Shakudo Enameled Sterling Silver Ring by Lisa Wetherall

• Shakudo - Japanese shakudo is a traditional alloy that has been used in Japan for centuries. It is primarily composed of copper and gold, with the copper serving as the base metal and the gold adding a yellowish hue to the alloy. Shakudo is known for its beautiful dark blue-black or black colour, which is achieved through the addition of a small amount of a patina-inducing element like silver or arsenic.
  
  The word "shakudo" itself can be translated as "red copper" in Japanese, referring to the reddish-brown color of the pure copper base metal before it is patinated. The gold content in shakudo is usually around 4-10%, but this can vary depending on the specific purpose or desired appearance.
  
  Shakudo has been traditionally used in various forms of decorative arts and crafts in Japan. It is particularly associated with metalwork, including sword fittings (such as tsuba, menuki, and kashira), jewelry, and small ornamental objects. The alloy's dark color provides a striking contrast to other metals like silver or gold, making it ideal for intricate inlay work or as a background for other decorative elements.
• 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.
• 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.
