Custom Jewelry Design


Whether you have a design in mind for any type of jewelry, or you’d like us to design something for you, we’ll turn your ideas and specifications into a finished piece. Bring a sketch, a photo, a stone you love or simply a description. Mark will help you choose the metal, the stones and the details, then make it by hand.

Jewelry Repair & Ring Sizing


From a ring that needs sizing to a broken chain or a worn setting, we repair fine jewelry with the same care we put into making it, including pieces you bought elsewhere. If another jeweler has told you something can’t be repaired, talk to Mark. The odds are he’ll tell you differently.

Stone Setting & Remounting


Have a diamond or gemstone that deserves a new home? We set loose stones securely and can remount a stone from an older piece into a new, handmade setting, giving a family heirloom a second life.

Creative Goldwork & Engraving


Hand engraving and fine goldwork have been part of Arendsen Jewelers since Norman Arendsen founded the business. Scrollwork, milgrain, textured finishes and sculpted details give each piece character that can’t be mass-produced.

Diamonds & Gemstones


The stone is the heart of every piece. Whether you have a classic diamond in mind or the rich color of a sapphire, ruby or emerald, we’ll help you find one with the cut, color and character you love, then set it by hand in a design made only for you.

The custom design process

How a custom piece comes to life

Every custom piece follows the same careful path, and you’re involved at every step.

  1. Consultation

    Tell us what you have in mind. Bring photos, sketches, a stone or an heirloom. We talk through style, budget and how you’ll wear it.

  2. Design

    Your idea becomes a design, with metal and stones chosen together so every detail is right.

  3. Approval

    We review the design with you and refine it until it’s exactly what you want.

  4. Handcrafting

    Mark makes your piece by hand, shaping the metal, setting the stones and finishing every surface.

  5. Final fitting

    We check the fit and finish with you, so your piece is ready to wear from the first day.

Kind words

Repairs our clients remember

“He ended up not only replacing the diamond, but redid all the prongs using much stronger material than it had originally. Price and service was amazing.”

Jesse E. · Google review

“I saw Mark at Arendsen and in less than 10 minutes he had the ring resized, polished, and looking better than it has in over 40 years. Best customer service ever.”
