Our Work

Each piece begins
with a conversation.

Every ring, pendant, and custom piece you see was designed in our studio, rendered in 3D, approved by the client, and handcrafted by our jewelers in Newtown Square. This is what it looks like when nothing gets outsourced.

Our Story

Five decades.
One standard.

What began as Eastern Lapidary in 1975 has grown into East Coast Jewelry Co — still family-owned, still in Newtown Square, still holding ourselves to the same uncompromising standard we started with.

Today we design everything in-house using professional CAD software, 3D print every model before casting, and finish every piece in our studio. Laser welding, laser engraving, casting, stone setting, polishing — it all happens at 5048 West Chester Pike.

Most of our clients come through a referral. That says everything about how we work.

How It Works

Your vision,
realized.

Custom jewelry can feel overwhelming. Our process is the opposite — collaborative, transparent, and surprisingly enjoyable. You don't need to know exactly what you want. Nothing is cast until you love the design.

01

Consultation

Bring a photo, a sketch, a family heirloom, or just an idea. We'll shape it into something buildable — and beautiful. No obligation, no pressure.

02

Design & Render

We design your piece in 3D CAD and produce a photorealistic rendering so you see exactly what you're getting before anything is made. Revisions included.

03

Physical Model

We 3D print a wearable model of your design. Try it on. Hold it. Approve it in person. Nothing moves forward until you're certain.

04

Made Here

Cast and finished in our Newtown Square studio by our own jewelers. American craftsmanship, start to finish. Stamped ECJco inside every piece we make.

What We Do

Every service,
under one roof.

From a one-of-a-kind engagement ring to resetting a stone that's been in your family for generations — everything is designed and executed on-premises by the same team you'll speak with start to finish.

Custom Engagement Rings

Design the ring she's never seen because it doesn't exist yet. We work with you to create something entirely personal — your story, your style, your stone. Every step in our studio.

Start the conversation

Heirloom Remounting

Inherited a piece that doesn't fit your life? We redesign it into something you'll actually wear — honoring the stone and the story it carries while making it completely yours.

Bring it in

Custom Design

Pendants, earrings, bands, bracelets — if you can imagine it, we can build it. Every piece begins with a conversation and ends with something you won't find anywhere else.
