Lapponia Sterling Silver Sirene Ring, 1971

• Sterling Silver - Sterling silver is a mixture of 92.5% pure silver and 7.5% of another metal, usually copper. Fine silver is 99.9% pure silver, and is relatively soft and the addition of the very small amount of copper gives the metal enough strength and hardness to be worked into jewellery, decorative and household objects.
• Modernism / Modernist - Modernist furniture and design emerged in the early to mid-20th century as a response to traditional styles of the 19th century and prior times, and a reflection of the technological and social changes of the time. Characteristics of Modernist furniture and design include simplicity and minimalism and clean lines and a lack of unnecessary ornamentation are key features. That form follows function is a fundamental principle of Modernist design, and furniture and objects are designed with a focus on their practical use.
  
  Modernist furniture often incorporates geometric shapes, such as cubes, rectangles, and circles. This reflects a departure from the more ornate and curvilinear forms of previous design styles. The furniture often prioritizes ergonomic design, ensuring that objects are comfortable and user-friendly. Modernist designers aimed to create designs that could be mass-produced, making good design accessible to a broader population.
  
  Prominent figures associated with Modernist furniture and object design include designers such as Hans Wegner, Verner Panton, Florence Knoll, Harry Bertoia and Ettore Sottsass
• 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.
