This bronze ginkgo leaf bracelet highlights the beauty of this well-known leaf with its unique heart shape and delicate veining. Ginkgo biloba trees are among the most celebrated of trees, and for good reason. Not only are they breathtaking, but ginkgos are considered a living fossil, having no known living relatives, and having endured for millions of years with little change. They are the oldest surviving species of tree known to exist, with a history spanning 200 million years. Not surprisingly, it has become a symbol of strength, hope, and peace for many. We recommend adjusting this bracelet to the correct size and then leaving it alone. As with all adjustable jewelry, excessive opening and closing can weaken the band and create cracks and possible breakage. Our bronze is a high-quality Italian alloy of copper and tin that contains an anti-tarnish compound which delays, but does not eliminate, eventual oxidation.
