Hi Mayna,
Every kit is weighed before packaging to ensure all the diamonds are included. While 1 or 2 colors can sometimes be missing, it is rare for a kit to be short of 8 colors. That being said, we still offered to send them to you free of charge as part of our Oops insurance policy. We also let you know that we would only be able to honor one claim for this kit and it is recommended to wait until you're closer to completion, but you insisted for the diamonds to be shipped right away. Due to that, we're unable to send you more diamonds for free and you'll need to cover 75 cents per pack as outlined in our Oops insurance page here: https://www.diamondartclub.com/pages/oops
Thank you,
The Diamond Art Club team
