Diamond

The Diamond is a money item worth $1000, the highest value of any coin.

Lucky Spin Achievement
Lucky Spin is an Achievement that you get when you roll three diamonds in Slot Machine. It is arguably the hardest achievement in the game because one diamond is very rare, and three is even rarer. In XBLA, however, you just have to get a diamond. It won't give you anything, but two diamonds will give you one. The PS Vita version, however, does not involve diamonds to get the achievement; instead, 3 of a kind in general will get it.

How to get it

 * Kill a Zombie Yeti (4, 5 if first time)
 * Grow a Marigold to the max. (1)
 * Grow a normal plant to the max. (2)
 * First time complete Mini-games, Survivals or Puzzles (1)
 * Find Crazy Dave's Magic Taco on 4-4 (1)​
 * Every 3 streaks in I, Zombie Endless or every 10 streaks in Vasebreaker Endless (1) (not always)
 * Every 3 streaks in I, Zombie Endless or every 10 streaks in Vasebreaker Endless (1) (not always)

Trivia

 * Diamonds have a "gleam" when they've yet to be picked up.
 * When a diamond appears, a chiming noise occurs.
