Knot symbol jewellery is a long-running theme in European, Mediterranean and Asian jewellery in which the visual form of a tied knot, whether a simple overhand knot, a reef or square knot, a Stafford knot, a true lover's knot, or a more elaborate decorative form such as the Carrick bend or the Celtic interlace, is used as the principal motif of a piece. The knot motif carries a recurring set of symbolic associations across the cultures that have used it: union, binding obligation, eternity, remembrance, and protection. The motif appears across two thousand years of jewellery history and remains in current use in both bridal and sentimental contexts.

Mediaeval and renaissance origins

The Stafford knot, an ornamental three-loop interlace, was adopted by the Stafford family in the late mediaeval period as a heraldic device and was carried into civic and ecclesiastical jewellery as a marker of allegiance to the family. The Bowen knot or true lover's knot, a four-loop symmetric interlace, became associated in Tudor and Stuart England with marriage and engagement and is found on numerous gimmel rings and posy rings of the sixteenth and seventeenth centuries. The Italian renaissance contributed the lacci d'amore, an elaborate ribbon-and-knot motif found in pendants and bridal girdles. Continental and English work of the period frequently combined knot motifs with set rubies, diamonds and pearls, the gems sometimes positioned to mark the crossings of the knot.

Georgian and Victorian sentimental jewellery

The knot motif found its largest market in the Georgian and Victorian periods, when sentimental jewellery as a category became one of the largest segments of the English and French trades. Lover's knot brooches, knotwork pendants, knot ear studs and knot rings were marketed for engagement, anniversary and mourning use. Mourning examples often substituted woven hair for metal, with the deceased's hair plaited into a true lover's knot and set behind a glass or rock-crystal cover within a gold or pinchbeck frame. The Victorian taste for personal symbolism gave the knot a layered set of meanings within a single piece: the form spoke of union, the use of mourning hair spoke of remembrance, and the choice of gem (jet, onyx, garnet) spoke of the relationship between the giver and the receiver.

Celtic interlace and revival

The Celtic Revival of the late nineteenth century, centred in Dublin, Edinburgh and Glasgow, brought the early-mediaeval Celtic interlace knot back into circulation in jewellery, on the model of the Book of Kells and the surviving Insular metalwork. The Penannular brooches and Tara-style pieces of the period employ knotwork as the principal decorative scheme. Continental Art Nouveau designers, including Lalique and Vever, used loose, organic knot motifs in pendants and combs. The form has remained a steady part of the trade since, with cycles of revived popularity tied to the broader oscillations of bridal taste.

Contemporary use

In contemporary fine jewellery the knot motif appears in three principal forms: the Tiffany Knot collection, which renders true lover's knots in 18-carat gold with diamond accents; the various Cartier Trinity-adjacent designs that play with the rolled-band structure of three interlinked rings, sometimes interpreted as a knot; and a continuing volume of independent designer work that revisits the Stafford and Carrick forms in handmade gold and platinum. As bridal alternatives, knot rings and knot pendants are commonly given for engagement, anniversary, and milestone events.

Care and durability

Knot-form pieces are intricate by definition and present recurring care issues. The crossings of the knot are difficult to clean and accumulate skin oils and soap residue. Hand-fabricated knots in gold and platinum are durable but susceptible to deformation if caught on clothing; cast knots reproduced from a master at scale are typically less detailed but more rigid. The symbolic and sentimental value of these pieces means that they are often kept in family collections for several generations, which makes periodic re-tightening, re-polishing and stone-checking a routine bench task on inherited examples.
