In a time when ivory poaching（偷猎）has gotten so bad that it threatens to wipe out several animal species,a young Dutch designer is creating "egalitarian（平等主义）jewelry" made of our very own ivory—teeth.

Lucie Majerus got the idea for her "human ivory" collection after having her wisdom teeth removed.She kept them and soon realized they would make great material for a jewelry collection."Why wouldn't we value our own material instead of the precious material from other species?And what if we mine our own ivory and turn it into pearls?"she asks.

Her own teeth became a ring,but in order to create a whole collection,she needed more material,and since having more of her teeth removed wasn't a very pleasant choice,she asked her dentist to save his patient's unwanted teeth.Most people choose not to keep their pulled teeth,so they are usually donated to dentistry schools.Majerus also received the lost teeth of two of-her teachers at Design Academy Eindhoven,so she had a nice supply of human ivory to experiment with.

To turn human teeth into attractive pieces of jewelry,Lucie Majerus first bleaches（漂白）them,and then uses a stone polishing machine to shape the teeth into various shapes.

Majerus displayed her human ivory jewelry collection at this year's Dutch Design Week,and claims that people's reaction was mostly positive."Surprisingly,most people aren't frightened at the sight of the jewelry,but really like the idea,"Majerus told Fast Co Design."Some regret that they didn't keep their tooth at the dentist and some,who will have teeth taken out soon,are now looking forward to it."
