Black Spinel stone is a rare gemstone made up of hard vitreous magnesium aluminium oxide or magnesium aluminate. Specifically, black spinel is one of the rarest minerals that comes from the Spinel family and is a true gemstone often confused with black tourmaline. It’s said that the name ‘Spinel’ comes from the Latin, ‘spina’ meaning thorn – this refers to the sharp crystal formations it’s made up of. Black Spinel is perfect for those who have problem in moving on from certain tragedy or sadness due to loss. Mentally, it also offers great benefit. Through its properties, it helps to improve the intellectual power and to reduce the forgetfulness that often happens due to lack of focus and concentration. Will be sent in a gift box. Thank you for looking at my jewellery.
