On The Island, Silica Pearls can be easily found in the top left corner of the map (about 30 lat, 10 lon) they're seen as large white and blue stones in the water.

also put fur on cause its in an arctic zone, funny story on how i almost died in one of the stupidest ways possible

At roughly 39 59 on crystal isles you'll find thousands of them all clustered together.

On Crystal Isles, at about 42 40 there is a little white lake. There is a waterfall in the lake, and on either sides close to the waterfall are around 1000 silica pearls, + the ones in the beaver dams. Just be careful because in my case there was a Yuty pretty close by.

For Ark: Survival Ascended!

Angler fish + south & east side of the ocean I’ve had best luck obtaining decent amounts, it’s all scattered so no big pods/groups.

Ocean caves also have a good bunch! Make sure to bring a sickle as there’s tons (TONS) of grass/fiber that you have to harvest before you get the silica. Hope this help!

In ARK: Survival Evolved; Mobile, and even in the regular the Island, there is an Island in the south known as South Haven Island. It consists of purely herbivores, and pteranodons. There is always at least two ankylosaurus at one time, and often more, and the only creatures on the crescent-shaped island are triceratops, ankylosaurus, brontosaurus, parasaurolophus, pteranodon, many coelacanth, and most often, basilosaurus, ichthyosaurus, and megalodons, along with far-off leedsycthis. Titanosaurus will occasionally spawn there, and, if they step off of the back of the island, its slope is too steep for any dino to easily overcome. Furthermore, the numerous metal nodes respawn rapidly, much more quickly than anywhere else, and there are silica pearls in extreme amounts in the inner beach, which also respawn practically as soon as you look away. There are also large sections of the island where you can make massive bases, even along the sandbars. I hope that this helps, Wanderers. From.: OMEGA, Hunter of Shadows.

go to the snow island at 30 lat, 10 lon. There are tons of trilobites which drop silica pearls and black pearls. white and blue rocks in the water (not the white and black oil rocks) can also give you silica pearls. you also need silica pearls for yuty saddles for bosses. Hoped this helped!

Beaver dams also have a chance to give silica pearls too.

For ASA players on Scorched Earth:

Check the Obilisks. I personally found the most pearls at the Red one.

If you are on the island with hydrophobia go to the arctic. It has close-to-shore lakes with silica pearls in it I got my chemistry bench and haven’t been near the deep ocean

On the island got to the south shore of herbivore island. I got around 600 in one trip

If you got to the west Ocean if the Island, you can find an underwater cave containing thousands of not tens of thousands of silica pearls. Just use your hand to collect them you’ll never need more!

Rag 75, 23 sea floor has more then you can carry also rob beaver dams

Why are these so hard to get in asa

On mobile you can find them on beaches and shorelines instead of underwater

The place where you will find the most silica pearls guaranteed thats not in the ocean is in the river in the northwest part of the map. Warning that this river is for the most part head deep and murky in some parts even on old ark mobile and it cuts through some cold areas so you need fur or scuba pants. If you go to the pond area next to the snow cave you will find loads but spinos or barys can spawn. If you head up north all the way to where the river ends then turn east there's also alot of silica pearls on the shores. On pc and ume silica pearls can't spawn on herbivore island.

However if you dont wanna fly all the way to the corner of the map you might as well tame an angler since 95% of the silica pearls on the map are in waters that are head deep or deeper and can fit an angler, chances are the closest silica pearls to your base are in the ocean, you can ride them without a saddle, they are fast enough to escape anything except tusos, alpha mosas and alpha tusos, and they can harvest 5x more silica pearls by biting them than a human can by picking them up. For example I only get like 20 silica pearls per clam I pick up but my angler gets more than 100 per clam. So just tame an angler any level can work.

In The morning you can go around shores looking into The water to find these shinkng goodies, one of The spots on [The Island] is 34.7 17.1 another great spot for them is herbivore island however im not sure if there are any since i collected pearls earlier and forgot from where

On ark mobile there’s oysters on the beach harvest them and u get like 9-15 pearls per oyster

Hope this helped

Above the dwarven statue on fjord is a lake in there are butt tons of silica pearls

Scorched Earth:

They can be found along the riverbed. They don’t glow like they do in other maps. They blend in, but look like dried up clams.

Just comb the beaches. You’re bound to find them just about anywhere save the east side of the map. Anglers are amazing at farming these. Would recommend taming one if you’re hard pressed for pearls
