Onyx grief is the name modern lapidary writers sometimes give to a cluster of beliefs from classical antiquity that attributed sorrow, melancholy, and disturbing dreams to the wearing or possession of onyx. The most widely cited source is Pliny the Elder's Natural History (Naturalis Historia), completed around 77 CE, which records — in its survey of stones — the contemporary belief that onyx provoked sadness and quarrelling. The superstition is curious for sitting alongside the same period's vigorous practical use of onyx for cameos, intaglios, and signet rings, suggesting that classical authors held the belief loosely and that the stone's commercial appeal was not significantly impaired by it.

The classical sources

Pliny's account of onyx (Book 37 of the Natural History) describes the stone's banded character, its sources, and the contemporary trade in it, before noting that some authorities held it to provoke disquiet in the sleeper. He does not endorse the view; his presentation is in the cataloguing manner that characterises the work. Other classical sources — Theophrastus's On Stones, Solinus's Polyhistor, and the later medieval lapidaries that drew on these classical texts — repeat or vary the same association, and the belief is therefore best understood as a stable element of the late-antique lapidary tradition rather than a personal opinion of any single author.

Medieval Christian lapidaries — the best known being the Marbode of Rennes lapidary of the eleventh century — incorporated and elaborated the classical attribution, sometimes adding a moral dimension and sometimes proposing remedies, including the wearing of sard alongside onyx to neutralise its effect. The tradition therefore reaches the high Middle Ages substantially intact, before fragmenting in the Renaissance lapidary literature.

Why onyx?

The likely cultural source of the association is the colour. Black and dark banding had strong symbolic links with mourning, the night, and the underworld in Mediterranean cultures, and onyx — particularly in its black or dark-banded forms — was the principal stone in that colour register. Jet, which is altogether more fragile and less suitable for fine carving, played a similar role in northern European mourning traditions. The sympathetic-magic logic that aligned colour with emotional state was a stable feature of classical and medieval natural philosophy, and the attribution of sadness to a black stone is consistent with the broader pattern.

An alternative explanation is etymological. The Greek onyx means fingernail, with associations to the body's extremities and to the dead — fingernails continued to grow, in popular belief, after death. The connection between the stone's name and the body's residue may have contributed to the association, although the etymological link is a modern speculation rather than a position held by the ancient sources.

The coexistence of belief and use

What makes the onyx grief tradition particularly interesting is that it ran in parallel with onyx's central role in classical glyptic art. Roman cameo cutters were producing major dynastic and mythological cameos in onyx and sardonyx throughout the same centuries in which the lapidary literature recorded onyx as a sorrowful stone. The Gemma Augustea, the Great Cameo of France, the Cup of the Ptolemies — none of these would have been commissioned in onyx if the imperial households had taken the superstition seriously. The most reasonable conclusion is that the lapidary attribution functioned as a piece of antiquarian learning rather than a practical taboo, and that the working trade in onyx proceeded on its own terms.

The pattern recurs across gem folklore: stones that lapidaries treated with caution often saw vigorous practical use in jewellery and ornament, and the gap between the literary tradition and the workshop tradition is one of the features that makes lapidary history a distinctive subject within the broader history of material culture.

Modern reception

The onyx grief attribution survives in lapidary handbooks of the nineteenth century, particularly those compiled in Britain and France during the romantic and gothic-revival periods, when classical superstitions were collected with antiquarian enthusiasm. Modern gemmology recognises no physical mechanism by which any gemstone could produce psychological effects in a wearer, and the superstition is now of historical and folkloric rather than practical interest. It survives in occasional references in metaphysical or new-age gemstone literature, often quoted alongside contradicting attributions of protection or strengthening, which themselves appear in other branches of the same tradition.

The persistence of the literature reflects the more general pattern of gemstone folklore: stones accumulate symbolic associations across centuries, the associations contradict one another, and the resulting body of attribution is a record of cultural anxieties and hopes rather than a stable system of belief.

In the trade

Onyx today is sold without folkloric weight in any meaningful proportion of the trade. Customers occasionally ask about historical associations, and the onyx grief tradition is part of the answer for those interested in the cultural history of the stone. For working jewellers, the tradition is best presented as the historical curiosity it is, alongside the much larger record of onyx's continuous use in cameo, intaglio, mourning jewellery, dress watch dials, and decorative work from antiquity to the present.
