Please note: small marks on the gems are considered normal, it doesn't happen that much but occasionally there may be some small specks or a small mark.
Please consider this a sign of the hand work involved in making these blocks, it does not detract form the play value.
A cracked gem is definitely considered faulty, in the unlikely event you get one of those, please let us know.
