Large Black Diamond spotted

Large Black Diamond spotted
Back in December, I was on the phone to my mother when I stopped mid sentence and watched a very large matte-black perfect diamond shaped object.

It moved slowly across the sky in a perfectly straight horizontal path, out towards the ocean (I live very close to the beach).

It was far too big to be a regular kite. It had no tails, tendrils or strings. No noise, lights, windows or smoke. Just a big black diamond.

It was a very clear summer, cloudless day. The diamond looked smooth, matte and “impossibly black” if that makes sense. As if it was absorbing light, not reflecting it.

I felt really uneasy as it flew across the sky in a straight line. What stuck out to me was it never rotated, titled or shifted up and down. 

Just a smooth, consistent glide like it was on an invisible moving walkway. Like what people stand on at airports. I hope that makes sense.

I opened the flight radar app while I was on the phone and it showed nothing at the time. No one else I’ve spoken to saw it. 

Has anyone ever seen something like this anywhere else?
