The Gryphon Tuckbox Edition of the game is the same as the original version but there are 5 cards in each color of gem instead of the 5 plastic gems of each color.

What do the best gem dealers in the world do when their discriminating clients demand the finest of gems for their prized collections? Everything they can - and anything they have to.
Gem Dealer is a game of strategy in which players collect priceless gems through a bidding process that involves cunning, calculation and a bit of bluffing. But bidders beware! The risks you take might pay off, or they could cost you a fortune.
Gem Dealer combines fun and suspense and daring and luck. But only the shrewdest Gem Dealer of them all will walk away in the end with the winning collection.
