Mining Gem Rocks OSRS – Ultimate Guide to Gems and Profits
In Old School RuneScape (OSRS), mining gem rocks is a rewarding activity that combines decent experience rates with solid profits. Whether you’re an Ironman hunting for crafting materials or a main account looking to make some gold, gem rocks offer a unique mining experience. This guide covers everything you need to know about mining gem rocks, from requirements and locations to strategies, equipment, and profitability.
Gem rocks are special because they yield gems instead of ores, providing 65 Mining experience per gem mined. Unlike regular ore rocks, gem rocks are a reliable source of uncut gems like sapphires, emeralds, rubies, and diamonds, which are essential for Crafting and Fletching. They’re also profitable, with average earnings of around 400-700k GP per hour depending on your setup and efficiency. For players seeking variety from the usual ore grind or aiming for the Mining pet, gem rocks are a fantastic choice.
Key Benefits of Mining Gem Rocks
- Profitability: Gems can be sold on the Grand Exchange or used for crafting jewelry, offering flexible money-making options.
- Experience Rates: With tick manipulation, you can achieve up to 105k-115k Mining XP per hour at level 99.
- Ironman Utility: Gems are crucial for crafting jewelry and bolt tips, making this a go-to method for self-sufficient accounts.
- Pet Chance: Gem rocks have one of the best drop rates for the Rock Golem pet.
Requirements for Mining Gem Rocks

Best Locations for Mining Gem Rocks
Gem rocks are found in a few specific locations in OSRS, but the Shilo Village mine is the most popular due to its accessibility and high number of rocks. Below are the key locations and their pros and cons.
Shilo Village Mine (Surface and Underground)
The Shilo Village mine, located in the northwest part of the village, is the go-to spot for gem rock mining. It has two sections:
- Surface: Accessible after completing the Shilo Village quest. It has fewer gem rocks and no nearby bank, making it less efficient.
- Underground: Unlocked after the Medium Karamja Diary. This area boasts 48 gem rocks and a Bank Deposit Chest, allowing for continuous mining without world-hopping.
Pro Tip: Use Karamja Gloves 3 or 4 for a teleport to the mine, and bring a chisel to cut gems into bolt tips to maximize inventory space.
Lunar Isle Mine
Unlocked after completing Lunar Diplomacy, the Lunar Isle mine is a quieter alternative with fewer players. However, it has fewer gem rocks and no nearby bank, making it less efficient than Shilo Village. This spot is best for players who prefer a less crowded environment or are already on Lunar Isle for other activities.
Tai Bwo Wannai Cleanup Minigame
During the Tai Bwo Wannai Cleanup minigame, gem rocks can randomly spawn with a 5% chance per event. These rocks are unique because they have visible gems encrusted on the surface and can be mined three times before despawning. While not a primary method, they’re a nice bonus if you’re already participating in the minigame.
Strategies for Efficient Gem Rock Mining
To maximize your experience and profits, you’ll need to optimize your mining strategy. Here are some proven methods to get the most out of gem rock mining.
Tick Manipulation for High XP Rates
Tick manipulation involves using a 3-tick action (like fletching or dropping items) to speed up mining cycles. In the underground Shilo Village mine, this technique can yield 90k-115k Mining XP per hour at high levels. Here’s how to do it:
- Equip a Dragon or Crystal Pickaxe and a Charged Amulet of Glory.
- Bring a chisel and fletch uncut opal or jade into bolt tips while mining.
- Move counterclockwise around the underground mine, mining each rock.
- Drop unwanted gems (e.g., opals) to free up inventory space, or use a gem bag.
- Deposit gems at the Bank Deposit Chest when your inventory is full.
Note: Tick manipulation requires practice and high focus, but it’s the fastest way to level Mining through gem rocks.
Maximizing Profits
To boost your GP per hour, consider these tips:
- Use a Gem Bag: Store up to 60 uncut gems, reducing banking trips and increasing mining time.
- Fletch Bolt Tips: Cut opal, jade, and red topaz into bolt tips to save inventory space. This is especially effective in the surface mine where banking is less convenient.
- Check Grand Exchange Prices: Gem prices fluctuate, so always verify current market values before selling. On average, a gem rock is worth about 405.77 GP.
Inventory Management
Efficient inventory management is key to sustained mining sessions. A typical inventory setup includes:
- Dragon/Crystal Pickaxe
- Charged Amulet of Glory
- Gem Bag
- Chisel (for cutting gems)
- Optional: Food or stamina potions for long sessions
In the underground mine, you can mine continuously and deposit gems at the Bank Deposit Chest, making inventory management straightforward.
Profitability and Experience Breakdown
Mining gem rocks is both a profitable and XP-efficient method, especially with the right setup. Below is a breakdown of what you can expect based on your Mining level and strategy.
