ARC Raiders: How to Get Red Coral Jewelry – Best Buried City Farm Route

Red Coral Jewelry is a rare (blue) trinket in ARC Raiders, and the fastest way to get it is to farm indoor furniture containers in Buried City — drawers, cabinets, shelves and lockers inside Residential, Old World and Commercial interiors. The single biggest multiplier is the Bird City map condition, which turns Buried City’s rooftop chimneys into lootable bird nests packed with trinkets.

One thing has changed since most guides for this item were written: the Avian Alarm project has ended. It ran from April 28 to May 26, 2026 as a limited-time Riven Tides project, and Stage 5’s 3x Red Coral Jewelry turn-in is no longer available. If you came here to finish that stage, that ship has sailed. What Red Coral Jewelry is now is a straightforward high-value trinket you farm to sell — and the route below is still the fastest way to stack it.

Everything here reflects the current live build, Hotfix 1.36.1 (July 9, 2026), inside the Riven Tides content period.

What Red Coral Jewelry actually is now

• Type: Trinket
• Rarity: Rare (blue)
• Loot zones: Residential, Old World, Commercial
• Best map: Buried City
• Current use: Sell trinket. The Avian Alarm turn-in it was tied to expired on May 26, 2026.

That last point matters more than it sounds. When a project is gating an item, you farm to a number and stop. Now there is no number — you are farming a sell item, which means route efficiency per raid is the only thing that counts, and it is worth combining the run with whatever else you need out of Buried City rather than doing dedicated jewelry laps.

Bird City is the condition that actually matters

A lot of older advice tells you to prioritise Night Raid, Electromagnetic Storm or Cold Snap for trinket farming. That is not right. Those are hazard and visibility conditions — they change how dangerous a raid is, not what spawns in furniture. The condition that genuinely changes trinket yield is Bird City.

Bird City is exclusive to Buried City and rotates in on a timer (community trackers put it at roughly one hour in every eight). While it is live:

• Rooftop chimneys become lootable containers, because birds have nested in them. Coverage from testing runs puts the share of searchable chimneys near 90%.
• Nest contents skew hard toward trinkets — including Red Coral Jewelry and the unique rubber ducks that sell for thousands of coins each — plus nature items (lemons, olives, apricots, prickly pears, mushrooms) and basic crafting parts.
• Critically, nest loot appears to sit outside the normal loot-area system that governs interior container quality. A weak building-loot sector does not drag chimney yields down with it.
• The map also gets more ziplines, more birds (including soundtrap birds) and more flying ARC, so the whole raid shifts onto rooftops.

If Bird City is up, drop everything else and run rooftops. If it is not, the interior route below is your baseline.

The Buried City interior route

Buried City wins because it stacks trinket containers close together. You are farming furniture density, not enemies. Work these in a loop and clear rooms properly rather than sprinting through centres:

• Santa Maria Houses. Room by room. Bedrooms, kitchens and living rooms all count — the jewelry hides in small household containers people skip.
• Grandioso Apartments. The most efficient stop, because each unit repeats the same pattern: bedside drawers, kitchen cabinets, hallway furniture, shelving.
• Plaza Rosa and Piazza Arbusto. Commercial interiors. Check shop shelving and back-room storage, not just the obvious crates.
• Red Tower, Galleria and the Library. Dense northern stops that current route guides consistently flag for lockers, safes and filing cabinets.

Container priority, in order: red and green lockers, drawers, kitchen cabinets, wardrobes, coffee tables, shop shelves and visible items on display. The common failure mode in Buried City is moving too fast — Red Coral Jewelry has no special world model before you search a container, so skipping “boring” furniture is exactly how a good run comes up empty.

Backup maps when Buried City is contested

Buried City is the best map but not the only one. If the drop is bad or the lobby is hostile:

• Spaceport — Departures. The staff/breach room with the red lockers is the standout repeatable spot here, and it is well documented by route guides and player reports.
• Dam Battlegrounds — Ruby Residence and Pale Apartments. Dense residential clusters even where loot icons are missing.
• The Blue Gate — Village. Another Residential cluster; stay in the interiors rather than wandering the outskirts.

Beachcombing: technically works, practically slow

Beachcombing on Riven Tides with a metal detector can surface Red Coral Jewelry — that is confirmed — but the buried-loot pool is enormous and the search area is spread out. Every outlet that covers it says the same thing: it is a valid source and a bad plan. Do it if you are already on Riven Tides for something else and treat any jewelry as a bonus. Do not build a farm around it.

Mistakes that make the farm feel worse than it is

• Chasing the wrong condition. Night Raid, EM Storm, Cold Snap and Hurricane are risk modifiers. Bird City is the loot modifier.
• Farming open ground. The item is tied to indoor container density. Courtyards and wide streets are dead time.
• Skipping small furniture. Players hit obvious crates first. This item lives in drawers, cabinets and shelving.
• Leaving after one quiet stop. If Santa Maria is dry, keep the run alive with Grandioso before writing the raid off.
• Still farming for Avian Alarm. The project closed on May 26, 2026. Anything you pull now is sell value.

FAQ

Can I still complete Avian Alarm Stage 5?

No. Avian Alarm was a limited-time project that ran April 28 to May 26, 2026. Its Stage 5 turn-in — 3x Red Coral Jewelry, 2x Turbine Compressors, 4x Roots, 1x Sirena Dorata Ship Model — is closed.

Should I sell my Red Coral Jewelry?

With the project gone, yes — there is no documented crafting or project use for it on the current build. Keep one in the stash if you are the cautious type, sell the rest.

Does killing ARC drop it?

No. Every current source points to container looting, not enemy drops. Fight to clear access or survive extraction, but do not build the loop around combat.

What is the single best setup for farming it?

Buried City with Bird City active, light kit, free inventory slots, and a rooftop chimney circuit. Failing that, Buried City interiors on the Santa Maria → Grandioso → Plaza Rosa loop.

The short version

Buried City, interiors, small furniture, and Bird City whenever the rotation gives it to you. The players pulling the most Red Coral Jewelry are not the ones taking more fights or waiting on some magic weather condition — they are opening more of the right containers per minute. For the wider picture on what is live right now, our ARC Raiders hub tracks the current update, and if you want an active project to work on instead, the Forgotten Relics event guide covers the merit farm. The old Avian Alarm project walkthrough is still up as a record of what that event required, and Ship Models on Riven Tides covers the other collectible from the same period.
