Artefacts made of jet and of similar-looking but geologically distinct materials, principally cannel coal and shale, are known from Neolithic contexts in Scotland and elsewhere in Britain – including on Skye – but they are rare (Sheridan and Davis 2002; Sheridan 2012d). Similarly, a few objects made from these materials are known from Chalcolithic contexts in Britain, but a marked upswing in the manufacture of jet and jet-like jewellery and dress accessories occurred during the 22nd century BC (Sheridan and Davis 2002). It was during this time that the rich deposits of jet around Whitby, North Yorkshire, were exploited by specialist craft workers who produced a range of products, including necklaces and buttons. Virtually all of these have been found in funerary contexts. These items were clearly used as status symbols, being rare and precious, and they may also have been used as amulets. These items may have been attributed special powers on account of the unusual qualities of jet: it is warm to the touch, can float, can burn and is electrostatic. The term ‘supernatural power dressing’ has been coined to express this amuletic use of jet artefacts (Sheridan and Shortland 2003). Whitby jet continued to be exploited, at varying intensities, during and after the Bronze Age, as did substitute materials such as cannel coal and oil shale, which are more widely available including in the Highland Region.
Jewellery and dress accessories of jet and jet-like materials in Britain have been studied over the last 30 years by Sheridan and Davis, along with other colleagues at National Museums Scotland (Davis 1990; Sheridan and Davis 2002; Davis et al 2015; Sheridan 2000; 2015b; 2017b; 2021b). Several of the extant examples from the Highland Region have been included in this National Museums Scotland project, such as the Lairg finds (Sheridan et al 1998); the final results of the project will be published in a corpus. Some of the analytical results are published for the first time here. Note that Davis’s (1990) thesis for her Diploma of Conservation, University of Durham, analysed inter alia the spacer-plate necklaces from Achcheargary Burn (MHG11079) and Torr Sgriobhaidh (MHG41004) as well as various artefacts from Culbin Sands. The research has included compositional analysis, mainly using X-ray fluorescence spectrometry, to determine and, where possible, source the raw materials. It has also examined the processes of manufacture (Sheridan 2017b), patterns of use and individual biographies of the objects in question. The project has not only confirmed that not all black objects are jet (as noted in the ScARF Bronze Age section 126.96.36.199) but also revealed trends and patterns in the use of different materials. For example, locally-available substitutes for Whitby jet would be used to make replacement beads in spacer-plate necklaces as individual beads broke. Pieces of old spacer-plate necklaces would be ‘recycled’ and sometimes re-shaped for incorporation into another necklace, as is the case with the spacer-plate necklaces from Achcheargary Burn, Strathnaver, Sutherland (aka Dalmor, MHG11079), and from near the Old House of Assynt (MHG8968).There, parts of old, worn spacer plates had been cut down and re-used as beads. The Achcheargary Burn necklace also contains several beads made of cannel coal, which could have been obtained within the Highland Region.

This map is based on the information in Table 6.9
The range of jet and jet-like artefacts in use between 2200 BC and 1800 BC, the first four centuries of the Early Bronze Age, in the Highland Region comprises the following, with the possibility that one or two of the disc-bead necklaces could possibly be of Chalcolithic date (pre-2200 BC):
- Disc-bead necklaces (Sheridan and Davis 2002)
- Isolated disc beads (ie finds of fewer than five beads)
- A disc- and fusiform-bead necklace (at Embo: MHG11630; see Table 6.9 for references)
- A unique disc- and fusiform-bead belt (at Culduthel: MHG3782; Parker Pearson et al 2019, fig 4.28)
- Spacer-plate necklaces (Sheridan and Davis 2002)
- Isolated fusiform beads (ie finds of fewer than five beads)
- V-perforated buttons (Shepherd 2009)
These examples are listed in Table 6.9. An additional object that is likely to be of Early Bronze Age date is a lost ‘thin circular piece of shale, around 2 inches [50.8 mm] in diameter, apparently an ornament’ from a possible log coffin at Stittenham, Dalnavie (MHG8159; Maclean 1886, 333). Three barbed and tanged arrowheads were associated with the object. The description of this object does not match that of any known type of Early Bronze Age artefact, however.
