However, doubts have been expressed whether the painting titled John Cuff actually is a portrayal of him, and it has also been known as The Lapidaries or Two Old Men.

Lapidary medicine is a pseudoscientific concept based on the belief that gemstones have healing properties. The source of the idea of lapidary medicine stems from information found in lapidaries, books giving "information about the properties and virtues of precious and semi-precious stones." These lapidaries not only provide understanding of the sale and production of items of lapidary medicine, but also provide information about common cultural practices and beliefs about gemstones. The most common application of the concept was to embed precious stones within open-backed jewelry.

The lapidary products were used as status symbols, for offerings, and during burials. They were made from shell, jade, turquoise, and greenstones. Aztec lapidaries used string saws and drills made of reed and bone as their lapidary tools.

The ring probably functioned as a love token or betrothal ring. Medieval lapidaries suggest that emeralds were associated with chastity and rubies with love and prevention of anger, which may have been important qualities in a medieval relationship.

Oil of brick was used in pre-modern medicine as a treatment for tumors, in the spleen, in palsies, and epilepsies. It was used by lapidaries as a vehicle for the emery by which stones and gems were sawn or cut.

Beading, or beadwork, is also very popular in many African and indigenous North American cultures. Silversmiths, goldsmiths, and lapidaries use methods including forging, casting, soldering or welding, cutting, carving and "cold- joining" (using adhesives, staples and rivets to assemble parts).McCreight, Tim. Jewelry: Fundamentals of Metalsmithing.

He also recognises that other minerals have characteristic crystal shapes, but in one example, confuses the crystal habit with the work of lapidaries. He was also the first to recognise that amber was a fossilized resin from pine trees because he had seen samples with trapped insects within them.

Metalsmiths, beaders, carvers, and lapidaries combine a variety of metals, hardwoods, precious and semi-precious gemstones, beadwork, quillwork, teeth, bones, hide, vegetal fibres, and other materials to create jewellery. Contemporary Native American jewellery ranges from hand-quarried and processed stones and shells to computer-fabricated steel and titanium jewellery.

Title page of a printed lapidary by Conrad Gessner of 1565 A lapidary is a text, often a whole book, giving "information about the properties and virtues of precious and semi-precious stones", that is to say a work on gemology.Glick et al, 306; Vauchez, 821 Lapidaries were very popular in the Middle Ages, when belief in the inherent power of gems for various purposes was widely held, and among the wealthy collecting jewels was often an obsession, as well as a popular way to store and transport capital.Wheaton The medieval world had little systematic geological knowledge, and found it difficult to distinguish between many stones with similar colours, or the same stone found in a variety of colours.Harris, 15–17 Lapidaries are often found in conjunction with herbals, and as part of larger encyclopedic works.

Examples of lapidary products A rural Thai gem cutter (1988 photograph) A lapidary (lapidarist, ) is an artist or artisan who forms stone, minerals, or gemstones into decorative items such as cabochons, engraved gems (including cameos), and faceted designs. A lapidarist uses the lapidary techniques of cutting, grinding, and polishing. Hardstone carving requires specialized carving techniques. Diamond cutters are generally not referred to as lapidaries, due to the specialized techniques which are required to work diamonds.

Jadeite rates between 6 and 7 on the Mohs scale of hardness, therefore making it extremely tough and time-consuming to work because it was necessary to use minerals of equal or harder value. Abrasive powders made of these minerals were often used to carve into the material. Some of the main techniques used were pecking, drilling, sawing, carving, engraving and grinding. String sawing was a technique likely developed by Costa Rican lapidaries, in the northeastern region.

Dunlop's work is characterised by the use of semi-precious and precious gems, such as chalcedony, chrysoprase, moonstone, amethyst, agate, quartz and opals, often cabochon rather than facet-cut gemstones, set in silver in symmetrical patterns, often inspired by nature. One of her most famous designs is the 'Carpet of Gems' symmetrical setting. The gemstones were cut for Dunlop by lapidaries in Germany. Dunlop's work is often confused with that of another female jewellery designer of the same period, Dorrie Nossiter.

Abbreviated writing, using sigla, arose partly from the limitations of the workable nature of the materials (stone, metal, parchment, etc.) employed in record-making and partly from their availability. Thus, lapidaries, engravers, and copyists made the most of the available writing space. Scribal abbreviations were infrequent when writing materials were plentiful, but by the 3rd and 4th centuries AD, writing materials were scarce and costly. During the Roman Republic, several abbreviations, known as sigla (plural of siglum = symbol or abbreviation), were in common use in inscriptions, and they increased in number during the Roman Empire.

Archaeological Museum of Lothal, replica of seal. Pieces of red clay pottery The discovery of etched carnelian beads and non-etched barrel beads in Kish and Ur (modern Iraq), Jalalabad (Afghanistan) and Susa (Iran) attest to the popularity of the Indus bead industry across West Asia. The lapidaries select stones of variegated colours, producing beads of different shapes and sizes. The methods of Lothal bead-makers were so advanced that no improvements have been noted over 4,000 years—modern makers in the Khambhat area follow the same technique.

