Bring in your piece
A glimpse of what's in the case — engagement rings, everyday pieces, and statement diamonds.
For over 25 years, Jewelry by Allen Joseph has been a family-owned shop on Franklin Turnpike in Mahwah. For us, jewelry is personal — the engagement ring you'll wear for a lifetime, the heirloom you want restored, the gold you've decided to part with. Every customer is treated with the same honesty and care.
Whether you're designing something brand new, fixing something old, or simply curious what your gold is worth, we'd love to see you. Stop by — there's no pressure, just expert hands and a fair conversation.
"I totally trust this jeweler… they're trustworthy and tell you all the information about a piece you're going to purchase."
"THE BEST, HANDS DOWN!! Josie, Ferit and Allen are so wonderful to work with. Have been a customer for 20+ years. Ferit's custom design work is bar none — no other jeweler comes close! 10 million stars."
"Josie and family are always so helpful and informative… my engagement ring and wedding band are beyond stunning."
"Went there for the first time to get an anniversary gift for my wife. Josie was very helpful and patient in finding the right diamond necklace."
"The most honest jewelers I've worked with. I was robbed and some of my pieces were sold to them — I went in for a repair, saw them in the case, and they gave them right back to me."
"An amazing experience! I bought a gold chain, a cross pendant, and diamond stud earrings, and I couldn't be happier with the quality and craftsmanship."
Tell us what you’re after — a repair, a custom piece, a gold quote, or just a question — and we’ll get back to you, usually the same day.
