San Diego, La Jolla, Coronado and North County
Lost a ring or earring on a San Diego beach?
From the Coronado sand north past Mission Beach, La Jolla and the Encinitas bluffs to the Oceanside Pier.
An earring is the hardest thing on this coast to find and the easiest to find quickly. A stud gives a far weaker signal than a ring, so a searcher has to be over almost the exact patch, which makes the towel, the tower or the stairs you can name worth more than anything else you can tell us.
Ring Seekers is a lost ring and jewelry recovery service that works with experienced local metal detectorists to search for a ring, wedding band, watch or phone lost in San Diego, La Jolla, Coronado and North County. The detectorist who searches knows this stretch of the California coast. Tell us what happened and where. We choose an experienced detectorist who knows the beach, brief them with your map and photos, and tell you honestly if the odds are poor.
This page is for an earring and just as much for a lost ring, a wedding band, a bracelet, an Oura ring, a watch, keys or a phone.
How a search on a San Diego County beach works
In the first hour, fix the spot. Line yourself up with two things that do not move, a lifeguard tower and a set of stairs, and photograph each way. Drop a pin and note the time, then send that on WhatsApp with a photo of what you lost.
We choose an experienced detectorist who knows that beach and pass on your marked map. After that it is the tide that runs the timetable. This is a mixed tide coast, with a big drop between the higher high and the lower low, and in summer the lowest water comes in the early morning, so a wet sand search often starts not long after dawn.

Beaches from Coronado to Oceanside where rings go missing
Each stretch of this coast loses jewelry in its own way.
Mission Beach and Pacific Beach
Mission Beach is one of the most popular beaches in the city and Pacific Beach one of the busiest. Ocean Front Walk runs behind both, with Belmont Park at Mission Beach and Crystal Pier at the Pacific Beach end. We have had an enquiry from Mission Beach. Rings and Oura rings come off in the surf, and both beaches have permanent lifeguard stations, so a tower number makes an easy landmark.
La Jolla Shores and La Jolla Cove
La Jolla Shores is about a mile of sand with gentle summer waves and many beginner scuba classes, so rings, earrings and watches go missing at the water's edge while people pull gear on and off. La Jolla Cove is a very small beach between sandstone cliffs, with deep water close in. On the Shores sand a low tide grid is straightforward.
Coronado Beach and Silver Strand
Coronado Beach runs about 1.75 miles, from Dog Beach in the north to the jetty near the Hotel del Coronado, with the year-round lifeguard station at Central Beach. Silver Strand State Beach, further south on the spit, has 2.5 miles of ocean beach. Earrings and rings go missing during picnics on wide sand, which is good ground for a detector if the spot is clear.
Del Mar, Torrey Pines and Solana Beach
Del Mar City Beach sits below Powerhouse Park, with Dog Beach running north to Solana Beach and Torrey Pines State Beach south under the bluffs. In Solana Beach, Fletcher Cove at the end of Lomas Santa Fe Boulevard is the main way down, with lifeguards all year. This sand narrows a lot at high tide, so a ring dropped in the morning can be under water by afternoon.
Encinitas and Cardiff by the Sea
Moonlight State Beach is a wide, sandy beach run by the City of Encinitas. North of it, Stonesteps and Beacon's sit under bluffs and can all but vanish at high tide. In Cardiff by the Sea, Cardiff State Beach is a gently sloping sandy beach popular with surfers, and San Elijo State Beach is a narrow strip below a bluff top campground. Rings slip off while people wax boards or rinse after a surf.
Carlsbad and Oceanside
Carlsbad State Beach runs from Pine Avenue to Cannon Road, with heavy erosion there after summer swells. South Carlsbad State Beach has stairs down from its bluff top campground. In Oceanside the sand either side of the pier and Harbor Beach are busiest. The autumn harbour dredge was due to start on 15 September 2026, with the sand placed on Oceanside beaches, and a ring lost where the pipe is heading can end up far too deep to reach.
What you get from Ring Seekers along the San Diego coast
One person on WhatsApp
You explain it once, and the same person chooses an experienced detectorist who knows your beach and keeps you posted.
Your map and photos go to the detectorist
The detectorist gets your marked spot, your photos and the time before setting foot on the sand, which saves the first hour.
Plain about poor odds
A ring lost in the surf at high tide with no idea of the spot is a poor bet. We say so before you spend anything.
We plan around how this coast moves
Bluff beaches that go under at high tide, and winter swells that strip sand off North County, decide when a search happens.
Costs explained first
The cost reaches you while you are still deciding, not after.
Tide, sand and water from Coronado to Oceanside
What a detectorist works with on this coast.
Tides
NOAA station La Jolla (9410230): mean range 3.69 feet (1.1 metres), and 5.33 feet (1.6 metres) between the higher high and the lower low of this mixed tide. In 2026 predictions run from minus 1.9 to plus 7.2 feet. Inside the bay, San Diego (9410170) shows 4.05 feet (1.2 metres) and 5.72 feet (1.7 metres), and the lowest summer lows fall between about 2 am and 7 am.
Sand, cobbles and bluffs
Big winter swells pull sand off North County beaches, and Scripps researchers note cobbles usually surface in winter. A ring in dry sand tends to stay put; one in the surf zone is buried deeper with each swell. The bluffs at Torrey Pines and Encinitas shed rock, so a searcher works out from the base of them rather than against it.
Water temperature
Sea temperature off Del Mar averages about 59 F (14.9 C) in February and 68 F (19.8 C) in August. Cold water shrinks fingers, which is how most rings come off in the waves.
Wide sand and narrow sand
Coronado and Silver Strand give a searcher wide, open sand that can be gridded properly. Fletcher Cove, Del Mar and the Encinitas bluff beaches narrow to almost nothing at high water, so there the job has to fit into the hours around low tide.

