Emerald and Diamond Antique Bangle

• Oxidised (finish in Jewellery) - An oxidised finish in jewellery, particularly gold, refers to a surface treatment that intentionally darkens or blackens the metal surface to create an antique or vintage look. The process involves using a chemical solution to speed up the natural tarnishing or corrosion of the metal, resulting in a dark, matte or semi-matte finish.
  
  In gold jewellery, oxidised finishes are typically applied to lower karat gold alloys, such as 14k or 18k gold, rather than higher karat gold, such as 22k or 24k gold. This is because lower karat gold alloys contain more base metals, such as copper, which are more reactive and prone to tarnishing.
  
  Oxidised finishes in gold jewellery can create a wide range of looks, from a subtle aged patina to a more dramatic blackened finish, depending on the strength and duration of the chemical treatment. This type of finish can add depth and character to jewellery designs, and is often used to create contrast between different elements or textures in a piece.
• 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.
