A beautiful stone. Very high quality

More than 100% satisfied! They’re alive, beautiful and large. I’m saving this seller, to buy from again.

My son loved this. He is a 7 year old rock hound and the was so cool for him.

I was so disappointed. This looked like magnetite BUT it was not at all magnetic. That was the special property of being naturally magnetic I was trying to teach.

Six pieces a variety of sizes with one small piece. Raw and unpolished so excellent for teaching. I am using it for the magnetic healing properties so will be able to comment more on this later as I experiement with natural substances. Satisfied with the purchase as it was exactly what I wanted - raw, natural, untouched, unpolished. It may not be a decorative piece as my other gemstones, but it is perfect for my mini experiment.

Arrived quickly and was as described. Looks great happy with this product! Purchased for my collection

Si era lo que estaba buscando, buen producto y llego antes del tiempo programado. Excelente compra

Al parecer no es magnetita, ya que no atrae ni una grapa. Un imán si se atrae tal como lo hace cualquier material ferromagnético, aunque se gire no repele por ningún lado como debería hacerlo ya que debería tener dos polos.

Expensive and doesn’t have any magnetic resonance
