A borough named, as the story goes, for a miller who went west
Before it was Califon, the mill village on the South Branch was called California. Local history credits the name to miller Jacob Neighbor, who had gone west to the California goldfields in 1849. When the Central Railroad of New Jersey opened its High Bridge Branch through the valley, the station sign, so the telling goes, had no room for all ten letters, and the village became Califon. The borough itself was set off from Lebanon and Tewksbury townships in 1918.
In 1893 residents quarried fieldstone and hauled it to the rail line so the railroad would build them a stone station, the only one of its kind on the branch. That depot on Academy Street now holds the Califon Historical Society museum, and the rail bed beside it became the Columbia Trail after the line was abandoned. Follow the trail south toward High Bridge and it runs through the Ken Lockwood Gorge, where anglers stand in the river for trout.
What the karat on a Califon ring actually means
Most gold that comes from a small borough is worn gold: wedding bands, class rings, a charm bracelet, a chain with a broken clasp. Each carries a karat stamp, or used to before years of wear smoothed it away. 10K is 41.7 percent pure gold, 14K is 58.5 percent, 18K is 75 percent and 22K is 91.7 percent. European pieces often use the number instead, so 417, 585 and 750 mean the same three grades.
A stamp is a claim, not a proof. The XRF analyzer reads the metal itself in a few seconds, backed by an acid test, so a ring with a rubbed-off mark is judged on what it is, and a ring stamped 14K that reads lower is caught before anyone is paid on a guess. Pieces are grouped by the karat the machine reads, weighed on a certified scale, and priced at that day's live spot, one grade at a time.
Watching the karat read at the counter
“Walked into the Middlesex, NJ location to sell various gold & silver jewelry. Ed was very helpful and explained everything as he tested my jewelry to check if it was 10k or 14k or just costume jewelry. I felt very comfortable and was very pleased with the amount of cash I received. I plan on coming back with more jewelry.”

Old gold coins and silver halves from South Branch homes
A family that has lived along the river for generations often has a few coins put away: a gold piece given at a christening, silver half dollars, a Morgan dollar in a paper envelope. United States gold coins struck before 1934 are 90 percent gold, and silver dimes, quarters and halves dated 1964 or earlier are 90 percent silver. Both are worth at least their metal.
Some are worth more. Before any coin is valued as metal it is checked for date, mint mark and condition, because a scarce date or a well-kept coin can carry a collector premium well above melt. Leave coins uncleaned; polishing strips the surface a collector pays for. The coin buying page explains what lifts a coin above its metal.
Route 513 to I-78, then Route 28 into Middlesex
From the center of Califon, follow County Route 513 south through High Bridge to I-78 and head east. Take I-287 south, leave at the Route 28 exit for Bound Brook, and continue east on Route 28 into Middlesex, where the store sits at 748 Bound Brook Road. Allow about 34 minutes for the 27 miles.
Where in and around Califon do sellers come from?
The borough itself, from Main Street and Academy Street out to the river, plus the country roads that feed it: Route 513 north toward Long Valley and south toward High Bridge, the Columbia Trail corridor, and the farms of Lebanon and Tewksbury townships on either side.
What Califon sellers carry east
Mostly rings and chains, a few coins, sometimes a diamond. Open a category to see how it is judged.
How a Califon visit runs from start to finish
Hand over the pieces and your ID. Each ring is read by XRF and set with its karat group, coins go to one side to be checked for collector value, and any stone is looked at under magnification apart from its mounting. You see every reading and weight, and you hear one number per group at that day's live spot. Accept and you are paid in cash before you walk out; decline and every piece comes back to you as it arrived.

How far is the Middlesex store from Califon?
About 27 miles and 34 minutes: County Route 513 south through High Bridge to I-78 east, I-287 south, then Route 28 east into Middlesex to 748 Bound Brook Rd. Phone (732) 629-7600.
Can you tell the karat of a Califon ring whose stamp has worn away?
Yes. The XRF analyzer reads the metal directly, so a ring with no visible mark is graded on what it actually contains, with an acid test to confirm it in front of you.
What are 417, 585 and 750 stamps on jewelry?
They are karat grades written as parts per thousand. 417 is 10K, 585 is 14K and 750 is 18K, so a piece with one of those marks is priced exactly like its karat equivalent.
Are old gold coins from a Califon family collection worth more than melt?
Sometimes. Every coin is checked for date, mint mark and condition first. A scarce or well-kept coin can carry a collector premium; common worn coins are paid on their gold or silver content.
Do you buy from High Bridge, Long Valley and Lebanon Township as well as Califon?
Yes. Sellers along Route 513 in both directions, and from Lebanon and Tewksbury townships around the borough, all use the same route east to Middlesex.
When can Califon sellers come to the Middlesex store?
Monday through Friday from 10 to 6 and Saturday from 10 to 4; the store is closed Sunday. No appointment is needed, just a valid government photo ID.
