Pendant measures 1.7 inches. It is black nickel plated, hard enamel. Comes with a sterling silver chain which is adjustable to 16", 18" or 20." "IMPORTANT: Sterling silver is an alloy containing metals that react with chemicals found in air and produce tarnish; high moisture levels, exposure to sunlight and contaminants such as salt water increase this reaction. Take steps to protect your sterling chains by keeping them in airtight packages, use tarnish-resistant products (such as tarnish tabs or strips) that absorb harmful chemicals, and store sterling findings in a cool, dry place. Most tarnish is easily removed by polishing with a mild abrasive or soaking in an anti-tarnish solution." As all pendants/pins are hand painted, no one is perfect. Standard Grades are as near perfect as you can get. Thanks for looking!