The necklaces are all incomplete; they may well have been incomplete when buried, but in many cases the conditions of discovery were such that individual beads may well have been missed. The origins and development of the various artefact types have already been discussed in print elsewhere (Sheridan 2015a; Shepherd 2009). Essentially, the use of disc beads and of V-perforated buttons are among the continental innovations introduced by immigrant Beaker people, or these innovations were adopted through subsequent contacts with such people on the Continent. The use of both artefact types continued for several centuries, as is clear from the date of the Culduthel belt with its tiny disc beads (MHG3782; Case Study Culduthel Iron Age Settlement). Note that the necklace with tiny disc-beads from Yarhouse, Caithness (MHG2229), could be of Chalcolithic date as it was associated with what appears to be an All-Over-Cord-decorated Beaker.
The design of disc-bead necklaces evolved into a version featuring larger, graded-size disc beads, as exemplified by the examples from Lairg, Sutherland, and Dalmore, Easter Ross (MHG6311). Only 12 disc beads plus a discoidal bead or fastener were found at Lairg. This means that we cannot be certain that this was not a bracelet; well-preserved examples from elsewhere all appear to have been necklaces, so it is assumed that they belonged to a necklace. The interment of small numbers of beads that probably originated in a disc-bead necklace is attested at Morayston (MHG2908). That disc beads from such necklaces could be ‘recycled’ for re-use in other artefacts is clear from the six non-tiny disc beads found in the Culduthel belt and from the disc beads in the disc- and fusiform-bead necklace from Embo. The belt that was found in the waist area of an adult female at Culduthel is unique, although, more generally, the presence of belts in male graves around the same time is attested elsewhere in Britain. At Culduthel, the tiny disc beads are of an unusual material, possibly lignitic; further research is needed to determine the source of the material (Hatherley & Murray 2021).
Of particular interest is the unfinished disc-bead necklace found in a cist at Dunrobin Park, where only six of 118 beads were perforated (MHG10900). This find suggests that there was a desire to bury a prestigious artefact with the deceased, but a complete one was unable to be acquired. So an attempt was made to make one, or a simulacrum of one, almost certainly using locally available material (probably shale).
Spacer-plate necklaces were – despite claims to the contrary – skeuomorphs of gold lunulae, and the decorated examples shared designs with lunulae. In the past they have been reconstructed wrongly, with fusiform beads arranged in a criss-cross pattern, but detailed examination has shown that they had been strung as continuous strands, increasing in length from the inner to the outer strand and thereby creating the impression of a solid area of black, analogous to the solidity of a lunula (Sheridan 2017b). The examples from the Highland Region are all incomplete and, as noted above, some components from examples discovered long ago may have been lost. However, it is clear that some include parts ‘recycled’ from other necklaces, attesting to the long use-life of some of these necklaces. In addition to the example cited above from Achcheargary Burn, the Torrish necklace incorporated spacer plates from an old necklace with both undecorated plates and decorated plates. Similarly, individual beads from spacer-plate necklaces could be buried on their own, as at Lierabol (MHG9513) and Cladh Aindreis (MHG459), or incorporated into other artefacts, as with the belt from Culduthel and the disc-and-fusiform bead necklace from Embo.
Of note is the find from near the Old House of Assynt, where parts of a complete Parure of spacer-plate jewellery was found, comprising part of a spacer-plate necklace and parts of a pair of spacer-plate bracelets. Such sets, often with just a single bracelet, and in the case of Melfort, Argyll and Bute, and Masterton, Fife, with bronze bangles taking the place of jet spacer-plate bracelets, are paralleled elsewhere in Early Bronze Age Scotland (Clarke et al 1985, 286, 288–9, figs 4.38, 5.14, 5.48, 5.50; note that the Masterton necklace has no plates).
