Jewelry for Green Thumbs. Do you ever look at a plant and think think that it needs to be shown off, like it's better than any gem or diamond? We can celebrate beauty with jewelry that cleans the air, and can be worn with plants found as close as your backyard. The idea for a wearable planter came from the search to create something meaningful out of plastic. Why make a disposable bottle from this material when we can be making heirlooms?
