Brand Guide
Tiffany & Co.
Founded 1837 · New York
Tiffany is the most brand-recognized name in American jewelry and, paradoxically, one of the trickiest to navigate in the estate market. The brand means very different things depending on era. Pre-1960s Tiffany is exceptional — genuinely important stones, platinum craftsmanship, comparable to the great European houses. Post-2000 Tiffany is largely mass production at luxury prices. Know which you're buying. Jean Schlumberger is the dividing line. When Tiffany acquired Schlumberger in 1956, they got the most original designer working in American jewelry. His pieces — the enamel Bird on Rock, the Banana Flower, the Croisillon — are genuinely sought by museum collections. Pre-acquisition Schlumberger made pieces under his own name; post-1956 pieces are signed "Schlumberger for Tiffany." Both are desirable; the earlier studio work is rarer. Elsa Peretti is the best value play in the Tiffany universe. Her Bone cuff, Bean pendant, and Scorpion necklace are design icons that have appreciated steadily while remaining accessible. Vintage Peretti in sterling silver can be found for $500-2,000. The same forms in gold are $5,000-15,000. Neither is expensive relative to what they are — permanent parts of the design canon. Return to Tiffany heart tags are a trap for collectors. Millions were made, they come up constantly at estate sales, and novice buyers overpay for them. Condition is everything — any scratching or engraving kills value — and the supply is essentially infinite. Unless you're buying as a sentimental gift, avoid. Condition and box matter more at Tiffany than almost any other house. The brand has a large retail buyer overlap who want "as new" condition with original pouches and boxes. Estate pieces without the blue box sell at a meaningful discount to the same piece with complete packaging. Keep the box.

Signature Collections
Schlumberger
1956–1987The absolute pinnacle of American mid-century jewelry. Schlumberger's deep, saturated enamel over 18k gold is legendary. The 'Bird on a Rock' brooches are mandatory acquisitions for top-tier collectors.
Elsa Peretti
1974–presentOnly the first decade (1974-1984) matters to collectors. The early sterling silver Bone cuffs possess a heft and seamless execution that the later, lighter production runs simply cannot match.
Paloma Picasso
1980–presentHeavy, bold scale 18k gold from the greed-is-good 1980s era. The early X collection and Scribble brooches are gaining traction with specific era-focused collectors.
Tiffany Setting (Engagement Rings)
1886–presentThe iconic six-prong platinum solitaire. The real collector value here lies entirely in the 1920s-1950s examples set with Old European cuts, which are severely underpriced in the current market.
Tiffany Silver
1837–presentPre-1900 hollowware by Edward C. Moore is serious museum-grade American silver. It trades in an entirely different orbit than standard Tiffany jewelry.

What Dealers Look For
The 'T&Co' abbreviation appears on many legitimate, high-quality pieces.
Estate Tiffany pieces almost never come with original blue boxes or paperwork; the value is in the jewelry itself.
Appreciate the artistry of Schlumberger and other named designers without viewing slight hand-crafted variations with suspicion.
