Garnet is known as a silicate mineral and can from in several different classifications. This one specifically is almandine garnet. Pliny the Elder (23-79 AD), Roman historian & naturalist, mentioned the mineral alabandicus was found in Asia Minor around the city of Alabanda (from which the word 'almandine' is derived) which is present day Turkey. Garnet in general is known to be a grounding stone with its earthy dark red color connecting it to the Root Chakra.
These garnets are from the earth in Brazil where they were tumbled to be polished. Each one is unique, photos are an example of what you will receive. They are super dark in color and may only appear red when held up to direct light ( i love setting them on my phone flashlight and see how they glow!) One of my absolute favorite grounding minerals. They range in size but they are each about .5-1 inch.
