Made for you or found for you
The studio is appointment driven, which means a booked visit is spent with the cases open and the stones out on the desk. Engagement rings and custom design each have a page of their own, and the cards below link straight to them.
Custom Design
A piece made from scratch, or an inherited one rebuilt into something you will actually wear. The stone is chosen first, then you see a 3D rendering and wear a printed model before anything is cast.
Read the full pageEngagement Rings
Setting, metal and stone chosen together rather than picked off a tray. Natural or lab grown, with the price difference shown at matching specification.
Read the full pageWedding Bands
Matched to the engagement ring rather than picked separately, so the profile sits flush against it. Easier when both are designed together.
Read the full pageNatural Diamonds
Sourced to the cut, color, clarity and carat you are actually after, with the certificate in front of you and the trade off between the four explained plainly.
Lab Grown Diamonds
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.
Read the full pageHeirloom Resetting
An inherited stone out of its old setting and into something worn now. The stone is assessed with you first, because chips at the girdle hide under prongs for decades.
Read the full pageHeirloom Jewelry Redesign
Inherited pieces restored, reset or remade into something worn now. Where the metal is the memory, your own gold can go into the new piece.
Read the full pageSell Your Gold
Gold you no longer wear, weighed and tested in front of you on a certified scale and the number explained. Sell it, or have the same gold made into a new piece.
Read the full pageGemstone Sourcing
Sapphire, emerald, ruby and the less obvious stones, hand selected for each custom piece for color and character rather than ordered from a catalogue.
Read the full pageCurated Fine Jewelry
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.
Private Appointments
The studio is appointment driven, so a booked visit means the cases are open for you and nobody is waiting behind you. Monday to Friday, 10:00am to 6:00pm, Saturday until 5:00pm.
Natural, lab grown and colored
Astra keeps natural and lab grown diamonds side by side and will set the two out at matching cut, color, clarity and carat so the price gap is visible rather than described. Colored stones are sourced for each custom piece, which means sapphire, emerald, ruby and the less obvious ones are picked for the piece instead of pulled from stock.
Any piece from anywhere
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.
Ring Resizing
Gold, platinum and silver sized up or down for a fit that stays put. The most requested job in the studio.
Chain & Necklace Repair
Snapped chains, broken links and worn clasps soldered and restored so the piece goes back into rotation.
Loose & Missing Stones
Tightening, resetting or replacement, arranged before a stone that has started moving finds its way out of the setting.
Prong Repair & Retipping
Worn prongs are the single most common cause of a lost diamond. Rebuilding and retipping is coordinated to keep stones held.
Bracelet Repair
Hinges, links, safety catches and stretched clasps repaired in matching metal rather than swapped for the nearest generic part.
Engraving
Initials, dates and messages cut into rings, pendants and the inside of bands. Bring the exact wording and it is set out before cutting.
Polishing & Cleaning
Scratched, dull and tarnished pieces polished and cleaned, heirloom and vintage included, with advice first where wear is part of the piece.
Restoration
Older pieces brought back to wearable condition. What can be saved and what cannot is explained before you decide anything.
The eight most common jobs
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 jeweler, not an authorized service center for any watch brand.
Battery Replacement
The correct cell fitted, the case gasket replaced and the caseback resealed, then pressure checked where the case allows.
Quoted at intakeLink Removal & Resizing
Sized on your wrist rather than estimated. Removed links are kept labeled with your name in case the watch or the wrist changes.
Quoted at intakeStrap & Bracelet Fitting
Leather, NATO, rubber or steel fitted with the right spring bars, so it does not part company with a cuff two weeks later.
Quoted at intakeCrystal Replacement
Scratched or cracked glass replaced in mineral or sapphire to suit the piece, with bezel and gasket refitted rather than forced back.
3 to 7 daysCrown & Stem Repair
A 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 daysClasp & Buckle Repair
Deployant clasps springing open on their own are the most common cause of a dropped watch. Repaired or replaced in matching metal.
3 to 7 daysMovement Service
A full strip, clean, oil and regulate for a watch running fast, slow or stopping. Coordinated through specialist watchmakers.
Quoted at intakePolishing & Refinishing
Brushed and polished surfaces restored separately so the case keeps its original lines. Advised against where patina is part of the value.
3 to 7 days
The only certified Briston dealer in NJ
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 colors is the difference between guessing and knowing.
Common questions
What services does Astra Jewelers offer?
Astra Jewelers in Upper Montclair, New Jersey covers four areas. Fine jewelry and design, which includes custom design, engagement rings, wedding bands, natural and lab grown diamonds, heirloom resetting, 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 Friday, 10:00am to 6:00pm, Saturday until 5:00pm.
Do I need an appointment, or can I walk in?
Repair drop offs need no appointment at all. Walk into 250 Bellevue Ave, 2nd Floor, 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.
How much does jewelry or watch repair cost at Astra Jewelers?
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.
How long do repairs take?
It depends on the job. Watch battery replacement, link removal and strap fitting are the quickest work we do. 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. Every piece is given a realistic date when you drop it off, and Astra Jewelers calls you the moment it is ready.
Does Astra Jewelers sell both natural and lab grown diamonds?
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 colored stones is handled the same way, hand selected for each custom piece.
