Rough Gem is a Diamonds-oriented Joker which gives the player $1 for each 
Diamond scored.
Synergies[]
Decks[]
Checkered Deck cannot benefit from Rough Gem due to a lack of cards with the Diamond suit.- Erratic Deck can benefit from Rough Gem if the deck is randomized to have more Diamonds than other suits.
Poker Hands[]
Playing any Flush with Diamonds will ensure maximum benefit from Rough Gem.
Jokers[]
Rough Gem directly synergizes with 
Greedy Joker, as both give bonuses for scoring Diamonds.
As with many money-producing Jokers, it directly buffs the effects of 
Bull and 
Bootstraps. It also, indirectly, powers up 
Flash Card, 
Red Card, 
Ceremonial Dagger, and other such economy-based scaling Jokers by producing more money to use in activating their effects.
As Rough Gem produces money mid-round, it works very well with 
To the Moon, as the money produced counts towards interest earned at the end of the round.
Any jokers that retrigger cards allows Rough Gem to activate multiple times on a single card (
Dusk, 
Hack, 
Seltzer, 
Sock and Buskin, or 
Hanging Chad).
Smeared Joker allows all 
Heart cards to count as Diamonds for scoring, letting Rough Gem work on more cards.
Splash can occasionally be useful, as the scoring of an additional Diamond that wouldn't otherwise score is extra money. However, you ideally want to be playing flushes, which Splash is useless for.
Trivia[]
- Rough Gem is one of four stone/mineral themed jokers unlocked by having 30 cards of that suit in your deck. The others are Arrowhead (spades), Bloodstone (hearts), and Onyx Agate (clubs).
- While Smeared Joker allows heart cards to count as Diamonds for the purpose of scoring, those cards do not count as diamonds for the purpose of unlocking the joker.