Only a few V-perforated buttons have been found in the Highland Region; they were reviewed by the late Ian Shepherd (2009). Shepherd includes the boat-shaped V-perforated fastener of jet from the Culduthel belt in his corpus and the round, domed button used, or reused, as a fastener for the Achcheargary Burn spacer-plate necklace and the set of six cannel coal buttons found in the Migdale hoard (MHG10007; Case Study: The Migdale Hoard).
The sex associations of the various artefacts are as follows: where the sex of the associated human remains can reliably be established, it is mostly female. The set of six V-perforated buttons in the Migdale hoard could well have belonged to a male jacket, or else five of the buttons could be used in this way, with the larger sixth one used to fasten a cloak, since such button sets have been associated elsewhere with male burials, as at Rameldry Farm, Fife (Baker et al 2003). A very few associations of disc-bead necklaces with males have been recorded in Britain (as discussed in Sheridan 2015a). Among the sexed individuals associated with jet and jet-like objects in the Highland Region, the sex has been female, as shown in Table 6.9.
The raw materials used for these Early Bronze Age artefacts range from Whitby jet to cannel coal, (oil) shale and possibly lignite. Cannel coal and shale outcrops can be found in Sutherland, particularly in the Jurassic deposits around Brora. Albertite, which outcrops at Strathpeffer, Easter Ross, may have been used to manufacture one or more of the Early Bronze Age beads found on Culbin Sands. Disc beads tend not to be made of jet, with but a few exceptions elsewhere in Britain (Sheridan 2015a), not least because they are easier to manufacture using laminar materials such as cannel coal and shale. With the V-perforated items, the Culduthel and Achcheargary Burn examples are of Whitby jet, while the button set from Migdale is of cannel coal or shale. The identifications and claimed identifications are presented in Table 6.9. Further research needs to be undertaken on identifying the source of the possibly lignitic material used to make the tiny disc beads in the Culduthel belt.
The use of jet declined after c 1800 BC in the Highland Region, possibly due to changes in the pattern of interregional contacts. The Middle Bronze Age use of jet-like material, including the manufacture of artefacts, is attested at the settlement at Lairg, where one bangle fragment of shale was found in a context dating to 1200–1000 BC. Other bangle fragments from Iron Age contexts were also found. A roughout of albertite, possibly for a bead, was found in a context dating to about 1500–1300 BC, and a roughout for a discoid bead or ring of cannel coal was found in a similarly-dated context. Other working debris in the form of a flake from a context dating to 1600–1400 BC were also found. The presence of the bangle fragment in a Middle Bronze Age context provides welcome confirmation that this artefact type was indeed being made at that period. The earliest evidence for the use of bangles made of jet-like material in Scotland comes from Bodsberry Hill, Elvanfoot, South Lanarkshire, where fragments were found in a context dated to the Early Bronze Age (Sheridan et al 1998).
There is only one other piece of evidence for the Middle Bronze Age use of jet-like materials: the toggle-like object of cannel coal found in a roundhouse at Rhiconich, Sutherland (MHG12143). This had been made by cutting down an annular object, possibly a bangle, and it may relate to the Middle Bronze Age period of occupation.
As with the Middle Bronze Age, just one Late Bronze Age artefact can be cited for the Highland Region: a bead with a slightly wedge-shaped profile, found at Cantraybruich and identified analytically as being of cannel coal (MHG61783; Sheridan 2000). This is the kind of bead that is found in some Late Bronze Age composite necklaces of amber and black material, such as the example from Balmashanner, Angus.
Table 6.9 summarises the confirmed examples of Bronze Age and possibly Chalcolithic finds of jet and jet-like artefacts in the Highland Region, including finds from Culbin Sands, since the Sands straddle the Highland and Moray boundary. Excluded from this table are finds where the Bronze Age date cannot be confirmed but could be at a later date; these comprise two beads from Littleferry Links (MHG11651; NMS X.BJ 2307–8); two abandoned roughouts for albertite beads found during topsoil stripping at Slackbuie, Inverness (EHG3271; Sheridan 2012a); and several beads from Culbin Sands in Nairn Museum and Dunrobin Castle Museum. The Iron Age finds from Lairg settlement are also excluded.
