You are using the gems app right ? It's easy you just create your counterwallet ("create a wallet") once you have a wallet you see your public key on the top right of your wallet assets. Then you can just send your Gemz to this address.
Let me know if you experience any difficulty
I'm sending from koinify and poloniex, i don't see anywhere 'create a wallet' in counterwallet, there is only 'create new address' and 'import funds' which talks about private key import and stuff.
A counterwallet address IS a bitcoin address.
Just send a counterparty asset to one of your counterwallet addresses, and the asset will show up in that address.
So can i just send my Gemz to the address below, "My address #1"? Where will the gemz go when the funds is received, i means should't there seperate Gemz space like BTC and XCP?
