The Lab Tag is built of German silver with a florally engraved background. The standard size is 1.5x2". If you prefer a different size be sure to let us know in the notes on the order form. All of our tags are hand-engraved. You will be able to tell with the finished product! This tag comes with 2 stones. After you place your order, we will create a design proof and send it to your email to confirm before we begin on the tag.