Zuni jewelry-making dates back to Ancestral Pueblo prehistory. Early Zuni lapidaries used stone and antler tools, wooden drills with flake stone, or cactus spine drillbits, as well as abrading tools made of wood and stone, sand for smoothing, and fiber cords for stringing.Slaney, Deborah C. "The Evolution of Zuni Jewelry." Southwest Art. 1 August 1998 (retrieved 4 August 2011) With the exception of silver jewelry, which was introduced to Zuni Pueblo in the 19th century, most of the materials commonly worked by Zuni jewelry makers in the 20th century have always been in use in the Zuni region.

German naturalist Johann Walch, who executed the first inclusive study of this group, proposed the use of the name "trilobite". He considered it appropriate to derive the name from the unique three-lobed character of the central axis and a pleural zone to each side. Written descriptions of trilobites date possibly from the third century BC and definitely from the fourth century AD. The Spanish geologists Eladio Liñán and Rodolfo Gozalo argue that some of the fossils described in Greek and Latin lapidaries as scorpion stone, beetle stone, and ant stone, refer to trilobite fossils. Less ambiguous references to trilobite fossils can be found in Chinese sources.

A school of lapidaries expounded the symbolism of gems mentioned in the Bible, especially two sets of precious and semi-precious stones listed there. The first of these were the twelve jewels, in engraved gem form, on the Priestly breastplate described in the Book of Exodus (), and the second the twelve stones mentioned in the Book of Revelation as forming the foundation stones of the New Jerusalem ()—eight of these are the same (or were in the Vulgate translation). The late Anglo- Saxon Old English Lapidary took the latter group as its subject. The symbolism of these sets had been explored by theologians since Saints Jerome and Augustine.

Large stones were greatly valued, and many rulers and great nobles amassed collections, which were often frequently reset. Lapidaries or books listing different gems, were an extremely popular type of work in the Middle Ages, and listed the many medical and quasi-magical powers attributed to gems, as well as their religious symbolism and sometimes their astrological significance.Sapphires were also attributed with magical powers and had certain properties that were used to detect fraud, cure snakebites, and expel witchcraft. Ancient engraved gems were often reused among stones, which in early medieval jewelled objects were often set profusely, spaced out across surfaces, mixed with ornaments in gold.

The mission station became a staging post for expeditions to the interior - here David Livingstone met his future wife, Mary Moffat, daughter of the missionary Robert Moffat - William Burchell visited here in 1811. John Campbell described the mountains in his book "Travels in South Africa: Undertaken at the request of the Missionary Society": The coloured variants, which Campbell found, are named because of their chatoyance: tiger's eye, hawk's eye, and cat's eye by lapidaries, and are silicified crocidolite. Wonderwerk Cave is located in the range near Kuruman and was occupied by man during the Later Stone Age, while much earlier manuports, introduced by hominins in the terminal Acheulean, have been found at the back of the cave.

Both concentrated on the appearance of a wide range of minerals, where they came from, and how they were extracted and used.Harris, 45–50 While Pliny and others wrote on how to detect fake or imitation gems, some, like Jean d'Outremeuse (d. 1400), described how to make them in coloured glass, which by the Late Middle Ages was recommended for use in church metalwork.Vauchez, 822; Harris, 17 Most classical lapidaries are lost; of the 38 works listed by Pliny (in Book XXXVII), only Theophrastus' text survives.Harris, 55 There are hundreds of different medieval texts, but most are mainly based on a number of large works which were redacted, translated and adapted in various ways to suit the needs of the individual manuscript.

Cut emeralds In his treatise On Stones (Περὶ λίθων), which was to be used as a source for other lapidaries until at least the Renaissance, Theophrastus classified rocks and gems based on their behavior when heated, further grouping minerals by common properties, such as amber and magnetite, which both have the power of attraction.... He also comments on the different hardnesses of minerals. Theophrastus describes different marbles; mentions coal, which he says is used for heating by metal-workers; describes the various metal ores; and knew that pumice-stones had a volcanic origin. He also deals with precious stones, emeralds, amethysts, onyx, jasper, etc., and describes a variety of "sapphire" that was blue with veins of gold, and thus was presumably lapis-lazuli.

Just as drugs derived from plants were and are important in medicine, it seemed natural to the ancient and medieval mind that minerals also had medical properties (and indeed many mineral-derived chemicals are still in medical use). Saint Thomas Aquinas, the dominant theologian of the Late Middle Ages, propounded the view that the whole of the natural world had ultimately been created by God for the benefit of man, leading medieval Christians to expect to find beneficial uses for all materials.Harris, 1–2, 41–42, 45 Lapidaries listed the medical benefits of particular gems, with "the most common method of medical application" being wearing the stone on one's person in a jewellery setting, for example in a ring. Open-backed settings allowing direct contact between the skin and stone were encouraged; otherwise the stone might simply be held against the skin.Harris, 8–9, 8 quoted Other forms of application included ointments containing ground stones or taking the stone internally in ground form, often as part of a cocktail of several different herbal, mineral and other ingredients; this seems to have become especially often mentioned in the 16th and 17th centuries.
