is it going to be an new event to get these or i can buy them with gold ?

Hello once more. You can often get them on events. Or you can get them in silver shop -> gems(in the middle of page). If you want to get them in gold shop- it will be around 400 gold for any of it. But! iw will be only gem +0. to enchance it you need to buy scroll of ecnhancement.(~250 silver in SShop or get them in events.) Also in Sshop you can get gems from +0 to +4.
You can get 1 gem from another. To synthesis you need scrolls of changing gem of the seeker(they're in box with ur gem and also can buy with silver.) Самоцвет искателя опыта --> Самоцвет искателя богатства ----> Самоцвет искателя предметов ---> Самоцвет искателя опыта.
