1930s Emerald and Diamond Bombe Ring

• Emeralds - Emeralds have been used in jewellery making for thousands of years, and are prized for their deep green colour, which is caused by the presence of chromium and vanadium in the mineral beryl. Because of their rare colour, emeralds are often more valuable than diamonds of a similar size and quality. In jewellery making, emeralds are typically cut into round or oval shapes to maximize their color and clarity. They are often set in gold or platinum and used as the centrepiece of a piece of jewellery, such as a ring or necklace. They can also be used in combination with other gems, such as diamonds, to create intricate and beautiful designs.
• 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 "bombé" 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
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
