It was handed down to me but with no info or documentation.I'd say it is real.
It's a real clear thing, sitting on a real box, held by a real hand.
Might be a large natural diamond, a synthetic diamond, some glass, plastic, acrylic, glopped-together superglue, or even ice.
But yeah, it's real alright unless you have a magic camera that can photograph things that are not real.
IOW ... when you ask whether it's real please state ........ a real what.
Where did you get it?
What did you pay?
Reasonable questions.
