Glossary Of Jewellery Making & Beading Terms K To Z

Part two of a two part jewellery glossary of beading terms and jewellery making terminology. Combining clear images with easy to understand dictionary like definitions, this bead glossary also provides links to more in depth content and bead resources. It can be used as a beading A to Z reference guide to dip into as needed, or as a beading and jewellery glossary for beginners to help broaden beading and jewellery making knowledge. It is particularly effective when used alongside our Beading Guides, Histories, Theories and Tutorials, or in conjunction with our Gemstones & Minerals Glossary and Venetian Glass Making Glossary.

To allow for growth this informative beading dictionary is presented in two cross referenced sections Glossary of Beading & Jewellery Making A to J and Glossary of Beading & Jewellery Making K to Z. A jump to index is provided at the top of each bead guide to help you find information quickly. This Glossary of Beading Terms is also available as a free PDF.

Millefiori beads have plain glass cores to which thin slices of cut glass cane (known as murrine) have been applied to the surface. Each of the canes has been made up of many smaller canes arranged so that the cross-section creates a flower-like pattern. Beads can be decorated with a few murrine, or the whole surface can be covered with them. This is a technique that many polymer clay artists have borrowed from for producing their beads. Millefiori beads can only be produced by hand so the best examples can be very expensive. Occasionally these beads are also referred to as Lace Beads or Mosaic Beads.

Or Mohs Scale of Mineral Hardness, was invented in 1812 by German mineralogist Friedrich Mohs. It is a way to gauge the hardness of a gemstone or mineral when compared to other stones and minerals. The Mohs scale ranges from 1 to 10, with 1 being the softest and 10 being the hardest. Diamond, the hardest natural substance rates as a 10. However, it is worth noting that the Mohs scale does not deal with the absolute hardness of a substance, just it’s hardness as it relates to the 10 minerals Friedrich Mohs initially tested.

Pronounced oh-jay-meh are a decorative bead which originated in Japan. They are a moveable bead through which the cord of the netsuke and sagemono passes to keep an inro closed. They are typically under an inch in diameter and are often made from exquisitely carved metal, ivory, stone, jade, lacquer, tortoise shell, glass, coral, bone, antler or other natural materials.

The inro, made up of two to seven layers, was a box used for carrying small personal items such as seals, medicinal herbs, tobacco, acupuncture needles. It became fashionable alongside the traditional Kimono which had no pockets. Japanese men and women would wear this compartmentalised box hung below the obi, a wide fabric kimono belt, on a double cord. At the top of the cord, a large carved bead called a netsuke (pronounced nets-kay) acted as a toggle to anchor the inro with the cord then passing under the obi. The smaller ojime bead served as a sliding closure to secure the lid of the inro as shown below.

Bead History Ojime Beads

Their origins lie in the Edo Period (1654 to 1868) but it wasn’t until the Meiji Period (1868 to 1912) when inro became symbols of status and taste and the ojime bead evolved into a beautifully crafted object incorporating themes from everyday life as well as myths, traditions, and poetry.

The pearl is an organic gem grown within oysters and a few other molluscs. It is formed when a tiny particle makes its way into the mollusc’s shell. The irritation caused by this foreign particle forces the oyster to form a secretion, called nacre, to cover it. Nacre being the same material that forms the mollusc’s shell. When dried, the particle again irritates the animal, so it begins to secrete again. As this process continues thousands of layers of nacre coat the intruder and a pearl is formed. The process takes anywhere from four months to seven years with the length of time determining the size of the pearl. They can be found in Australia, Burma, China, Ceylon, Indonesia, Japan, Mexico, Norway, the Philippines, Scotland, Tahiti and the United States, with the finest oriental pearls are found in the Persian Gulf. “Cultured” pearls are those in which the foreign particle is implanted by man with the molluscs kept in a pearl farm while the coating process goes on.

Bead Glossary Gemstones Prehnite

Above is an example of Prehenite.


A glass bead making technique whereby heated glass rods are put into a two piece mould and the two halves brought together to create the three-dimensional shape. A needle pierces a hole in the molten bead. By making use of patterned canes (the glass rods fed into the machine) the resulting beads can be elaborately coloured, often giving the beads a slightly random appearance, even if the shape is exactly the same. One `feed’ of a hot rod might result in 10–20 beads, and a single operator can make thousands in a day. Because the bead hole is created by the introduction of a wire into the glass, rather than the bead being created around the wire (see Lampwork), it is possible to produce a bead with two or more holes. When the technique was devised in the 19th century it was the first radical change in glass bead-making for over 2,000 years! Pressed glass beads are most commonly made in the Czech Republic and Germany. Click here to read about the History of Czech Glass Beads

Also popular is a cylindrical shape, often precision made, perfect for very uniform work when producing heavily beaded items or pieces made on a bead loom.

Pure silver is very soft so most silver used for quality jewellery is 92.5% silver and 7.5% copper or other alloy. The copper allows sterling silver to be flexible and workable. All sterling silver must be 92.5% silver (or higher) and may be denoted as such with the use of the ‘925’ stamp. Occasionally you may see the phrase ‘made from sterling silver’ to describe goods that are manufactured from sterling silver, but which, due to the manufacturing process of the goods, may not test as .925 sterling silver because of the amount of manufacturing residue left on the product – this may be true of small and very intricate beads.

As distinct from Beading Wire, which is constructed to be like a metal thread, is wire in its usual form. All the common metal types are available with copper and aluminium wires coming in a rainbow of colours through the use of enamels. Wire is supplied in different Gauges (thicknesses) which are denoted by a number according to an american system or by its diameter in mm. The table below details the most common gauges and their uses for more detail see Gauges

  • 28 = 0.32mm ( 0.013”) Good for binding, knitting and weaving.
  • 24 = 0.51mm ( 0.020”) Good for threading small delicate beads. Binding and twisting.
  • 20 = 0.81mm ( 0.032”) Good for wirework with crystals and medium beads.
  • 18 = 1.02mm ( 0.040”) Good for wire wrapping large beads and creating wire components.
  • 16 = 1.02mm ( 0.040”) Good for bold chunky wire worked design.

Wire is available in four different levels of hardness: dead soft, soft wire, half-hard and full-hard. Memory Wire is the hardest of all the wire types. It also comes in a wide variety of cross-sections such as round, triangular and square and is sold both by length and weight.

  • Dead Soft Wire can be easily bent and broken with the hands, so any shape produced is vulnerable to becoming damaged or distorted. Good for wire wrapping of larger beads or stones, and thicker wire can be used.
  • Soft Wire is very similar to the above, but is slightly tougher.
  • Half Hard Wire is the most versatile type of wire as is soft enough to bend, but strong enough to act as a functional component in jewellery – i.e. for use as an earwire or eye pin. Use the correct cutters with this wire.
  • Full Hard Wire is stronger than half-hard and can be trickier to work with, again suited for use where you need reliable strength and form. Use the correct cutters with this wire.
  • Tiger Tail Wire is a speciality twisted beading wire with a nylon coating, whilst Soft Flex wire is similar but has greater flexibility and is less prone to kinking. Solid or plated silver and gold wire is also available.
