I found this in the parking lot during a craft fair. Does anyone know what it is? I’m thinking it’s either pink kyanite or pink tourmaline, but I'm a amateur so I can’t differentiate between the two.

It’s pink with pieces of white inbetween it’s crevices and about two inches long.

  • $\begingroup$ There is a very distinctive hardness test for kyanite. Its hardness varies strongly with crystallographic direction. A knife will scratch it easily along the length of the crystals but not scratch across the crystals. Please let us know what the test shows. $\endgroup$ – haresfur Jul 24 '18 at 0:29

  • $\begingroup$ It was dropped by someone in said parking lot. I wanted to ask the seller what it was but all the vendors packed and left. I’m just the random who found and picked it up so how am I supposed to know where it was mined? $\endgroup$ – TeachMe Jul 24 '18 at 10:18
  • $\begingroup$ The fair was on Hawaii btw. So I’m sure the seller imported it. $\endgroup$ – TeachMe Jul 24 '18 at 10:28
  • $\begingroup$ so ok you cannot provide location of the mineral. Pink kyanite is rare, but can you make the suggested test with a knife? make a cross and tell us if it scratches more along the length of the crystals $\endgroup$ – user12525 Jul 24 '18 at 10:29

Your rock is most likely Rubellite, lithium rich member of the tourmaline mineral group.

Similar piece from my personal collection. enter image description here

    $\begingroup$ Not sure. I’m missing the striations, so hard for me to say it’s a tourmaline. $\endgroup$ – Gimelist Aug 12 '18 at 1:49
