cut, color, clarity, and carat weight, ranging from perfectly matched brilliant-cut stones to rare fancy-colored diamonds of exceptional provenance.
Beyond diamonds, Adler's signature use of colored gemstones sets the house apart. Burmese rubies, Ceylon sapphires, Colombian emeralds, and natural pearls are sourced from the world's finest suppliers and evaluated against strict internal standards before they are approved for use. The result is jewelry of extraordinary chromatic richness — pieces where color, light, and form work in perfect concert.
Adler's Geneva craftsmen work entirely by hand, from the initial wax model through to final polishing. Each piece passes through multiple stages of quality control before leaving the atelier — ensuring that every Adler jewel meets the house's 140-year standard of excellence.
Every Adler piece at Opulent Jewelers is individually authenticated and carefully sourced from our network of trusted collectors. Each piece is verified for hallmarks, craftsmanship, and condition before listing — offered with our full money-back authenticity guarantee and free domestic shipping.
