Want to put this above a fireplace. It's pretty heavy, what's the best way to support it and look aesthetically good?

Depends what you find aesthetically pleasing? Scaffold brackets would be easy fix.
 
something like this. Sink the flats in wall maybe.

Bolt resin the long bit in wall is an easy job.

Wood will sit on 2 of these and screw in from the bottom

Maybe other similar brackets that maybe better
 
Offset pins, its like a rawl plug into the wall with pins into the mantel. You align the pins to make the mantle level, holds it no problem
 
Do you want it to look like it's floating (hidden supports) or do you want visible supports?
 
I prefer supported look, would be seeking some decorative carved triangular pieces myself.. "corbels" is probably the phrase you'd be googling for

Drill the wall, drill the edge of the timber to match the holes in the wall, then resin both in the wall and the timber holes, for the threaded bar.
It's heavy, I'll put two resins bars in. Never put a resin bar in before. How deep into brick work? How high above fire?
 
3 or 4 i would use.

4" min into brickwork and timber.

I would support it on a temporary frame whilst it dries, or you end up having a droopy result
 
The weight of the mantle creates a torque ( rotational force ) around the point where the resin bar connects the mantle to the wall.

If you use resin bars then put the bars close to the top of the mantle to create a force ( from the weight ) that presses the bottom of the mantle towards the wall if the resin bar starts to bend

With the resin bars close to the bottom of the mantle a force is created that pulls the top of the mantle away from the wall along with a force ( white arrow ) that presses the bottom of the mantle towards the wall. Worse case is the wall crumbles under this pressure and the resin bar bends
 
No need to worry about bending if you get the right bar, the right depth too. Use 4 bars too.
