Lemurian Quartz Crystals, also known as Lemurians/Lemurian Seed Crystals/Lemurian Starseed Crystals, were first found in the Diamantina region of Brazil. I have recently read that Lemurians have since been found in other areas of the world.

They have a very distinct appearance, and while natural, unpolished crystals are often quite cloudy or misty with horizontal grooves or striations resembling barcodes on one or more sides, when polished they are super sparkly and gorgeous.
