• Alexandrite - Alexandrite is a variety of the mineral chrysoberyl that is prized for its unique ability to appear to change colour under different lighting conditions. It is a highly sought-after gemstone and is often used in fine jewellery. In natural light, alexandrite appears to be a shade of green, but when viewed under incandescent light, it appears to be a shade of red. This property, known as the alexandrite effect, is caused by the presence of trace amounts of chromium in the crystal structure of the gemstone. The colour change is due to the way that the gemstone absorbs and reflects light. Alexandrite is a relatively hard gemstone and is suitable for use in all types of jewellery, including rings, earrings, pendants, and bracelets. It is often used as a centre stone in engagement rings, due to its rarity and beauty. It is also used in other types of fine jewellery, such as brooches, necklaces, and cufflinks. The gemstone is typically cut into oval, pear, or cushion shapes and is usually set in gold or platinum.
• 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
