While inconvenient, this is not a violation of any of our policies. Do keep in mind that the player taking this action is also taking a risk - it's not guaranteed he'll be able to sell any of those gems for the price he is asking. Players might consider it too expensive, or other players may create their own gems and sell them at a lower price.
