I think it's stupid you need to go diamond to check you insights
Is there a way to see if you've ever played a brilliant move?

People get all excited over the "brilliant" label. Here on chess.com, it doesn't mean you played a brilliant move. It means you played a decent sacrifice. They should relabel it "Decent Sacrifice."
Brilliant (!!) moves and Great Moves are always the best or nearly best move in the position, but are also special in some way. We replaced the old Brilliant algorithm with a simpler definition: a Brilliant move is when you find a good piece sacrifice. There are some other conditions, like you should not be in a bad position after a Brilliant move and you should not be completely winning even if you had not found the move. Also, we are more generous in defining a piece sacrifice for newer players, compared with those who are higher rated.

Why does it say for me that i have about 4500 brilliant moves theres no way i have that many, i do not have premium so is this fake or real

It seems likely that you are looking at summary numbers for some grouping.

there's a new feature, called insights. There you can see how many brilliant moves you have ever made.
Can I see the moves or I can only see how many they are?

These are Hikaru's stats dude

does anybody know how to see the games that you got the brilliant's in?
Go to insights once in you get premium, let them load, then scroll down to moves and move type, you should find it in that area
if this doesn’t work then sorry

Yes, as was explained several times previously in this thread, you can adjust the date range for Insights to make it easier to locate games where you played a decent sacrifice.
If you figure out that you have had a brilliant move/ decent sacrifice in the last 30 days, you can adjust the custom date range to locate the date where you will find the game. You can also find out what color you were playing.
Even after you narrow down the date range, if you play 100 games a day, you will still have to go through a bunch of games to find it.
As was said previously, brilliant moves aren't really brilliant. They are just decent sacrifices.

Could someone please gift me diamond so I could see how many brilliant moves I have?

You have to have a diamond membership to get it.

I have a diamond membership so I can see my insights which mean i can see how many brilliant moves i have ever gotten. However, yesterday, I checked and it said 9, two minutes ago i got another brilliant and i waited a bit, refreshed my page and checked my new amount of brilliants but it still said 9
