These bone pendants are carved with the Tree of Peace in a spearhead shape. They measure approximately 4.5" long by 1.5" wide. There is some variation from pendant to pendant as these are handmade items. You will receive ones similar to the photos shown, but not exactly the same.
To make it look antiqued, just put the pendant in a bowl, boil up a pot of tea, pour the tea on it and let stand for a few minutes. Drain the tea. Dry the pendant.
