Ranked Rewards Question

Ranked season ended a couple days ago. If I go into a ranked game and I happen to suffer a loss streak that demotes me from Gold, will I still receive the ranked rewards for reaching Gold since I hit that rating and was Gold on Nov 12? Pretty sure I'll be fine in ranked but if it's going to risk my ranked rewards there's no reason for me to grind a bunch of ranked games until I'm sure I'll get what I worked for so far.
