Fine jewelry and custom design, jewelry repair, watch repair, and Briston watches. Everything is handled at the Bellevue Avenue studio. Repair estimates are free and given before anything is touched, and no appointment is needed to drop a piece off.
Monday to Saturday, 10:00am to 6:00pm.
250 Bellevue Ave, 2nd Floor, Upper Montclair. Walk in for a repair, or book ahead
for design and diamonds.
The studio is appointment driven, which means a booked visit is spent with the cases open and the stones out on the desk. Seven services sit under this heading, from a commission drawn from nothing to a stone sourced against a specification you arrive with.
A piece made from scratch, or an inherited one rebuilt into something you will actually wear. You sit down with the stones and the drawings before anything is committed.
Setting, metal and stone chosen together rather than picked off a tray. Natural or lab grown, with the price difference shown at matching specification.
Sourced to the cut, colour, clarity and carat you are actually after, with the certificate in front of you and the trade off between the four explained plainly.
The same chemistry and the same grading scale, at a different price. Shown next to a natural stone of matching specification so the comparison is yours to make.
Sapphire, emerald, ruby and the less obvious stones, hand selected per commission for colour and character rather than ordered from a catalogue.
The cases at Bellevue Avenue, chosen piece by piece. Rings, tennis bracelets, pendants and earrings, hung alongside work by the local artists the studio shows.
The studio is appointment driven, so a booked visit means the cases are open for you and nobody is waiting behind you. Monday to Saturday, 10:00am to 6:00pm.
Astra keeps natural and lab grown diamonds side by side and will set the two out at matching cut, colour, clarity and carat so the price gap is visible rather than described. Coloured stones are sourced per commission, which means sapphire, emerald, ruby and the less obvious ones are picked for the piece instead of pulled from stock.
Bring in something bought anywhere, in any condition. It is assessed with you, quoted free, and the work is coordinated through jewelers we trust. No appointment is needed to drop a piece off during opening hours.
Gold, platinum and silver sized up or down for a fit that stays put. The most requested job in the studio.
Snapped chains, broken links and worn clasps soldered and restored so the piece goes back into rotation.
Tightening, resetting or replacement, arranged before a stone that has started moving finds its way out of the setting.
Worn prongs are the single most common cause of a lost diamond. Rebuilding and retipping is coordinated to keep stones held.
Hinges, links, safety catches and stretched clasps repaired in matching metal rather than swapped for the nearest generic part.
Initials, dates and messages cut into rings, pendants and the inside of bands. Bring the exact wording and it is set out before cutting.
Scratched, dull and tarnished pieces polished and cleaned, heirloom and vintage included, with advice first where wear is part of the piece.
Older pieces brought back to wearable condition. What can be saved and what cannot is explained before you decide anything.
Most watch repair in New Jersey comes down to one of eight jobs. Each is listed with the turnaround actually quoted at intake, not an optimistic one. Movement work is coordinated through specialist watchmakers. Astra Jewelers is an independent jeweller, not an authorised service centre for any watch brand.
The correct cell fitted, the case gasket replaced and the caseback resealed, then pressure checked where the case allows.
Usually same visitSized on your wrist rather than estimated. Removed links are kept labelled with your name in case the watch or the wrist changes.
Usually same visitLeather, NATO, rubber or steel fitted with the right spring bars, so it does not part company with a cuff two weeks later.
Same visitScratched or cracked glass replaced in mineral or sapphire to suit the piece, with bezel and gasket refitted rather than forced back.
3 to 7 daysA crown that pulls out, spins without setting or will not wind. Usually a stem or tube problem, and usually fixable without opening the movement.
3 to 7 daysDeployant clasps springing open on their own are the most common cause of a dropped watch. Repaired or replaced in matching metal.
3 to 7 daysA full strip, clean, oil and regulate for a watch running fast, slow or stopping. Coordinated through specialist watchmakers.
Quoted at intakeBrushed and polished surfaces restored separately so the case keeps its original lines. Advised against where patina is part of the value.

Astra Jewelers is the only certified Briston dealer in New Jersey. The Clubmaster collections are stocked at Bellevue Avenue and fitted in person, which for a watch built around interchangeable straps and case colours is the difference between guessing and knowing.
Astra Jewelers in Upper Montclair, New Jersey covers four areas. Fine jewelry and design, which includes custom design, engagement rings, natural and lab grown diamonds, gemstone sourcing and curated pieces. Jewelry repair, including ring resizing, chain and clasp repair, stone setting, prong retipping, engraving and polishing. Watch repair, from battery replacement and link removal through to crystal, crown and full movement service. And Briston watch sales, where Astra is the only certified dealer in New Jersey. Estimates are free across all repair work and the studio is open Monday to Saturday, 10:00am to 6:00pm.
Repair drop offs need no appointment at all. Walk into 250 Bellevue Ave, 2nd Floor, Upper Montclair, NJ 07043 any time between 10:00am and 6:00pm, Monday to Saturday. Booking ahead is worth it for custom design, engagement rings and diamond viewing, because those visits are appointment driven so someone is free to sit down with you and pull stones rather than fitting you between drop offs.
Every repair is quoted per piece and the estimate is always free and given before any work starts. Astra Jewelers does not publish fixed prices because the cost of a resize depends on the metal and how many sizes it moves, and the cost of a watch service depends on what is found once the case is opened. Bring the piece in, or send a photo by WhatsApp for a first look, and you approve the price before anything is touched.
Watch battery replacement, link removal and strap fitting are usually done in the same visit. Crystal replacement, crown and stem work, clasp repair and polishing typically run three to seven days. Full watch movement service is quoted at intake because it is coordinated through specialist watchmakers. Jewelry repairs are given a realistic date when you drop the piece off, and Astra Jewelers calls you the moment it is ready.
Yes, both. Astra Jewelers in Upper Montclair stocks and sources natural diamonds and lab grown diamonds, and will show you the two side by side at the same specification so you can see the difference and the price gap for yourself rather than being steered. Gemstone sourcing for coloured stones is handled the same way, hand selected per commission.
