Ilvaite (that first letter is an “i”) is akin to Black Tourmaline – and “out-of-the-box,” it’s a more powerful version of it – also much more rare (and expensive). It has a distinctive bowing termination, and is often tighter in formation than Tourmaline (ie. not ever flaky, as can be the latter). It’s associated also (as is Black Tourmaline) with boundaries, but it’s more proactive in setting limits…can be used more as a wand (projecting energy) rather than more static, in simply defining space.