Small things in the sand, from Coronado up to Carlsbad
I lost an earring on Coronado Beach. Is it worth a search?
Often, if you can place it. Coronado Beach runs about 1.75 miles between Navy beaches, from Dog Beach in the north past Central Beach and its year round lifeguard station to South Beach by the Hotel del Coronado, so tell us which section and which tower. A small stud gives a weaker signal than a ring, so the exact spot matters more than it would for a wedding band. A towel left on the patch keeps it findable until someone arrives.
I lost my wedding ring at Mission Beach or Pacific Beach. Where do I start?
With a landmark. Ocean Front Walk runs about 3.5 miles from South Mission Beach to North Pacific Beach, so note the nearest cross street and lifeguard tower. Do the same for an Oura ring or a watch that came off in the waves, and add the time, because the tide decides where the waterline was. A phone off Crystal Pier into deep water is a much harder case, and we will say so.
My earring came off at La Jolla Shores during a scuba class. Any chance?
A fair one on the sand. La Jolla Shores is about a mile of beach with gentle summer waves, and the beginner classes gear up in much the same place, so the patch you stood on is usually easy to name. At low tide a detectorist can grid that sand properly. Anything that went into the deeper water of the cove is another matter, and we would say so first.
I lost my ring at Stonesteps or Beacon's in Encinitas. Why does the tide matter so much?
Because those beaches can vanish. Stonesteps can disappear at high tide, and high tides can mostly wash over Beacon's (Leucadia State Beach). Both sit under bluffs, so stay well back from the base, photograph the stairs from where you were and message us. A search there is planned around the lower low tide.
Can a ring still be found at Carlsbad State Beach after the erosion?
Sometimes. Summer swells and high tides have stripped large sections of Carlsbad State Beach. Where the sand has gone, a ring can drop between cobbles, which is slow work but not hopeless. Where it has piled back up, the same ring is simply deeper. Tell us the date you lost it, because on this beach a few weeks changes the answer.
Should I try a metal detector rental in San Diego first?
You can, but mark the spot and take photos before you start. On a busy beach a borrowed machine mostly finds bottle caps, and repeated digging can push a ring deeper. Plastic sunglasses never show on a detector; those are found by eye or by a diver.
What if it cannot be found?
Some are not found. If the spot is vague, the loss was weeks ago, or a big swell has moved the sand since, we tell you before anyone travels. Costs are explained before any search is booked.

Leave a towel on the spot and send us a photo of it
Which beach, which tower or set of stairs, and what time it happened.
A marked patch of sand is worth more than any description, and on the bluff beaches the next high tide will take the whole beach anyway. Send the photo and the time on WhatsApp, and we will tell you what kind of search this is.
