How much is a 3 carat Leo Artisan diamond
$2500-$7500 per carat depending on cut and clarity. I can't believe I know that. Maybe I learned something from engagement ring shopping.
As much as the pawn broker is willing to give you, which is probably 25% of original price even if you bought it 3 seconds ago from the jeweler next door.
Probably start at $50,000 on up. Depending on clarity, color and cut
