Details are unknown. This item has been stored at home for over several decades, and I believe it has dirt and scratches. I cannot determine whether these are original or due to aging and cracking. When I touch it, fragments fall off. The weight is over 2kg, as my home scale can only measure up to 2kg and gives an error. Thank you. Please be aware that fragments may fall off during shipping. #RawStone #PowerStone #Mineral #MossAgate #Chalcedony #BrecciatedJasper #Agate #Fluorite #Fluorite #PetrifiedWood #Tourmaline #Schorl #Shungite #PetrifiedWood
