It obviously has a strong conchoidal fracture. Amber will fracture conchoidally to some degree, but not usually as strongly as seen in the picture. It looks more like glass or a something very high in silica. Obsidian is a natural glass and can sometimes be that colour. Man-made glass of that size would almost always have visible bubbles in it, which you wouldn't see in obsidian (or high silica minerals).
As Tpmetal says, a red hot needle poked into it will tell you if it's amber. It will leave a small indentation and you'll get a whiff of something pleasantly aromatic.
Gold would be nice, but I assume AARC is just teasing ya. Gold nuggets aren't translucent, don't fracture conchoidally, and a 4x5x6 inch nugget would probably weigh around 50 pounds

personally I don't see how any of us can comment on such a poor picture. The one you posted could be chocolate jello as far as I can see.
