Mikimoto Akoya Pearl Sterling Silver Maple Leaf Brooch, Hallmarked

• 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.
• Maple - Maple, native to North America, is a dense heavy timber from light to yellow-brown in colour. It has very little distincive graining unless it is one of the variants such as birds-eye maple or burr maple, so was not used extensively for furniture in 18th and 19th century, where cabinetmakers and designers preferred timbers with more distinctive features such as mahogany, walnut, rosewood and oak.
  
  Birds-eye maple has a seres of small spots linked by undulating lines in the grain, is highly sough and is used as a decorative veneer. Burr maple has larger and irregular grain swirls than birds-eye maple.
