The four-part composite, explained

The Hallmark is made of four marks, each a small struck figure with its own rules of construction. This page reads each in turn — the Practitioner's Mark, the Standard mark, the Accredited Assayer's cipher, and the Date Letter — and the rules by which the four are composed.

iThe Practitioner's Mark

The Practitioner's Mark is a personal cartouche: one or two serif initials reversed out of a single ink-filled figure. The figure is drawn from a closed library of six shapes. A Practitioner chooses one shape when they register, and it is theirs; the closed set keeps the marks distinct and legible down to small sizes.

Two further shapes exist but are never issued to a Practitioner: the circle is reserved for the Date Letter, and the touchstone slate for the Assayer. The six below are the whole Practitioner library. The initials shown are illustrative.

iiThe Standard mark
Standard Mark — IDEA, version III IDEA · III

The Standard mark is an oval cartouche naming the Stewarded Standard and its version — IDEA and a roman numeral. The version is part of the mark because the meaning of a Hallmark is fixed at the date it was struck: an Engagement assayed under version III carries that version permanently, whatever later versions of the standard say.

iiiThe Assayer cipher
Assayer Mark — cipher OII OII

The Assayer mark is the touchstone slate — the regime's signature figure — carrying the cipher of the Accredited Assayer that certified the work. The slate's fine gilt streak runs across the centre line. The same cipher forms the final segment of the Engagement's identifier, for example the OII in AF-2026-0001-OII, so the record itself names who certified.

ivThe Date Letter cycle

The Date Letter is a single letter set in a cartouche whose shape and case fix the cycle, while the letter fixes the year. Cycle I runs from 2026 to 2045 in a round cartouche, set in italic lower-case Cormorant. The letter j is omitted throughout, to avoid confusion with i, so the twenty years map to twenty letters. The Date Letter is derived from the date of Hallmark, never entered by hand.

Later cycles advance one shape and one style step: Cycle II (2046–2065) uses a cushion cartouche in roman capitals, Cycle III (2066–2085) an arch-top cartouche in small capitals. Shape and case together fix the cycle; the letter fixes the year.

vHow the four are composed
  1. 1

    Fixed sequence. Practitioner, Standard, Assayer, Date Letter, struck left to right, always and in that order.

  2. 2

    A single gilt midline dot separates each mark from the next — never a slash, a comma, or a space alone.

  3. 3

    The marks are optically centred on their visual centre, not on the bounding box, so that figures of different heights sit on one line.

  4. 4

    Minimum height sixteen pixels on screen. Below it the initials may drop, but the cartouche shapes never do.
