Gemstone Crab in Tlati: Social PvM for Gems & XP

Yo, what’s good, fellow scapers? I’ve been sinking hours into Old School RuneScape’s latest gem in the Varlamore update the Gemstone Crab in the Tlati Rainforest. Dropped on July 23, 2025, as part of The Final Dawn, this shiny boy is hands-down one of the chillest PvM activities I’ve ever done. Picture a giant crab covered in sparkly gems, just begging to be whacked for loot and XP, with barely a fight back. It’s perfect for kicking back with your mates, grinding solo, or just vibing in a packed world. I’ve been chasing this crusty dude all over Tlati, and I’m hyped to share the full scoop how to find it, smack it, and cash in on those sweet gems. Let’s dive in with a guide packed with tips, a loot table, and some FAQs to sort out any head-scratchers.

What’s the Deal with the Gemstone Crab?

So, the Gemstone Crab is this massive, blinged-out critter roaming the Tlati Rainforest in Varlamore. Think Rock Crabs but with a glow-up, like they hit the jackpot at a gem mine. It’s not your typical boss with big scary mechanics nah, this crab’s more like a loot piñata. It’s built for social PvM, meaning you can team up with randos or your clan in multi-combat zones and just go to town. The crab hits like a wet noodle (0 or 1 damage, lol), so it’s super noob-friendly, but the real trick is dealing enough damage to rank in the top 16 players for the good stuff.

It spawns in three spots around Tlati: south and east of Tal Teklan, and north of Kastori. The crab chills for 10 minutes before it yeets itself underground, leaving a gem rock you can mine for uncut gems opals, sapphires, even dragonstones if RNGesus smiles on you. If you wanna keep the party going, chase it through a nearby cave or hunt for its next spawn. It’s like a treasure hunt mixed with a group beatdown, and I’m here for it.

Getting Ready to Crab

Before you go crab-hunting, here’s what you need to bring to the table:

Quest Prereqs: You gotta finish The Final Dawn to even step foot in the Tlati Rainforest. That means grinding through the whole Twilight Emissaries questline check the OSRS Wiki for the list if you’re behind.
Gear:
- Any weapon will do since the crab’s got no real defenses. I’ve been rocking a Rune Scimitar for melee or Fire Bolt for magic on my alt.
- Pack a pickaxe (Dragon or Crystal if you’re fancy) to mine the gem rock after the fight.
- A gem bag is a game-changer holds 100 uncut gems so you’re not juggling inventory space. Snag one from Motherlode Mine or Prospector Percy.
Skills:
- Mining 40+ to mine the gem rock (higher levels make it quicker).
- Combat level 40+ helps you hit harder, but even fresh accounts can tag along.
Getting There:
- Hop on the Quetzal transport for a quick trip to Varlamore.
- Or use a Skills Necklace to the Farming Guild, then hoof it across the Kebos Lowlands bridge.
- An Amulet of Glory gets you close to Shilo Village for banking gems later.

Hot Tip: Jump into a busy world like 302 or 330. More players mean faster kills, and it’s way more fun with a crowd yelling “crab down!” in chat.

How to Smack the Crab and Score Loot

Chasing down the Gemstone Crab is super straightforward, but here’s how I’ve been doing it to maximize my haul:

Track It Down: The crab pops up in one of three spots south or east of Tal Teklan, or north of Kastori. It’s a giant glowing crustacean, so you can’t miss it. Look at the timer bar above its head to see how long it’s sticking around (10 minutes tops). I usually check the OSRS Discord or clan chats for spawn callouts to save time.
Lay the Smackdown: Hit it with whatever you’ve got melee, range, magic, doesn’t matter. The crab’s got no real stats, so you’re pretty much guaranteed to hit your max damage every swing. It barely fights back (0–1 damage, pfft), so you can go full DPS mode without worrying about food or prayer. Your goal is to rack up as much damage as possible to make the top 16 leaderboard.
Follow the Trail: When the timer runs out, the crab burrows underground, leaving a gem rock behind. You can either chase it through a nearby cave to keep fighting or scout the other spawn points for its next appearance. I usually stick with the cave it’s faster and keeps the rhythm going.
Mine Those Gems: If you’re in the top 16 damage dealers, you get to mine the gem rock for three random uncut gems. Anything from junky opals to shiny dragonstones can drop. Make sure you’ve got a pickaxe and space in your inventory or gem bag gems that fall to the floor vanish quick. I learned that the hard way when I lost a dragonstone to a full invy. Ouch.
Keep Grinding: The crab respawns every 10 minutes, so you can loop between spawns for hours. It’s a chill grind, perfect for Netflix on one screen and OSRS on the other.

Heads-Up: No Dwarf Multicannons allowed here Jagex wants you to get hands-on. Also, don’t hold your breath for a pet; this crab doesn’t drop one, which is a bummer but keeps the focus on gems.

