Soulstone's a type of stone, whereas that's a crystal. That's pretty weird actually, aren't crystals amorphous?

I've read that it's an Aether from Yolen. Which would be kinda hard to come by, so maybe not.

Mraize's collection has been an interesting topic of debate. We all know that they're items from around the Cosmere, generally relevant to their planet's magic systems.

Other curiosities baffled her. A vial of pale sand. A couple of thick hairpins. A lock of golden hair. The branch of a tree with writing on it she couldn't read. A silver knife. An odd flower preserved in some kind of solution. There were no plaques to explain these mementos. That chunk of pale pink crystal looked like it might be some kind of gemstone, but why was it so delicate?

Most of them are pretty obvious; the pale sand is from Taldain, the flower is a Tear of Edgli from Nalthis. There are however a few that we do not fully understand; the pink crystal, the lock of hair, and most notably here, the hairpins.

General consensus is that the hairpins are Hemalurgic spikes from Scadrial. The fact that they are described as "hairpins", however, is unusual. A think hairpin would likely have a diameter of perhaps two centimeters, and not much longer than twenty centimeters. Far smaller than you would expect an Inquisitor spike to be.

Being in Mraize's collection, it is unlikely that they're just random spikes off-world, and it is even more unlikely that Mraize created them for enhancement, otherwise they would be stored in blood to preserve their charge. They must be from Scadrial, and they must have some sort of special significance there.

So what are they?

A Kandra Blessing.

TenSoon stuck a paw into the depression, digging out the ash, working to uncover the things he had hidden a year before. He found them quickly, rolling one—then the other—out onto the rock shelf in front of him. Two small, polished iron spikes. It took two spikes to form a single Blessing. TenSoon didn't know why this was. It was simply the way of things

Let's look at that description again.
