Gemology - A precious pastime for 3 to 7 players!

About Gemology, from BoardGameGeek:

In the game of Gemology, 3 to 7 players collect precious gemstones of various cuts and colors. Gem symbols represent popular cuts used in the jewelry industry, and each color represents a specific stone. Players track progress with colored cubes on a score card, and gems are acquired by playing pairs of cards. Before cards are played, each player passes one card to the player on their left, and another to the player on their right to influence their neighbor's progress (and lots of surprises!). Average game play is 15-30 minutes. Made in USA for 3-7 players age 8+. -description from the publisher