What You Get: Loot and XP

The Gemstone Crab is a goldmine for both XP and loot, especially if you’re into low-effort grinds. Here’s the breakdown of what you’re working with:

Reward	Description	Details
Uncut Gems	Random drops from opal to dragonstone.	Top 16 damage dealers mine 3 unnoted gems per kill. Gem bag saves space. Average value: ~450 GP per rock.
Combat XP	Chill way to train combat.	3.5 XP per 1 damage (87.5% of normal XP). Expect 50k–80k XP/hour depending on your gear and level.
Mining XP	XP from mining gem rocks.	~65 XP per rock at 40 Mining. With a Dragon pickaxe and 70+ Mining, you can hit 10k–15k XP/hour.
Social Vibes	Group PvM with zero stress.	Great for clan hangs or making new friends in multi-combat zones. No sweaty gear needed.

Gem Values (Grand Exchange prices, give or take):

Uncut Opal: ~150 GP
Uncut Jade: ~200 GP
Uncut Red Topaz: ~2,000 GP
Uncut Sapphire: ~250 GP
Uncut Emerald: ~500 GP
Uncut Ruby: ~1,000 GP
Uncut Diamond: ~2,500 GP
Uncut Dragonstone: ~12,000 GP

On a good day, you’re looking at 50k–150k GP/hour, depending on how many dragonstones you snag. With a high Mining level (70+) and a Crystal pickaxe, I’ve pulled 400–900 gems/hour, which can net up to 400k GP/hour if the GE is kind. Combat XP is solid too my main’s been getting ~60k Attack XP/hour with a whip, and my alt’s pushing 50k Magic XP/hour with Fire Bolt.

Grind Hacks:

Slap on a Toxic Blowpipe or Fire Surge to climb the damage leaderboard faster.
Pair a gem bag with Karamja Gloves 3/4 for quick banking at Shilo Village’s deposit chest.

Tips to Crush It

After a few sweaty sessions chasing this crab, here’s what I’ve learned to make the grind smooth:

Squad Up: Hit a busy world and team up with others. More players mean the crab goes down faster, so you’re mining gem rocks left and right. Clan chats like “CrabHunters” or Discord groups are gold for finding spawns.
Inventory Prep: I always carry a pickaxe, gem bag, and a teleport (Glory or Skills Necklace). Leave a few slots free for gems, or you’ll be crying when that dragonstone hits the dirt.
Spawn Hunting: The crab’s random spawns can be annoying. I keep a mental note of the three spots and check caves first before running around. Join a PvM Discord for real-time spawn pings it’s a lifesaver.
Low-Level Love: If you’re rocking a low combat level, don’t sweat it. I’ve seen level 30s tag the crab and still make top 16 on quiet worlds. Just bring a decent weapon like a Mithril Sword or Water Blast.
Ironman Goals: For my iron bros, fletch those opals and jades into bolt tips between kills to free up gem bag space. Save the high-value gems for Crafting dragonstones are clutch for Glory amulets.

Why I’m Obsessed with This Crab

I gotta say, the Gemstone Crab is my kinda content. It’s not some tryhard boss like Zulrah where you’re praying not to die and lose your bank. It’s just pure, relaxed fun whack a crab, mine some gems, chat with randoms, repeat. The Tlati Rainforest is gorgeous too, with all those tropical vibes and a cheeky Moana nod in the crab’s examine text (“He’s a shiny guy!”). It’s perfect for clan nights or when you just wanna grind without stressing over mechanics.

For ironmen like my alt, the gems are a Crafting godsend, and even my main’s been banking decent GP selling rubies and diamonds. Plus, it’s so chill you can train combat while half-watching YouTube. What’s not to love?

Frequently Asked Questions

Q: Do I need to finish The Final Dawn to fight the Gemstone Crab?
Yup, you gotta complete The Final Dawn to unlock the Tlati Rainforest. That means knocking out the Twilight Emissaries quests first check the Wiki for the full lineup.

Q: Can I take on the crab solo?
For sure! It’s great for solo or groups. On quieter worlds, solo players can easily hit top 16, but teaming up makes kills faster and more fun.

Q: What’s the best way to hit the crab?
Doesn’t matter melee, range, or magic all work. I use a whip for melee or Fire Bolt for magic, but even a basic Adamant Dagger gets the job done.

Q: What happens if my inventory’s full when I mine the gem rock?
Gems drop to the floor and despawn fast, so use a gem bag or leave inventory space. I lost a ruby once because I forgot to bank don’t be me.

Q: Is this good for ironmen?
Heck yeah! You’ll stock up on gems for Crafting, and fletching opal/jade bolt tips keeps your gem bag free for the big-ticket stuff like dragonstones.

Q: Why no cannons?
Jagex blocked Dwarf Multicannons to keep it hands-on and social. Gotta swing that sword yourself, you know?

Q: Any chance for a pet drop?
Nah, no pet from this crab, which kinda stinks. The loot’s all about those uncut gems, though.
