The ring she's never
seen because it
doesn't exist yet.
Custom engagement rings, heirloom remounts, and one-of-a-kind pieces — designed with you in our studio, rendered in 3D before anything is made, and handcrafted by our jewelers on-premises.
Before You Commit
Made In-House
to New York
Craftsmanship
Every piece begins
with a conversation.
Every ring, pendant, and custom piece you see was designed in our Newtown Square studio, rendered in 3D for your approval, and handcrafted by our own jewelers. No outsourcing. Ever.
Your vision,
realized.
Custom jewelry can feel overwhelming if you've never done it. Our process is designed to be the opposite — collaborative, transparent, and surprisingly enjoyable. You don't need to know exactly what you want. That's what we're here for.
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.
Design & Render
We design your piece in professional CAD software and produce a photorealistic rendering. You see exactly what you're getting before anything is made.
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.
Made Here
Cast and finished in our Newtown Square studio by our own jewelers. American craftsmanship, start to finish. Stamped ECJco inside every piece.
If you can imagine it,
we can build it.
From classic solitaires to sculptural statement pieces — our design capability has no limits. Every style, every metal, every stone. If it can be designed and cast, we can make it happen in our studio.
Engagement Rings
The most personal piece of jewelry you'll ever give. We design custom engagement rings from scratch — your stone, your style, your story. No two are alike.
Start the conversationHeirloom Remounts
Inherited a piece that doesn't fit your life? We redesign it into something you'll actually wear — honoring the stone and story while making it completely yours.
Bring it inCustom Pendants
One-of-a-kind pendants designed around your stone, your concept, or your vision. From delicate to dramatic — we've built them all.
Get startedWedding Bands
Custom bands designed to complement your engagement ring perfectly — or stand alone as a statement. Matching sets, stacking bands, engraved designs.
Design yoursAnniversary & Gift Pieces
Milestone gifts deserve something truly personal. A custom piece says what words can't — and lasts a lifetime.
Tell us your visionAnything You Can Imagine
Earrings, bracelets, brooches, cufflinks — if you can describe it, we can design it. Our studio has no limits on creativity or capability.
