<human>: How can I tell if a diamond is natural or fake?
<bot>: The best way to tell if a diamond is natural or fake is by looking at the cut and clarity of the stone. Natural diamonds have a symmetrical, well-defined cut with few imperfections, while synthetic diamonds are often poorly cut and may have visible inclusions in the crystal lattice structure. Additionally, a diamond's color should also be taken into consideration; natural stones will typically display an even hue throughout, while synthetic diamonds may have a colored tint that varies depending on the type of material used to produce it.
