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.
