Gem-Themed Slots
When you think about classic slot themes, you may think of ancient worlds, fruity symbols, and traditional Irish visuals, but gems and jewels remain one of the most popular categories. Glistening symbols pepper the reels as you play your way into a trove of potential payouts, reminiscent of old-school machines but usually complete with more modern features and mechanics.
These slots are immensely well-liked, but what is it about them that makes players enjoy them so much?
Visuals, sound effects, features, and even game providers make all the difference, and we’ve covered them all in our guide to gem slots.

Premium Symbols in Gem Slots
Naturally, top-paying symbols in gem-themed slot machine games are designed around the theme, offering luxurious icons that could land across paylines or in cluster formations to award payouts. Premium symbols offer bigger potential payouts than those lower down in the paytable, so keep your eyes peeled for some of the following jewels.
- Emerald
- Peridot
- Ruby
- Amethyst
- Topaz
- Sapphire
- Garnet
Standard Symbols in Gem Slots
The standard symbols on offer in a gem slot are largely similar to any other theme, but generally, they are given a luxurious makeover to tie them in nicely with the rest of the game.
Card values are one of the two most popular options for low-paying symbols among all types of slot machine games, notably jewel-themed ones, but only a handful of card values are usually covered:
- King
- Queen
- Joker
- 10
- 9
French card suits are the second of the common standard symbol sets, often with a glimmering upgrade to resemble a gemstone:
- Spade
- Diamonds
- Hearts
- Clubs

Top Gem Slots Bonus Features & Mechanics
Free Spins
Like in most other themes, free spins are a hot commodity in gem slot games. Often triggered with scatters, this feature offers a tide of gems and jewels that cascade into view without costing you an extra penny. These bonus rounds are valued at the triggering stake, so your free spins are just as valuable as your base game ones, granting you lots of extra chances to pocket valuable gemstones.
Multipliers
Multipliers could show up as you play through the reels of your favourite gem slots, boosting the value of any glittering payouts that occur in the affected spin. Some of these multipliers present as wilds, simultaneously substituting for the other paying symbols in the paytable and enhancing the prize amount if they contribute towards a win.
Clusters
Cluster-based titles bring a modern touch to the gemstone genre, offering payouts and prizes galore for shining clusters of matching icons. Usually, it’s at least 5-of-a-kind that are required for a cluster to qualify for a prize. Naturally, the more symbols in a cluster, the better.
Giant Symbols
What’s better than a standard-sized ruby? An enormous one! Giant symbols take over the reels, filling multiple positions to increase your likelihood of bagging a win or two. Generally, these supersized icons are selected at random, growing from the basic 1x1 size to 2x2 or even bigger, depending on the game!
