TWAIN lockup
Two stones. One bond.

An old-money fine-jewelry maison. Recognized, never advertised. This is the house book — logo, color, type, and the principles that keep it whole.

02 · Logo System

The mark

Two serif T's interlock around a single north-star — two, guided to one. Rectilinear where Cartier is curved; no vertical oval. The wax-seal is the hallmark for clasps, boxes and certificates.

FINE JEWELRY

EB Garamond carries everything you read at length — the brand story, the product copy, and the devotion line in true italic: “Wheresoever she was, there was Eden.”

Principles

Old money — recognized, never advertised

    DO
  • — Logo-quiet: the seal on the clasp, vast negative space
  • — Aged matte gold, never bright or gradient
  • — Real stone, real skin; celestial engraved into the surface
  • — Name the stone, the karat, the bench (craft as story)
  • — Design for the second wearer (heirloom)
    AVOID
  • — Gold-gradient-on-black / metallic-sheen (the #1 AI-luxe tell)
  • — Big logo on the face of a piece
  • — Saturated stones as grounds; astrology-app sparkle
  • — “Luxury / exclusive / premium / limited”; urgency
  • — Pure black #000; high-polish hardware

Corrections applied

Reviewed by a top-1% brand-director panel + an old-money skeptic. Fixes shipped: the mark was redrawn from a Cartier-adjacent oval double-C to the architectural TT; the hero quote is correctly attributed to Twain's Eve's Diary (a literary line, not written for his wife); the zodiac is framed as birth-stone provenance, not horoscope-glyph; and real product photography to spec is required before launch. Full detail in the brand book.
