  • Bombe Design in Jewellery - In the early 18th century, during the reign of Louis XIV, French court jewellers developed a new style of jewellery called "bombĂ©" because of its bulging, curved shape.

    The bombe design can be found in various styles of jewellery, from Georgian, Victorian, Art nouveau, to Art Deco and Retro eras, with the materials and techniques reflecting the era the jewellery was made.

    The design is used for rings, bracelets, necklaces and earrings, where a curved or rounded shape is emphasized, giving an organic look to the piece, with the piece often made of gold and set with precious stones, such as diamonds, rubies, emeralds, and sapphires. The bombe design was also paired with other design elements such as engraving, enamelling, or gemstones
  • Onyx - Onyx is a form of agate, used from antiquity and popular again in the 1920s and 30s. European onyx is generally green, but can be many other colours, and can contain bands of black and/or white.

    This multicoloured stone is widely used for table tops, lamp bases and in jewellery. Some types of onyx are also used for cameos of which the upper white layer is cut away to reveal the colour beneath.
  • Coral - Coral used in jewellery. Coral is a material that is commonly used in jewellery making. It is made up of the skeletons of tiny marine animals called coral polyps. There are many species of coral, but only one group, Corallium, is suitable for carving, and thus can be used in jewellery manufacture. These have a deep red or pink orange skeleton and are known as "noble coral" or "precious coral".
  • Assay / Assayed - Assaying is the testing of a metal, most commonly silver and gold to determine its ingredients and quality. In Britain, once an item of silver or gold has been assayed, a mark is stamped on it, certifying its purity. Known as hallmark, it derives its name from the Guild Hall of the Goldsmiths' Company, who recieved its Charter in 1327 giving it the power to assay and mark articles of gold and silver.
