Tiffany & Co. Diamond Fleur de Lis Key Necklace

• Carat - A carat (abbreviated "ct") is a unit of measurement used to describe the weight of a diamond or other gemstone, and separately is a unit of measurement used to describe the weight of precious metals such as gold,.
  
  For gemstones, one carat is equal to 0.2 grams or 200 milligrams. The weight of a diamond is one of the Four Cs (along with cut, colour, and clarity) that are used to determine a diamond's value.
  
  It is important to note that a diamond's weight does not necessarily correspond to its size. A diamond's cut, which affects how well it reflects light, can make a diamond of a lower weight appear larger than a diamond of a higher weight. Additionally, the carat is not the only factor to determine the value of a diamond, other factors such as clarity, colour and cut are important too.
  
  In the gold industry, the purity of gold is measured in carats (abbreviated "ct"), with 24 karats being pure gold and lower carat numbers indicating a lower purity level. So, for example, 18 carat gold is 18/24 or 75% pure gold, and 12 carat gold is 12/24 or 50% pure gold.
• Openwork in Jewellery - Openwork, also known as pierced work, is a decorative technique used in jewellery making that involves removing or cutting out sections of metal from a piece of jewellery to create a pattern or design. This technique can be used in a wide range of jewellery styles, including necklaces, bracelets, earrings, and rings.
  
  Openwork jewellery can be made using a variety of different techniques, including hand carving, sawing, and laser cutting. The design can be simple or complex, and can feature a range of different shapes and motifs, from delicate floral patterns to bold geometric designs.
  
  One of the advantages of openwork jewellery is that it can add visual interest and depth to a piece without adding a lot of weight or bulk. This can be particularly appealing in larger pieces, such as necklaces and bracelets, where heavy materials can be uncomfortable to wear.
• Fleur-De-Lis - The fleur-de-lis is a stylized lily or iris flower with
  
  three petals that has been used as a decorative motif for thousands of years. It
  
  often appears in Christian iconography symbolising the Holy Trinity and as an
  
  emblem that reflects the purity of the Virgin Mary. In decorative art and antiques
  
  decoration, the fleur-de-lis is often used as a symbol of elegance, refinement,
  
  and good taste.
  
  
  
  
  The fleur-de-lis has a rich history and in ancient times, it
  
  was associated with royalty, purity, and the divine, and it was used as a
  
  symbol of the French monarchy for many centuries.
  
  
  
  
  It is a common design element in ceramics, silverware, jewellery,
  
  furniture, and other decorative objects, and it can be found in many different
  
  styles and forms.
