|Rare Gem type||Limited|
When the player begins a game with Stemerald activated, a special starting layout appears. The configuration includes unique green gems that resemble seeds. A seed functions identically to a Flame Gem, except a seed clears all the gems above and within its column instead. The base value for clearing a seed is 6,000 points. While Stemerald is active, seeds replace random green gems throughout the game, and Flame Gems created using green gems become seeds instead.
After the Last Hurrah, a Coin bonus occurs in which nine seed icons appear in a 3×3 arrangement. When the player selects an icon, it reveals a numerical Coin value that is then added to the player's Coin total. The Coin payouts the bonus offers are 1,000, 5,000, 10,000, 15,000, 25,000, 35,000, 50,000, 100,000, and 500,000.
- The name of this Rare Gem is a portmanteau pun on stem and emerald.
