What Is Milgrain?

Milgrain (also spelt millegrain or millgrain) is a fine decorative edging in which a small wheel presses a continuous line of tiny beads along the edge of a metal setting or mount, giving a delicate, textured border.

What Milgrain Is Structurally

Milgrain is applied with a hand tool called a milgrain wheel or milgrain tool: a short handle holding a tiny hardened-steel wheel whose rim is cut with a row of small cup-shaped hollows. The jeweller runs the wheel firmly back and forth along a thin, raised edge of metal - the top of a collet, the rim of a ring shank or the edge of a gallery. As it turns, each hollow presses the metal into a small rounded bead, so that the edge becomes a continuous row of beads. No metal is removed, as it would be in engraving; the metal is reshaped. Wheels were made in a range of numbered sizes, so that the beads could be matched to the scale of the piece.

The name comes from the French mille grains, “a thousand grains”. A related French term, millegriffe (“a thousand claws”), is used for a setting in which a stone is held by a collet edge worked into many tiny beads or claws; in English the two terms are often used loosely for the same effect.

What It Does

Milgrain has practical as well as decorative uses:

• It breaks up a plain metal edge into points of light, which makes the outline of a setting look finer.
• Around a stone, the beaded rim reflects light and can make a small diamond appear slightly larger.
• It disguises minor irregularities where the edge of a collet has been pushed over the stone.

Before milgrain wheels came into general use, goldsmiths raised individual beads along an edge with a graver and rounded them with a beading tool - the same method used in pavé setting. Hand-raised beading of this kind appears on 18th- and 19th-century work, and the wheel made the effect quicker and more regular.

Typical Applications

Milgrain edging was used on the edges of fine claw and collet settings, along the rims of bands and the edges of galleries and openwork mounts. It suited fine platinum work, where the metal’s strength allowed settings to be made very thin without losing durability, and milgrain’s fine detail complemented the lace-like openwork fashionable after 1900.

Edwardian and Art Deco Platinum Jewellery

Milgrain is especially associated with Edwardian platinum jewellery of about 1900-1914. In the garland style practised by Cartier, Boucheron, Chaumet and leading London jewellers, almost every collet, knife-edge bar and openwork scroll was finished with milgrain, giving the whole jewel a soft, glittering outline that echoed the lace and embroidery of fashionable dress. It appears on tiaras, corsage ornaments, bow brooches, lavalier pendants, bar brooches and cluster rings, often with pavé-set diamonds.

Milgrain continued into Art Deco jewellery of the 1920s and 1930s, though bolder geometric designs gave it a less dominant role. It was particularly common on American engagement rings of the 1910s-1930s in platinum and white gold, many of them with pierced or die-struck openwork mounts and milgrain on every edge. Milgrain wedding bands in platinum and white gold were also popular in the same decades.

Milgrain as a Period Indicator

Original milgrain on a platinum mount with other Edwardian or Art Deco features is consistent with a date between about 1900 and 1940. On its own, however, it is suggestive rather than conclusive: milgrain continued to be used after the Second World War, and reproductions and modern pieces in “vintage” style use it widely. It is also easy to add to an older piece during repair or remodelling. Milgrain alone, without other supporting features of construction, metal and setting style, is not a reliable means of dating a piece.

How to Recognise It

Look for a fine, continuous row of small, evenly spaced rounded beads running along an edge, seam or border, distinct from a plain smooth edge or from coarser, less regular beading raised by hand. Even, regular spacing generally indicates a milgrain wheel; irregular or widely spaced beading may indicate hand work, a hand-applied repair, or a worn example. On modern cast jewellery the milgrain is often cast in as part of the model, which tends to give softer, less crisp beads than wheel-worked milgrain.

Frequently Asked Questions

Is milgrain only found on platinum jewellery? No - while most strongly associated with Edwardian and Art Deco platinum work, milgrain was also applied to gold and other metals across various periods, including modern reproductions, so it should not be used on its own to date a piece.

Does worn or flattened milgrain indicate an older piece? Not reliably - flattening can result from age and handling, but also from poor original execution or from wear on a more recently made piece.
