Hi, thanks for your compliment. The pendant has been created with a process called casting. It's really pretty simple. You need a mold and casting resin, which can be bought at any large craft store or even from the internet. It includes two products (epoxy/resin and hardener) that are mixed together and harden like glass within a couple of days. A chemical reaction occurs when mixing the two liquids and years ago the odor was pretty awful and actually harmful if not used in a ventilated area. Now however a newer version advertises a 'low odor' and it's much better to use. It's a fun process, but you have to layer and work sort of backward and be certain to mix exactly as the directions instruct. If you try it, let me know what you think!
