|Rare Gem type||Limited|
When the player begins a game with Sunstone activated, a random number of unique yellow gems that resemble eight-pointed stars drops alongside the other gems into the board. A star functions identically to a Flame Gem, except a star also clears extra gems in the cardinal and diagonal directions. The base value for clearing a star is 600 points. While Sunstone is active, stars replace random yellow gems throughout the game, and Flame Gems created using yellow gems become stars instead.
After the Last Hurrah, a Coin bonus occurs in which nine star 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, 3,000, 6,000, 10,000, 20,000, 50,000, 75,000, 100,000, and 200,000.
- The name of this Rare Gem is a pun on sunstone, a chatoyant gem consisting of feldspar.
