A non-destructive test is to use an ultra-violet light (I bought one of these fairly cheaply at a local shop that sells electronics). Ivory has a distinctive blue sheen, which resin does not have: I recommend a bit of practice, shining the lamp on plastic, bone, etc. so you can see the effect.
Incidentally, horn shines light brown when lit by ultra-violet light. Which is a useful test if you can't decide whether something is made from horn or wood. |
